My Verifone VX520 is already working fine online, but I still have to keep business running when the network goes down. I need the terminal to keep a complete, reliable record of every purchase while it is offline, then upload the data once connectivity returns. In short, I want transaction logging fully activated and tested in offline mode. If you have hands-on experience with VX520 parameter setup, EMV kernel options and the usual Verifone configuration tools (VX Manager, PC Load, or comparable utilities), you will feel right at home here. I can provide remote access to the terminal or share current parameter dumps—whatever you need to move quickly. Acceptance criteria • VX520 successfully stores each sale locally with all mandatory fields (amount, PAN mask, date/time, aut...

I’m building an intraday futures setup on NinjaTrader 8 and need the entire workflow coded and tested within the next month. The core logic is a trend-following strategy written in C# / NinjaScript, but key calculations and data handling will sit in a companion Python module, so smooth, low-latency communication between the two languages is essential. Here’s what the job entails: • NinjaScript side: create a clean, well-commented NT8 strategy that reads signals, submits/updates orders, manages stops & targets, and records trade metrics for later review. • Python side: expose functions that generate my trend-following entries, manage position sizing, and push any analytics back to the NinjaScript layer. • Integration: set up whichever bridge you prefer&m...

A Windows-based trading bot has to sit between a Telegram signal channel and my Bybit account, duplicating every position with absolute accuracy. Two limit orders per direction, hedge mode, dynamic leverage, automatic re-entry, and a five-step pyramid that increases both margin and leverage are mandatory. Once price reaches my defined level, the position must move to break-even and follow a trailing (talking) stop; old trades should be closed and cleared from the log after a user-set number of hours. The bot must stay online 24/7, recover gracefully after a restart, and send every fill, modification, and error message back to me via Telegram. Stability and robustness are non-negotiable, but the most critical acceptance tests are: • Pyramid logic executes each of the five layers wi...

PROJECT SUMMARY: I need an experienced RF/NFC hardware engineer to design a compact, modular 4×4 NFC sensor array board. The board will be used to detect and identify NFC-tagged objects placed on a flat surface (e.g., industrial tray, logistics sorting grid, or interactive tabletop application). Multiple boards (up to 6) will be tiled together to cover larger surfaces. Each board must detect and report the UID of ISO 14443 and ISO 15693 NFC tags placed on any of its 16 positions, within 500ms scan time for the full array. This is not a greenfield project. I have an existing but non-functional 6-layer PCB design (EasyEDA source files available) that attempted this with an ST25R3916B, STM32L476, analog multiplexers, P-MOSFETs, and PIN diodes simultaneously. The design is overenginee...

I have a C# application that is now locked behind WinLicense + Themida 3.x. My only goal is to regain access to the project so I can open it in Visual Studio and continue working on it. I do not need a ready-to-run executable; what I’m after is clean, compilable source code. Once unpacked, I want to see: • the full user-interface layout and resources, • the core functionality and algorithms, and • all data-processing and storage routines. A straightforward Visual Studio solution (.sln, .csproj, assets, references) with clear build instructions will be considered a complete delivery. If any sections remain obfuscated, please document the reasons and suggest next steps.

I have already drafted a full specification for a simplified television remote control aimed at older users, complete with ergonomics, button layout, and overall product vision. While I finish the patent application, I now need a skilled partner to bring the electronics and software to life. On the hardware side, the priority is circuit design. I will share detailed functional blocks, power-budget targets, and regulatory constraints; you would translate these into a clean schematic that is ready for board layout (I will also welcome help on the actual PCB routing once the schematic is locked). For software, I need both the embedded code that will run on the microcontroller and the on-screen user interface logic that appears on the TV. Simplicity and reliability for elderly users are the ...

I’m building a ROS 2 pipeline that must reliably spot nuts and bolts in a live camera feed and publish their positions to the rest of my stack in real time. Your job is to create the complete vision-detection module—from model training or fine-tuning through to a clean ROS 2 node that subscribes to an image topic and spits out the detected objects with bounding boxes (or masks) and a confidence score. OpenCV, TensorFlow/PyTorch and any of the common ROS 2 image-transport plugins are all fine as long as the final node runs on Humble and stays GPU-agnostic (CUDA acceleration is a bonus, not a requirement). I already have a test rig with a standard USB camera; if you need specific calibration images I can capture them for you. Please deliver: • Source code for the detection...

