I need a full-featured web application built from the ground up. The core idea and business logic are already defined; what I now require is the technical expertise to translate that concept into a secure, scalable, and user-friendly online product. Scope The job covers everything from setting up the project repository through to deployment on a live server.

Your scope calls for a structured full-stack build rather than a quick UI pass. I would confirm the primary user flows and data model first, then set up a clean repository with a responsive Angular/React interface, a versioned REST or GraphQL API, validation and security boundaries, and deployment configuration. I will deliver documented source, tests for critical flows, and a concise hand-off guide, with milestones for foundation, core workflows, and hardening. Please share the feature list, preferred backend/runtime, hosting, and any authentication or payment integrations so I can finalize the milestone plan.

A defined business logic with an open stack choice is the good kind of brief — it means the architecture gets picked for the problem, not forced to fit a preference. I'd lean React on the front end with Node or Django on the back, RESTful API, documented as I build rather than after, with tests and a one-click deploy script baked into the pipeline from day one, not bolted on before launch. Milestones I'd propose: architecture + core auth/data model first, then primary user flows, then polish + security audit + deployment — each with a working demo, not just a status update. After handover, 30 days of free support — any issue fixed as many times as needed. Feel free to check my profile for past work and reviews. What's the core product doing — that's what actually determines a realistic timeline and milestone plan.

Hi there, Fernando here from Mexico. I think you already have the business logic defined and need it turned into a maintainable application with the deployment and engineering standards handled properly. I’d use React for the frontend with a structured REST API backend, keeping the code modular, responsive and easy to extend. I’d build the primary user flows first, then add API documentation, unit/integration tests, deployment automation and a security review before release. I’ll also treat the under three second page load requirement as a development target rather than something checked only at the end, with performance measured during implementation. The first step would be establishing the repository structure, core application flow and API contract so the foundation can be reviewed early. Looking forward to work with you. Thanks Fernando

A REST list endpoint that returns every row inline works fine against a 50-row table in dev and stalls against a 5000-row table in production, which is why pagination, filtering and versioning belong in the API contract from the first route rather than bolted on once the frontend already expects a flat array. Since the feature list isn't locked yet, I'd rather build in a sequence you can verify at each step than commit to a full spec upfront. Repo and CI first, so the deploy script and environment config exist before there's anything to deploy against. Then the API layer, documented with OpenAPI or a GraphQL schema depending on what suits the data shape, with auth and the core data model matching the business logic you've already worked out. The frontend comes after, built in React or Vue against that same documented contract, so nothing gets wired against endpoints still moving. Tests land alongside the API and frontend, covering the core business rules first. Deployment closes it out, a one-click script plus a handoff guide covering environment variables, local setup, and how to extend it without me. M1: repo scaffold, CI, data model, deploy script skeleton, 42,500 INR, 4 days M2: API layer, auth, documented endpoints, 55,000 INR, 4 days M3: frontend build against the API contract, 55,000 INR, 4 days M4: test suite covering core business logic, 35,000 INR, 3 days M5: one-click deploy script, handoff guide, final wiring, 25,000 INR, 3 days

Your brief never says what the application does. Everything it lists - stack choice, Git repo, REST or GraphQL, tests, deploy script, hand-off guide - is scaffolding every web app needs. What actually determines cost is absent: what the product is, the user roles, the data model, external integrations, any compliance requirement. You say the core idea and business logic are defined. They are simply not in this post. So every fixed price on this page is a guess, mine included. What 150,000 buys instead: a paid discovery that turns your defined concept into a written scope and data model, then the first working slice - auth, roles and the primary user flow - deployed and in your repository. The remainder is fixed-priced against that document, so you compare a number to a scope rather than to a paragraph. Two acceptance criteria worth tightening before you award anyone: "No critical or high-severity vulnerabilities in final audit" - name the auditor or the tool. A third-party pentest is a real bar and I am happy to be held to it. An automated scanner mostly produces noise, and arguing over its output at sign-off helps neither of us. "Page-load under three seconds" - on which page, on what connection, measured how? LCP on a cold cache with production data is a different job from a warm dashboard load. Aakaash

The business logic is already defined, so the priority should be turning it into a clean product architecture rather than overcomplicating the technology stack. For this type of application, I’d recommend React for the frontend and a Node.js/Express REST API for the backend, with a relational database where the business data requires strong consistency. The exact stack can be adjusted after reviewing the requirements. My implementation would focus on: Responsive React UI across desktop, tablet and mobile Well-structured REST API with clear documentation Secure authentication, authorization and protected endpoints Proper database design and validation Clean separation between business logic, API and presentation layers Consistent error handling and logging Input validation and protection against common web vulnerabilities Unit and integration tests around critical business flows Performance optimization for the 3-second page-load target Environment-based configuration for development/staging/production Automated build and deployment process Git-based source control and clear documentation
