At FINMO, I design and ship NestJS REST APIs serving 5K+ daily requests, build real-time alerting systems, and improve high-traffic PostgreSQL endpoints for 10K+ users.
I've reduced query execution time by 30%, modelled 15+ Cube.js business metrics that improved decision-making speed by 50%, and built a Kafka retry pipeline that achieved 99% reconciliation success with almost zero data loss. I also set up Jenkins CI/CD with Jest testing, lifting coverage above 80% and reducing production incidents by 40%.
Outside of work, I've built a multi-tenant SaaS platform with subscriptions, 2FA, live chat, and audit logs; an AI chatbot for 50+ simultaneous users; and a laptop search engine processing 2,000+ listings.