I’m looking to license or purchase a complete, already-finished Triple Chance slot game that runs smoothly on Windows desktop PCs. The build should be plug-and-play for me: install, launch, and the reels spin exactly like the classic Triple Chance experience. A key requirement is a built-in print function so the game can immediately send ticket or voucher information—winnings, session data, or simple receipts—to any standard Windows printer without extra configuration. The printer call must fire automatically after each game session or via a clear “Print” button inside the UI. I’m flexible on the underlying technology; Unity, C++, C#, or any stable framework is acceptable as long as it installs cleanly on current Windows versions and does not depen...

My current Python script runs without throwing syntax or runtime exceptions, yet the results it produces are clearly off. I need a fresh set of expert eyes to trace the logic, pinpoint why the calculations deviate from what I expect, and then adjust the code so it returns accurate outputs every time. You will get the full source file and a quick note on what the correct outcome should look like. From there, I’m counting on you to: • Identify the specific logical missteps in the flow or calculations • Correct them cleanly, keeping the code readable and well-commented • Hand back a working version along with a brief explanation of the fix, so I understand what went wrong and how you resolved it The task should be straightforward for someone comfortable with Python...

I want a clean, well-documented Python application that plugs into the Fyers REST API and runs a fully automated intraday strategy. The logic is straightforward: a Moving Averages crossover confirmed by a Relative Strength Index (RSI) filter triggers entries, then the system exits when the opposite MA crossover appears or a user-defined RSI level is hit. Time-frames (1-min, 5-min, etc.) and all indicator parameters should be editable from a single config file so I can tweak the behaviour without touching the code. The program must: • Authenticate to Fyers using my API keys, refresh tokens automatically, and reconnect on dropouts. • Stream live market data, compute the MAs and RSI in real time (pandas_ta or TA-Lib are fine), and generate long/short orders the instant conditions...

I am ready to acquire a fully-packaged trading solution that has already been stress-tested in live conditions and is verifiably profitable—minimum 60 % return over a meaningful sample of trades. The system must trade across Forex, Crypto, and CFD markets, and it has to be plugged into an automation layer (bot or API integration) so I can deploy it immediately. Risk management is my top priority. Your method should demonstrate clearly defined position sizing, draw-down limits, and safety nets that have held up in both back-tests and live accounts. Without robust controls, the proposal will not be considered. To streamline selection, send a detailed project proposal that includes: • Strategy documentation explaining the logic, indicators, and time-frames • Proof of perf...

Don't forget to write your Github or Gitlab profile on the top of bid. If not, will ignore it. I’m building a full-featured desktop application and need an experienced Qt developer who is completely comfortable working in modern C++. The core of the job is to take my functional requirements, translate them into a clean Qt-based architecture, and deliver a polished, installable application that runs smoothly on Windows (and ideally macOS/Linux if you can accommodate cross-platform targets). You’ll be responsible for designing and wiring up the entire UI with Qt Widgets or Qt Quick—whichever best suits the final UX—while also implementing the underlying logic in efficient, well-documented C++. Robust error handling, responsive layout behaviour, and adherence to ...

I need help steering an LLM through a realistic engineering workflow on an open-source Python library. Your first step will be to choose a mature, well-documented GitHub repo that ships as a library or package and can be cloned and built with nothing more exotic than standard pip dependencies. Once the repo is agreed upon, you will frame a single, well-bounded engineering assignment for the model—perhaps a small feature, a non-trivial refactor, or a robust test suite—something neither superficial nor sprawling. From there you will run an iterative review loop: prompt the model, inspect its MR, request changes, and continue until the contribution is truly production-ready. That means the patch must follow project style, cover edge cases, include unit/functional tests, update do...

I have a 32-bit native Windows program that is still wrapped with Enigma Protector 4.x. I need the protection completely removed so I can freely modify and rebuild the binary. My own disassembly workflow is done in IDA Pro, so the final file must load cleanly there without any of Enigma’s obfuscation layers, virtual machines or anti-debug tricks. What I expect from you: • A fully unpacked, runnable executable whose behaviour matches the original one‐to‐one. • All sections properly restored, with imports, relocations and resources intact. • No remaining Enigma stubs; the file should be traceable and patchable in a standard debugger. Fast turnaround is important—I’m ready to test your output as soon as it is delivered and approve payment immediately...

