About

Startup engineer who owned an end-to-end carpool marketplace experience at FavorIt (React Native, Firebase/Firestore, Cloud Functions, Stripe) and iterated rapidly using Mixpanel + feature flags while applying rigorous integrity controls for booking and payments. Also built a TypeScript/React + Go/Postgres workout tracker and previously worked on Spring Boot microservices for financial-institution workflow automation with event-driven patterns (outbox, idempotency, backpressure tuning).

Key Strengths

• Owned and shipped end-to-end customer-facing mobile product (React Native + Firebase + Stripe) from design to production
• Data-driven iteration using Mixpanel funnels/logs and feature flags; shipped updates every few days and improved conversion by simplifying high-dropoff forms
• Strong payments and data-integrity engineering (idempotent operations, transactional booking, Stripe test-mode E2E tests)
• Solved concurrency/race conditions with state-machine redesign, Firestore transactions, and stress testing
• Designed scalable full-stack architecture (TypeScript/React feature-based frontend; Go layered backend over PostgreSQL)
• Microservices/event-driven architecture experience (Spring Boot services, outbox pattern, consumer scaling, backpressure tuning, versioned event contracts)
• Built and drove adoption of an internal ops/support dashboard; reduced ticket resolution time and engineer interruptions via self-service tooling
