## About

I'm a software engineer at [Interview Kickstart](https://interviewkickstart.com) working on payments — gateway integrations, installment billing, and the flow that grants learners access after they pay. Previously at [Instahyre](https://instahyre.com) I built distributed systems, search infrastructure, and optimized backend performance. Before that I built event-driven pipelines and SSR frontends as a [full-stack contractor](/#work). I hold a degree in [Electrical & Electronics Engineering from NMIT Bengaluru](https://nmit.ac.in) and have authored [IEEE research papers on Quantum Computing](https://scholar.google.com/citations?user=q3MbjLQAAAAJ&hl=en). I like working across the stack — from Redis locking to Elasticsearch query parsers to Next.js SPAs.

## Work

### [Interview Kickstart](https://interviewkickstart.com) — SDE-1

Bengaluru, India. June 2026 – Present

- Fixed 5 payment-gateway defects against the live API format, stopping real transactions from silently falling back to a backup provider
- Fixed a double-counting bug in installment balance logic that was silently rejecting valid payments
- Shipped a feature-flagged payment-flow rewrite with old and new systems running side-by-side for instant rollback
- Cut learner activation delay by granting access on payment completion, with a 30-day auto-revoke if payment is never confirmed
- Cut error-monitoring noise by ~30% by filtering expected no-ops, and added reference-ID logging for faster debugging

### [Instahyre](https://instahyre.com) — SDE-1

Bengaluru, India. December 2024 – May 2026

- Designed Redis-based distributed locking (SETNX + TTL) to eliminate double-booking under concurrent traffic
- Reduced API latency by 80% (p75: 600ms → 120ms) by profiling slow PostgreSQL queries and optimizing payloads
- Built a stack-based boolean query parser (AND/OR/NOT) for Elasticsearch, improving matching relevance by 20%
- Reduced regression bugs by 30% by decomposing a monolith into independently maintainable modules

### [Freelance Work](https://upwork.com) — Full-Stack Developer

Remote. May 2024 – August 2024

- Designed an event-driven pipeline using Kafka for asynchronous order processing across thousands of daily events
- Implemented idempotent webhook-based payment confirmation, reducing duplicate order processing by 95%
- Improved Core Web Vitals by 35% with a Next.js SSR architecture optimized for first-contentful paint and reduced JS bundle size
