Senior Software Engineer
Backend · Platform

I build the backend platforms other teams build on — payments, workflow orchestration, partner onboarding, and the event-driven plumbing that keeps thousands of insurance transactions moving every month.

Profile

I'm a senior engineer working on backend platforms and distributed systems, currently owning payments, workflow orchestration, partner onboarding and document services on a large enterprise insurance platform at Aditya Birla Sun Life Insurance.

My instinct is to turn one-off implementations into platforms: a payment layer that adds new methods without a release, a configurable state-machine engine that replaced eight hardcoded modules, a partner-onboarding system that cut go-live from two months to two weeks.

I came into engineering through security — I hold an MSc in Cybersecurity Management from Warwick — so I tend to design for failure, idempotency and least privilege by default. Off the clock I'm building Argus, runtime observability for AI agents, and I've played competitive table tennis for thirteen years.

  • Promoted from SDE 2 to Senior Software Engineer I within 12 months on the back of platform ownership and delivery.

  • Designed a configurable XState workflow engine and migrated 8 hardcoded business modules onto it, cutting the effort for each new journey dramatically.
  • Built a partner-onboarding system that cut go-live from ~2 months to ~2 weeks; 4 partners live so far.
  • Own the quality bar: Snyk and SonarQube in CI, 90%+ coverage on new code, and observability in SigNoz. Mentor junior engineers through code and design review.

Things I'm building

Argus

In development

Source

Runtime observability for AI agents. Argus correlates agent actions — LLM calls, tool use, file I/O — with eBPF kernel traces, so you can see what an autonomous agent actually did at the syscall level, not just what it claimed to do. Node.js + TypeScript core, a Next.js dashboard, and a Python SDK.

  • TypeScript
  • eBPF
  • Observability
  • AI Agents
  • Python SDK

Momnts

Pre-launch

Live

A mobile-first hangout planner. Server-driven UI with calendar-overlap detection across Google and Apple calendars, so a group finds a time that actually works without the back-and-forth. React Native + Expo, Node.js/Express, PostgreSQL with Prisma.
