Jatin T.

I build and fix production web apps end to end: Laravel or Node.js on the backend, React or Next.js on the front, and AI features like LLM workflows, RAG and agents wired into real business logic. Top Rated Plus, 100% Job Success, 110+ contracts and 33,000+ hours.

Most of my work is one of three things:

• Full builds. SaaS platforms and business systems from data model to deployed UI, with one engineer owning the whole path: multi-tenant architecture, queues and background jobs, Stripe billing, PostgreSQL or MySQL data modelling.
• Taking over live codebases. Tracing someone else's business logic, fixing production issues under load, and shipping features without breaking what already works.
• APIs, integrations and AI. REST APIs, marketplace integrations (Amazon SP-API, Shopify), payment providers, and LLM features with Claude and OpenAI, including RAG, vector search and agent workflows, built with the retries, logging and guardrails that keep them reliable.

Backend: Laravel (including upgrades across major versions), PHP, Node.js, and Rust where performance matters.
Frontend: React, Next.js, Angular, Vue, Livewire, TypeScript.
Data and infrastructure: PostgreSQL, MySQL, Supabase, Redis, Docker, AWS, CI/CD.

I work in whatever your application already uses. I won't tell you to rewrite a working Angular admin panel in React because I prefer React.

Honest estimates, clear async communication, small reviewable changes, and I'll tell you when what you asked for isn't what you need.

If you have a web application that needs to get more reliable or do more, let's talk.
