Our SaaS platform is already live, but I want a seasoned React / and Node.js developer to give it a rigorous technical once-over so we can scale with confidence. The immediate focus is a full codebase and architectural review, making sure every module is clean, maintainable, and truly production-ready. Performance is the headline goal. Please profile and tune the areas that matter most to us: dashboard load time, API response time, and the heavier database queries that power our charts. I expect concrete, measurable gains—think quicker Time to First Byte, lower p95 latencies, and smoother UI interactions—without sacrificing code clarity. While you are in the weeds, scrutinise the onboarding flow that starts with a user’s API token and ends with an activated account. An...

My in-house software engineer has brought our short-video social app to a functional beta, but we still need polish and rock-solid stability before launch. I’m looking for a collaborator who can jump in quickly and help us close the remaining gaps in two areas: 1. User Interface • Refine design elements so every screen feels consistent, modern and on brand • Tighten the navigation flow from feed to profile, camera, and discovery to keep interactions friction-free • Implement responsive user-feedback mechanisms (loading states, haptics, subtle animations) that make the experience feel as snappy as TikTok 2. Backend Integration • Harden database connections and optimise queries for real-time feed loading • Clean up API handling, ensurin...

The core of my learning platform is already live: a React front end talking to a Node-Express API with PostgreSQL, secured by JWT, and enriched with a custom Rich-Text Editor, ECharts dashboards, and IndexedDB offline mode. Where I now need your help is the AI layer that creates quizzes and content summaries through Groq and Google GenAI. I want to push this module further in three directions at once—accuracy, new feature depth, and raw performance—without disrupting the existing users. Scope of work • Audit the current prompt engineering, model selection, and caching strategy, then tighten it so the generated questions better match source material and difficulty settings. • Extend functionality: additional question types (e.g., drag-and-drop, image-based), adjust...

We are looking for a MERN specialist who can take full ownership of a production-grade web application. The immediate focus is on modelling a complex data structure: expect dense many-to-many relationships that demand rock-solid data integrity and expressive, lightning-fast queries in MongoDB. Beyond the database layer, you’ll be building and hardening REST endpoints in Express/Node, wiring in third-party services, and tying everything together with a clean React front-end. Firebase will handle authentication, real-time messaging, and push notifications, so any prior experience there is a plus. On the infrastructure side, you’ll manage Docker-based deployments to AWS or DigitalOcean, keep CI/CD pipelines humming, configure domains and SSL, and watch logs and uptime dashboa...

Dear [Agency Name / Team], I hope you are doing well. I am currently developing an e-commerce mobile application and website, which is already in an advanced stage of development. The core architecture and major feature sets have largely been completed by my existing full-time team. As the project transitions from heavy development into refinement, optimization, feature enhancement, and maintenance, I am looking to migrate to a lean, part-time engagement model to ensure cost efficiency while maintaining technical stability and scalability. Project Overview Project Type: E-Commerce Mobile App & Website Current Stage: Advanced Development / Pre-Launch Optimization Engagement Model Required: Part-Time / Dedicated Support Existing Technology Stack Our platform is built using: Backend: Node...

The project covers two linked assets—a marketing website and an interactive web application—built as a single, cohesive code-base. Everything must be modern, fully responsive, and branded with a clean, intuitive UI/UX. Tech stack is already set: Angular on the frontend and a Node.js (Express) backend. Expect secure, stateless authentication (JWT or OAuth, whichever you judge best), role-based access, and a well-structured REST API that can later expand to GraphQL if needed. Data will live in either MySQL, PostgreSQL, or MongoDB; I’m open to whichever you recommend once requirements are refined. Core functionality • Public-facing pages for visitors • A logged-in web app with real-time notifications • Separate admin dashboard for user, content, and sett...

I’m preparing to launch a new initiative called “150.000koin” and need an experienced developer to help shape the technical side of the project from the ground up. Because the concept is still being finalized, I’m looking for guidance on which platform—web, mobile, or desktop—will best fit our eventual goals, as well as practical recommendations on architecture, security, and scalability. Key objectives: • Clarify and document the core functionality that will power 150.000koin. • Propose a technology stack that balances performance, cost, and ease of maintenance. • Deliver an initial, working prototype (basic interface plus back-end logic) that demonstrates main workflows such as user registration, asset tracking, and secure transact...

The goal is to design a future-proof relational backbone for a multi-channel retail platform, built natively on PostgreSQL. I already run an operational system, and its live transactional records will have to be migrated into the new structure without downtime. Everything else—users, inventory, orders—will start fresh. Core design expectations The operational schema should be fully normalised to 3NF and optimised from day one for high concurrency. Think table partitioning (range and list), well-chosen GIN and B-Tree indexes, plus JSONB columns where semi-structured flexibility makes sense. Triggers, constraints and stored procedures must enforce business logic consistently, so the application tier can stay lightweight. Analytics layer Alongside the OLTP schema I need a se...

What this project does: • Centralizes employee records and profiles • Simplifies attendance tracking and time management • Enables streamlined HR workflows • Helps improve productivity and reduces manual processes This solution brings several key benefits that modern HR systems aim for: improved operational efficiency, better...

