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...

We have an application based on Node JS . We need some work , intergration and ongoing work for it

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...

I’m ready to commission an end-to-end system that streamlines every core activity in my restaurant. The platform must let staff register customer orders effortlessly—whether those orders come from table service, the main cashier, or our Drive-Thru window—and route each ticket to the kitchen in real time. For payments, the system needs to accept cash, bank cards, and mobile wallets, closing each bill against the correct order source with minimal clicks. Clear audit logs are essential. On the staffing side, I want to create roles, assign granular permissions, and distribute daily tasks so each employee sees only what they need to see. Accurate, filterable financial reports are a must. At minimum I expect revenue, expense, and net-profit dashboards that can be exported to...

I have a fully-built dynamic website written in Node.js and I’m ready to take it live on AWS. The codebase is clean and sitting in a private Git repository; what I need now is an engineer who can handle the end-to-end deployment and leave me with a smooth, replicable workflow. Here’s the flow I’m imagining: spin up the right AWS services (EC2 or, if you think it’s smarter, Elastic Beanstalk or ECS), configure security groups, environment variables and SSL, hook the instance to our Git repo for zero-downtime updates, then connect the domain and verify that everything scales and logs correctly. If CloudFront or an RDS instance will help performance, let’s discuss—flexibility is fine as long as the final result is fast, secure and easy for me to maintain. ...

I need a Node JS service that pulls every piece of live information available on and its Android app (). The feed must refresh virtually every second, covering scores and statistics, detailed player profiles, and full match schedules. Your code should expose the data through robust JSON endpoints while respecting the target platform’s structure. Alongside the scraper, build a lightweight admin panel where I can: • Whitelist or block consuming domains / mobile apps in real time • View scrape and API-access logs at a glance • Add, edit or disable user accounts, assigning granular access rights Please design the solution so it can scale gracefully, use common Node JS tooling (TypeScript, Express, Puppeteer, Cheerio, or similar), and keep response latency low enoug...

I’m searching for someone who can comfortably switch between front-end and back-end work while also handling day-to-day bidding on freelance marketplaces for me. The development stack is flexible at this stage, so if you are equally happy working in React, Angular, Vue, Node.js, Django, Rails—or any comparable frameworks—feel free to bring your strengths to the table.

You will join our product team full-time to design, build, and maintain a real-time web application powered by Node.js and React. On the backend you’ll craft well-structured JavaScript services, optimise algorithms and data structures for speed, and handle event-driven flows with sockets, Redis, and WebRTC. On the frontend you’ll ship responsive React interfaces that consume those services smoothly. Our data layer runs on MongoDB, so you’ll model documents, tune queries, and manage indexing for performance and scale. Day to day you’ll touch every layer of the stack—from server-side architecture and deployment scripts to pixel-perfect components—so broad curiosity and independent problem-solving are essential. Core expectations • Deep JavaScript ...

My MongoDB Atlas cluster connects instantly through Compass, yet the same connection string refuses to cooperate inside my React project. The URI is tucked away in an environment variable, but at runtime I receive a generic “connection string” error and no data appears. I need someone to: • review how I’m importing the .env values and verify the string syntax • confirm the driver / library I’m using from the React side (or its Node-based API layer) is configured correctly for an Atlas URI • diagnose any authentication, whitelisting, or network nuances that Compass might mask • deliver a working example and a brief explanation so I can replicate the fix across environments Once the project builds and fetches data from Atlas without throwi...

I’m kicking off the creation of a brand-new web application and need a programmer who can guide the project from first commit to production release. You’ll take my concept and implement both the user-facing front end and the server-side back end, then deploy everything to a live environment. You are free to choose a modern tech stack—React, Vue, or plain JavaScript on the front end; Node.js, Django, or a comparable framework on the back end—so long as it results in clean, secure, well-documented code. Database design, API integrations, user authentication, and responsive UI are all part of the scope. I already have wireframes and a feature list ready to share once we start. Deliverables • Fully functional web application that matches the provided feature li...

I already have a production-ready library management platform running on a front end with a NestJS API, containerised with Docker and deployed on AWS (files are stored on S3). The missing piece is a compact student-tracking module that: • scans a student’s unique QR code on entry and exit • records the exact timestamps, the library section they visit, and calculates total duration of stay • appears seamlessly inside the current interface (no separate UI) The work involves adding the relevant pages/components in , extending the NestJS services and database schema, wiring in any AWS resources you need, and shipping the whole thing with full Jest unit/integration tests. Code quality must match the existing clean, typed, linted codebase; every new container or scr...

The codebase is a React front end that relies on Supabase for authentication, data storage, and real-time updates. A series of stubborn bugs have crept in—misfired auth callbacks, occasional data mismatches after writes, and visibly broken UI states when the websocket drops. Your first mission is to isolate and eliminate those issues so the app runs cleanly, with no console errors and all existing unit tests green. Once the core bugs are gone, I’d like a quick pass on the database schema (a couple of tables need index tweaks and a foreign-key adjustment) and help preparing a production deployment workflow. The stack is already wired to GitHub; I deploy to Vercel, but I’m open to your preferred routine as long as rollbacks are painless. Everything needs to be wrapped up ...

I am building a full-featured, PIPEDA/PHIPA-compliant telehealth platform focused on real-time patient consultations. The core functions are already mapped out: secure video calling, automated clinical-note summaries with audit trails, integrated e-prescribing, and role-based dashboards for patients, doctors, and admin/support staff. . Key tech I expect to see (or strong equivalents): React or Vue for the front end, Node.js or Django for the back end, WebRTC for calls, and a FHIR-compatible data layer. CI/CD is already configured in GitHub; you just hook your pipelines into it. On acceptance we will agree on milestone cuts covering: 1) role-based auth and encrypted storage, 2) video consult module, 3) e-script flow, 4) summary audit engine, 5) dashboards and final compliance review. Each...

I maintain several large, structured datasets spread across MySQL, PostgreSQL and SQL Server instances. Only portions of the existing schemas are documented, so the very first step will be to inspect each system, reverse-engineer any missing metadata and confirm table relationships. Once the landscape is clear I need all records extracted, cleaned, normalised and deduplicated, then merged into a single, well-organised MongoDB database. Your work should include a carefully planned document model that supports growth, fast look-ups and straightforward analytics. Proper indexing, sharding strategy (where appropriate) and query optimisation are critical because future workloads will be heavy and latency-sensitive. Please deliver: • An optimised MongoDB schema and architecture diag...
