A bit about me
I'm a full-stack engineer with over five years of experience building secure, scalable products — mostly in FinTech and Healthcare. I've spent a good part of my career at Citibank, leading frontend modernization for systems used by millions, and more recently at a software craftsmanship consultancy building greenfield platforms from the ground up.
I care a lot about developer experience — the kind of tooling, testing practices, and architectural decisions that make teams ship faster without cutting corners. I'm an active member of the Software Craftspeople of India, and I believe clean code is a shared responsibility, not a nice-to-have.
Outside of work, I'm usually cooking something new, reading philosophy, or going down rabbit holes about system design. To be a pragmatic engineer is to stay curious about things beyond just code.

Where I've worked
Jan 2025 —
Senior Software Engineer
@ Incubyte Software CraftspersonBuilt a fault-tolerant full-stack SaaS platform for healthcare listings — NestJS, Angular 19, PostgreSQL on AWS. Introduced mutation testing in CI/CD pipelines, migrated cron-based systems to event-driven architecture with SQS and Lambda, and engineered agentic AI workflows that hit 100% adoption across two pods.
Aug 2020 — Nov 2024
Frontend Developer Lead
@ Citibank via Tata Consultancy ServicesLed the modernization of Citibank's authentication modules to a Next Generation Architecture in Angular 17 — strict ADA compliance, millions of daily users. Boosted sprint predictability by 75%, cut E2E build times in half with Module Federation, and saved $60K by building a local simulation environment for distributed mono-libraries.
