I have the basic framework of a Python-based web app up and running, but I need a seasoned developer to help me take it over the finish line. The app’s sole focus is data management, and I want it to excel at the three core functions I’ve already planned: Data storage, Data analysis, and Data visualization. Right now the project uses Python 3.11 with Flask, SQLAlchemy, and a PostgreSQL database. The back-end is roughly 70 % complete; models exist, routes are mapped, and authentication is in place. What’s missing are the polished features that turn this code into a product: optimizing queries, refining the analysis layer (Pandas, NumPy), and wiring up interactive charts (Plotly or ) so users can explore results in real time. A light React front end is already scaffolded...

I’m expanding a vetted network that places senior-level developers in long-term, high-paying roles with top-tier U.S. companies operating on CST, EST, and PST schedules. To join, you’ll need 4-6 years of solid professional experience building production systems in Java, C#, or Python, plus enough front-end know-how to collaborate comfortably with React, Angular, or Vue teams. Excellent spoken and written English (C1 or above) is essential because you’ll attend client-facing interviews and daily stand-ups. If you thrive in remote environments, can overlap at least four business hours with U.S. time zones, and enjoy tackling complex backend or full-stack challenges, let’s talk. What happens next once you apply: • A short screening call to confirm technical fi...

I run a production site on a Node.js + MongoDB stack and I’m looking to smooth out several pain-points in a single sprint. Performance is my top priority. The biggest bottleneck is database-side: query times keep climbing because of missing or poorly chosen indexes. I need someone who can audit the current collections, design the right compound indexes, and refactor slow aggregation pipelines. While you’re in there, I’d like basic search functionality so visitors can quickly surface records instead of scrolling through endless lists. Alongside the back-end tuning, there are a few infrastructure and UI tasks that will set the platform up for the next phase: • SSL certificate: generate or import the cert, configure it on the server, force HTTPS, and verify no mixed-...

I am assembling a new loan-processing platform and need a seasoned Node.js developer to stand up the entire backend. The core of the job is to architect and code secure user authentication and authorization, handle the full life-cycle of a loan application form, and build reliable payment processing with clear tracking of every transaction and status change. For data persistence I would like you to work with a SQL database—MySQL or PostgreSQL are both fine—so please structure your models and migrations accordingly. Beyond our own data store, the service must connect smoothly to several third-party providers: a credit-score API to pull applicant scores in real time, a payment gateway for disbursements and repayments, and notification services that let us push SMS and email upda...

Our shopping site is already up on a React-Node-MongoDB stack; now I need an experienced developer to take it over the finish line. Your main focus will be sharpening functionality, with special attention to robust search and filtering so customers can locate products quickly and intuitively. While you’re in the codebase, I also expect you to hunt down lingering bugs, tighten performance, and give the interface a final polish so it feels modern and consistent across devices. You will be working in a familiar environment—React (hooks, context or Redux), Express API, and MongoDB Atlas—so solid experience with that trio is essential. If you can blend in UI frameworks like Material-UI or Tailwind without bloating the bundle, even better. Key deliverables • Functional...

I’m expanding ReviewyAI from a promising prototype into a production-ready, autonomous code review engine. The immediate focus is twofold: first, integrating GPT-3 (with the option to swap in OpenAI or Anthropic APIs later) so the reviewer delivers highly accurate suggestions; second, re-architecting the backend so the system can serve a growing number of simultaneous users without losing speed or reliability. Here’s how I picture the collaboration working: • Frontend evolution – You’ll design and refine reusable components with Tailwind CSS, ensuring the interface feels fast and intuitive on any screen size. • AI-driven analysis – Wire GPT-3 into the Node/Express layer to inspect incoming code, score potential issues, and return actionable feed...

I’m building out a new React front-end and now need the server side to catch up. The priority is a robust Node.js backend that exposes well-structured RESTful endpoints returning clean, predictable JSON. The data layer will live in MySQL, so you’ll design the schema, set up migrations, and write queries or use an ORM—whichever keeps performance high and code readable. Although Laravel experience is welcome and I do plan to introduce a small GraphQL layer later, right now your main focus will be the REST API: authentication (token-based), role management, pagination, filtering, and solid error handling. Clear inline documentation and a concise README or Swagger / OpenAPI file should accompany each route so the React team can plug in immediately. I’m flexible on tim...

I already have a fully-built Node.js project (Apostrophe 3 CMS, v 4.8.0) zipped and ready to go. All I need is a smooth deployment to my Hostinger Business Node.js plan so the site becomes publicly accessible on my domain, no code changes, no feature tweaks. Key context • Node version on the server is 22. • Auto-deploy won’t work with ApostropheCMS, so it must be set up as a custom Node.js app. • I do not have SSH enabled on the account. Instead, I can upload through Hostinger’s File Manager and am looking for an alternative workflow that accomplishes the same npm install → npm run build → npm run prod sequence. The archive you’ll receive already contains , package files, all modules, views, public assets, scripts and ; node_modules is i...

I run a RO-based tech agency and I need a technical partner to take over running it. This post is specifically for technical freelancers and consultants who've already been running their own show — winning clients, scoping projects, managing delivery — and want to do it with an existing agency, team, and client base instead of building from zero. If you're a developer or architect who outgrew just writing code and started running your own consultancy, managing clients, and subcontracting to other devs — this is your role. This starts as a freelance engagement with a 2-week paid trial. If it works, this becomes full-time with a base salary + commission on new business. Partner-track, not employee-track. You get: an existing team of developers, active clients, and...

I need a part-time full-stack developer who is comfortable owning both the machine-learning pipeline and the web stack around it. The core assignment is to build and maintain a web application whose main feature is a ChatGPT-style chatbot, so practical experience creating, fine-tuning, and deploying conversational ML models is essential. You should be able to: • Design, train, and iterate on machine-learning models that power the chatbot, keeping latency low and responses relevant. • Wire those models into a modern web front-end and a secure, scalable back-end. Whether you reach for React, Vue, or another JS framework on the front and Flask, FastAPI, Node, or similar on the back is up to you—as long as you can justify the choice and move quickly. • Handle end-to...
