How I Work

My Process

01
Discovery Call
We talk through your requirements, timeline, and tech constraints. I ask the hard questions upfront so there are no surprises later.
02
Scoping & Proposal
I break down the work into milestones with clear deliverables, timelines, and a fixed quote. No vague estimates.
03
Build & Ship
Weekly check-ins, async updates, and a staging URL so you see progress in real time. Code is clean, typed, and documented.
04
Handoff & Support
Full deployment, documentation, and a 2-week support window post-launch. You own everything — code, infra, and all credentials.

What People Say

Tanujeet delivered a backend API that handled our peak load of 400+ concurrent users without breaking a sweat. Knew exactly what to build and shipped it clean.

The distributed job scheduler he built replaced a fragile cron setup we'd been fighting for months. Reliable, well-documented, and deployed in under a week.

CTO, B2B SaaS

Integrated GPT-4 into our existing Next.js app with auth and rate limiting in one sprint. Communication was clear and code quality was exactly what we needed.
