About

I’m a Software Engineer focused on building scalable, fault-tolerant backend systems and distributed infrastructure that perform reliably at high scale. Currently, I work on high-impact systems handling billions of records and real-time workloads. I’ve led the design of large-scale data migration pipelines (1.5B+ records) with zero downtime, built event-driven architectures to replace brittle batch jobs, and engineered low-latency systems processing 100K+ records/sec. My core strength lies in solving hard backend problems — data consistency, system reliability, and performance at scale. I enjoy taking ownership of complex systems end-to-end, from architecture to production, with a strong focus on observability, resilience, and clean design. I’ve worked extensively with: • Distributed Systems & Microservices • AWS (KMS, DynamoDB, Lambda, S3, CloudWatch) • Java (Spring Boot), Go • Redis, PostgreSQL, MySQL • Event-driven systems & fault-tolerant pipelines Beyond work, I like building systems from scratch — including a payment orchestration engine with strong idempotency guarantees, retry strategies, and observability baked in. I’m always interested in backend and distributed systems roles where I can work on high-scale infrastructure and solve meaningful engineering problems.
