Jitender JoshiFull-Stack Developer
Available for freelance work

I build things
that actually work.

Full-stack freelance development — from greenfield products to working inside your existing codebase. Whether you need a complete web app built from scratch, a new feature shipped fast, or a cloud infrastructure that scales — I cover the full stack end to end.

What I do

Services

Every engagement is scoped to what you actually need — not a fixed package with features you will never use.

Greenfield Web App

You have an idea, a problem to solve, or a product to launch. I take it from blank canvas to a production-ready web application — product thinking, architecture, design system, full-stack implementation, and deployment.

  • Requirements scoping and system architecture before a line is written
  • Frontend in Next.js or React with a polished, accessible UI
  • Backend API in Node.js, NestJS, or Next.js API routes
  • Database design — PostgreSQL, MongoDB, or Supabase
  • Auth, payments, file uploads, email — all the infrastructure pieces
  • Deployed to Vercel, AWS, or GCP with CI/CD pipeline

WORKFLOW // VERSION CONTROL & AGILE DELIVERY

How I run the build

Visibility is a deliverable too. Every project ships with structured version control, a hosted repo in your account, and short sprint cycles so you are never in the dark.

Version Control

Git — branch, commit, merge

Every project starts with a clean Git repo from commit one. Meaningful history, PR-based workflow, and automated checks so main never breaks.

  • Feature branch workflow
  • Conventional commits (feat / fix / chore)
  • Squash merges — clean main history
  • Semantic versioning & tagged releases
  • Pre-commit lint + type checks via Husky
Code Hosting

GitHub or Bitbucket — your call

The repo lives in your organisation from day one. You own the full commit history, the CI pipeline, and the deployment config — no handover needed.

  • Repo in your account or org from kickoff
  • PR reviews with inline comments
  • GitHub Actions / Bitbucket Pipelines CI
  • Branch protection rules on main
  • Full git history — yours permanently
Agile Delivery

1–2 week sprints, no surprises

Short delivery cycles keep scope tight and give you something testable every sprint. You always know what is in progress, what is next, and what changed.

  • 1–2 week sprint cycles
  • Async written standup updates
  • Live demo at the end of each sprint
  • Backlog you can read and comment on
  • Scope changes handled as new tickets

How we work together

Engagement types

Pick the structure that fits your situation. Most clients start with a sprint or dedicated build, then move to a retainer once the product is live.

Sprint Engagement

1–4 weeks

A focused, time-boxed sprint on a specific feature, integration, or deliverable. You know what needs to be built — I come in, build it cleanly, and hand it over with documentation.

Good fit for

  • New feature on an existing product
  • Third-party integration
  • Performance fix or refactor
  • Proof of concept or MVP slice

Dedicated Build

1–6 months

Full-time dedicated work on building a product from scratch or a major new module. You get my full attention — daily updates, weekly reviews, and a clear milestone structure.

Good fit for

  • Greenfield web application
  • Platform rebuild or migration
  • New product line or vertical
  • Complete feature area from design to deployment

Team Extension

Ongoing

I embed in your team as a senior full-stack engineer — attending standups, reviewing PRs, contributing across the stack. Works well for teams that need bandwidth without a full-time hire.

Good fit for

  • Startup scaling their engineering team
  • Agency needing extra capacity on a client project
  • Product team shipping a large feature set
  • Technical co-founder support

Retainer

Monthly

A reserved block of hours each month for ongoing work — bugs, small features, infra updates, and technical advice. You get priority access and consistent context without hiring full-time.

Good fit for

  • Post-launch maintenance and iteration
  • Regular feature additions at a sustainable pace
  • Technical advisory alongside your in-house team
  • AMC-style support for an existing custom system
