About
Who is Saiful Khan?
Full stack developer — frontend, backend, database and deployment, owned end to end.
Saiful Khan is a full stack developer with eight years of experience building production web applications end to end. He takes a product from an empty repository to a live, monitored system: interface, API layer, database schema, authentication, payments, deployment pipeline and handover documentation.
His day-to-day stack is TypeScript across the whole system — React 19 and Next.js on the client, Node.js and typed APIs on the server, PostgreSQL and Supabase for data, Redis for caching, Docker and CI/CD for delivery, deployed to Cloudflare, Vercel or AWS. One language, one type contract, from the form field to the database column.
He works the same way on every project: understand the business constraint first, design the data model and the API before any screen, then build the interface against real data. Performance budgets and error budgets are set at the start and enforced in CI, so releases stay boring and predictable. Recent builds include a commerce platform that lifted revenue 31%, an operations system that removed 1,900 manual hours a month, and a content platform serving 200k pages at sub-second response times.
Saiful works remotely with founders and product teams worldwide, either as the sole developer on a new build or embedded with an existing engineering team. Every engagement ends with a documented system your team owns and can operate without him. Available for new full stack projects — email hello@saifulkhan.com.

Data model before screens
Saiful Khan designs the schema and API contract first, so the interface is built against real data instead of guesses.
Performance is a feature
Sub-second interaction budgets, enforced in CI and measured on real devices, on every single release.
You own the codebase
Typed, tested and documented. Every build is handed over so your team can extend it without the original developer.
