About

I build backend systems that scale — cleanly, reliably, and fast. Currently working on distributed systems and analytics infrastructure at Hivel, where I've redesigned DB schema, reduced API latency from 60s to under 10s at enterprise scale, and stabilized production systems across GraphQL, caching, and JDBC layers. Before this, at Zeta, I built microservices from the ground up — Kafka-based event pipelines, JWT-secured API gateways, Redis caching strategies, and CI/CD with Docker and Jenkins. I care a lot about code quality; I've shipped features with 95%+ test coverage using JUnit and Mockito. My stack: Java, Spring Boot, Kafka, PostgreSQL, AWS, Docker, Redis, Vue.js. I enjoy hard backend problems, high throughput, low latency, distributed consistency. If you're working on something in that space, I'm always open to a conversation.
