About me
Hi, I'm Nitin — a senior full-stack engineer with 11+ years shipping commerce, FinTech, and agentic AI systems for global brands.
I've led delivery across headless commerce (commercetools, 10k+ SKUs), payments and underwriting (Plaid, Marqeta, Adyen/Stripe), OTT at Viu scale, and production AI agents (LangGraph, MCP).
I help students, freshers, and working engineers get hired and ship — resume positioning, career roadmaps, system-design mocks, and architecture unblocks. Not DSA tutoring.
On Topmate you will find:
• Instant digital guides from real production work
• Resume review (quick) and full ATS rewrite (done-for-you)
• Packages for interview switches and shipping + positioning
• Focused 1:1s when you need a human on the problem
Book what matches your stage. I'll meet you there.