I need a full-stack website that lets visitors request our “Cloud” home service and gives me a robust admin panel to run everything behind the scenes. The site has to be deployed on Microsoft Azure, so please structure the code and infrastructure (App Service, SQL/NoSQL, storage, CI/CD if you prefer) accordingly. Front-end • Modern, responsive landing page that explains the service and captures leads or direct bookings. • Clean contact/booking form with validation and confirmation emails. Admin panel requirements • User management (create, edit, suspend customers and staff). • Service booking management with status updates, filters, and search. • Analytics & reporting—at minimum daily/weekly booking counts and user stats, shown i...

I’ve put together the entire front-end of my React Native app and now I’m ready to connect it to a real backend. During a live Zoom or Microsoft Teams session I want to screen-share and work side-by-side while you guide me through each step. Supabase is the database service I’d like to use (or firebase), though I’m open to brief comparisons with Firebase if a decision point comes up. I have no prior backend experience, so you’ll need to walk me through project structure, environment variables, and deployment best practices. Whether the supporting server logic ends up in Node.js or another lightweight option, keep everything clear and beginner-friendly so I can maintain it afterward. We must cover: • Authentication setup – phone OTP authentication....

I’m building Curacare, a full-stack web app that lets people handle medical emergencies without scrambling for information. The heart of the platform is a seamless doctor-consultation flow, so the appointment-scheduling module has to feel effortless on both mobile and desktop. Alongside that core feature, users must be able to reach hospitals instantly through a dedicated “Contact Hospital” pathway—click-to-call, email, or any direct channel you suggest—surfaced within one tap from the dashboard. Speed and reliability matter more than bells and whistles: every interaction should load in under a second, and every piece of patient data must be encrypted at rest and in transit. Tech-stack choices are open, though I’m leaning toward a React front-end, ...

I want to turn my “my tool sharing” idea into a live web platform, handling everything from the first pixel of the interface to the last line of server code. At its heart the site needs one thing done perfectly: users must be able to list their tools and let others search for them quickly and intuitively. This first phase focuses only on that listing-and-search workflow. Reviews, ratings, booking calendars, and other extras can wait, so please build the architecture with clean separation of concerns to make those future add-ons painless. You are free to choose a modern stack—React, Vue, or vanilla JS for the front; Node, Django, Laravel, or a similar framework for the back—so long as the code is well-documented, componentised, and backed by a reliable database su...

My team needs a seasoned full-stack developer to step in as a consultant who can transfer knowledge rather than write code. I’m specifically looking for someone confident across frontend, backend, and database layers who can translate that depth into clear, structured technical training sessions. Your core mission is to design and deliver training that sharpens our developers’ practical skills. Expect to break down real project scenarios, walk through architectural decisions, explain code quality best practices, and answer ad-hoc questions as they come up. We work mostly with JavaScript/TypeScript, React, Node.js, and PostgreSQL, so fluency in these (or closely related stacks) will help you connect quickly with the team. Deliverables • A short training plan outlining top...

I’m searching for production-ready AI agents I can roll out across several verticals—specifically Healthcare, Real Estate, E-commerce, Blockchain, Crypto, and Social Media. Each solution must already be live somewhere so I can see it operating in real time before we move forward. The core requirements are straightforward: the agent needs to run in a browser, accept its own knowledge base or document set for context, and ship with source code plus clear documentation. I’m also expecting help getting the code stood up in a SaaS or on-prem environment. I’m flexible on architecture; whether you built it around OpenAI, Claude, Llama, FastAPI, Node.js, Pinecone, FAISS, or Weaviate doesn’t matter as long as it performs reliably at scale. To keep things simple, here...

I’m building a mobile-only app that needs a real-time text chat backend dedicated to one-on-one conversations. The goal is a lightweight, low-latency server that can authenticate users, deliver messages instantly, store chat history, and scale as the user base grows—all without the overhead of group or public room logic. I’m open to proven stacks such as Node.js with WebSocket/, Go with gRPC, or an equivalent solution that plays nicely with iOS and Android clients. End-to-end encryption, push-notification hooks (FCM / APNs), and a RESTful or GraphQL API for ancillary data are highly desirable. Deliverables • Production-ready server code with clear setup instructions • Secure user authentication and encrypted message transport • Message persistence (Mo...

I’m building a high-end real-estate lead engine that can capture, qualify, and route 150–200 fresh inquiries every week with a hard 99.5 % uptime target. Instead of a generic chatbot, the core of this MVP is a lightning-fast Custom Qualification UI written in React, backed by a Node.js API and a PostgreSQL (or comparable SQL) data store. What I need from you is end-to-end ownership of the stack: solution architecture, clean code, robust testing, and cloud deployment. The product must open the door for future add-ons such as a real-time analytics dashboard, but for this first milestone the focus is on: • Lead scoring system that assigns quality grades the moment data arrives • Automated lead routing that pushes hot prospects to the correct broker or CRM queue wit...
