About

Full-stack engineer with 4+ years building and scaling production SaaS at YC-backed startups (Peakflo W22, Atri Labs W23) and enterprise compliance platforms (Sprinto). At Sprinto, I’ve been building revenue-critical compliance and workflow systems used by enterprise customers. My work includes: - Owning and evolving a rule engine used by 5+ internal teams, which enabled customer configurations to be shipped 14× faster (days instead of weeks) - Shipping deal-blocking features that helped close $50k+ enterprise contracts - Delivering 5× query performance improvements and production-grade feature-flag caching - Owning core workflows across tasks, evidence, audits, and vendor Before that, at Peakflo (YC W22), I built and scaled the company’s payments and billing platform, including: - A Travel & Expense (TnE) product that opened a new revenue line - Multi-tenant payment and billing systems supporting thousands of users per customer - Refactoring tightly coupled billing logic into independent, scalable services Earlier, at Atri Labs (YC W23), I worked on the product platform itself — building a UI framework, state machines, and component systems used by customers to ship production websites. I specialize in React, Next.js, Node.js, GraphQL, PostgreSQL, Redis, and MongoDB, and I thrive in 0→1 and scale-up environments where engineers own real business outcomes, not just tickets.
