Ankit Kumar Mishra

Engineering Lead | Full-Stack Engineer

Most recently Staff Software Engineer at TechPassport, London, UK

Summary

I'm a Full-Stack Engineer and Engineering Lead with 6+ years building systems that move money and verify people: payments, billing, KYC and compliance, and the infrastructure underneath them.

Most recently I was a Staff Software Engineer at TechPassport, a London RegTech platform, where I owned the monetization stack end to end. I built it from scratch: Stripe integration, subscription management, and the full billing schema. I also cut API response times by 75 to 80% across the platform's critical endpoints, and I ran the design-to-engineering pipeline in Figma, shipping features from concept to production.

Before that I spent two years at Vested Finance, an investment platform handling live investor funds. I joined as a Software Engineer and was promoted twice in 12 months to Engineering Lead, running the KYC/Compliance and Premium Management squads as de facto product owner. We took onboarding from a single market to global users and unified subscription billing across Stripe, Razorpay, Google Play, and Apple in-app purchases.

Outside work I build with LLMs (tool calling, RAG, agents, MCP) and have mentored 1,000+ developers as a Subject Matter Expert.

Teaching

Subject Matter Expert and lead instructor across several engineering schools. I'm an engineer first. Running 50+ live batches and 1:1 coaching sessions is why I can take someone from stuck to shipping, write a review that teaches rather than blocks, and set technical direction a squad will actually follow. Scale: 50+ live batches taught, 50-100 engineers per batch, 1,000+ developers mentored. Platforms: Codecademy, Coding Ninjas, Masai School, Cuvette, AccioJob.