I need a small utility that hooks into a PC game built on a custom engine and, at run-time, captures three things per frame: • the full 4×4 view-projection camera matrix • the depth buffer in linear space • the raw, uncompressed RGB back-buffer All data should be written straight to disk in a clean, well-documented CSV schema so I can feed it directly to my AI training pipeline later. Resolution, frame interval and output folder must be user-configurable through simple flags or an .ini file. I am comfortable providing you with a private build of the game plus symbols; the rest of the reverse-engineering or graphics API interception logic is yours to implement. Feel free to rely on tools such as RenderDoc, NVIDIA Nsight, Detours, or your own DLL injection met...

I need a Windows-based desktop application that turns a single still image into an AI-generated video, entirely offline. The workflow should rely on a local Stable Diffusion installation and incorporate the WAN2.6 model to drive the final animation—no external API calls, cloud processing, or telemetry of any kind. Core requirements • Runs natively on Windows 10/11 and installs with minimal user setup. • Accepts at least JPEG files for input; adding PNG or BMP later should remain possible. • Generates a short video (MP4 preferred) by feeding the image through Stable Diffusion and WAN2.6. • Interface must feel intuitive for non-technical users while exposing advanced settings in an “expert” panel. • Conversion speed is critical; please op...

Generic diagrams, flowcharts, AI-generated explanations or conceptual images will NOT be considered valid submissions. Technical Objective Device: Pixel 8a (akita) ROM: EvolutionX 15 (Android 15) Root: Magisk + Zygisk + LSPosed Goal: Force a USB UVC external camera to behave as the ONLY usable system camera. Requirements: Any app requesting a camera must open ONLY the external USB UVC camera. Internal physical cameras must be unusable or invisible. No ROM building. No vendor mod...

I’m building an Android-based equalizer app whose very first mission is solid, low-level I2C communication. The app must be able to discover and talk to an external audio-amplifier chip on the bus, read and write its registers in real time, and let a physical remote-control key trigger those same EQ changes inside the UI. I2S handling can follow later, but rock-steady I2C comes first. You may choose any practical route—GPIO lines available on an Android SBC, a USB-to-I2C bridge, or another proven method—so long as it runs on a stock Android build. I can supply the amplifier’s data-sheet and register map as soon as the project starts. Deliverables • Full Android Studio project (Kotlin or Java) with clean, well-commented source • Working APK that finds...

I have a small STM32-based prototype that needs a tidy firmware layer to read a digital sensor running off the 3.3 V rail and perform on-board data processing. The task is focused purely on sensor data acquisition and manipulation—no motor control or external comms stacks are required beyond whatever interface the sensor ultimately uses. Scope • Bring-up of the chosen digital interface (we will settle on the exact line once we start). • Continuous sampling with lightweight processing: basic filtering/averaging and a simple validity check. • A clean API or callback so the main application can fetch the processed values. • Well-commented C code in a CubeIDE or bare-Makefile project plus a short README explaining pin assignments, clock config, and how to rep...

I would like a clean, external-only cheat for Rainbow Six Siege with ESP as the headline feature. My absolute priority is seeing opponents and their gadgets through walls and floors in real time, so rock-solid Player ESP and Gadget ESP come first. A toggle-able in-game menu is a must so I can quickly enable or disable each overlay. Secondary niceties such as a basic aimbot and a recoil controller are welcome, but they should never compromise the stability or stealth of the ESP layer. I expect the build to stay out of the game’s memory space, communicate with the game via external reads/writes, and remain undetected by the current BattleEye release. Deliverables • Compiled external cheat (.exe or similar) with Player ESP and Gadget ESP working on the latest R6 patch &bull...

I need a seasoned embedded-systems engineer to help me complete and refine firmware for an industrial solar tracking pilot we are about to install in the field. The hardware platform is an STM32-based control board that already handles basic I/O; what I need next is rock-solid actuator control logic and tight integration with the rest of the system. Key priorities • Linear-actuator position control is the single most critical feature. Accurate sun-tracking algorithms must translate to smooth, repeatable movement, end-stop detection, stall handling, and safety interlocks. • The board talks over a CAN bus to a Linux-based gateway. Your code should package position reports, health data, and fault codes into our existing CAN message set and respond to incoming commands in real t...
