About
Backend engineer with 9+ years of experience designing, building, and operating distributed systems at scale. I focus on reliability, performance, and clean architecture. Currently leading the payments platform team at RippleFlow, where I drive the migration from monolithic services to event-driven microservices processing over $2B in annual transaction volume. Passionate about observability, system resilience, and mentoring engineers.
Experience
Senior Backend Engineer RippleFlow
Jan 2021 – Present- Architected and led migration from a monolithic payment engine to a domain-driven event-driven architecture using Go, Kafka, and PostgreSQL, reducing payment processing latency by 40% and enabling independent service deployments.
- Designed a fault-tolerant idempotency layer handling 12,000+ transactions per second with 99.99% uptime during peak shopping events.
- Built a real-time fraud detection pipeline using streaming analytics, reducing false positives by 28% while maintaining detection rates.
- Mentored 5 junior engineers through structured code reviews, pair programming, and internal tech talks on distributed systems patterns.
Backend Engineer VaultData
Jun 2017 – Dec 2020- Developed and maintained a high-throughput event ingestion service processing 50M+ events daily, serving as the backbone for real-time analytics products.
- Reduced infrastructure costs by 35% by optimizing query performance in PostgreSQL and implementing automatic sharding and partitioning strategies.
- Designed a gRPC API layer for internal microservices, cutting inter-service latency by 60% compared to the previous REST-based approach.
- Led the adoption of Kubernetes and Helm charts for deployment, reducing release cycle time from 2 weeks to 3 days.
Software Engineer Nextera Systems
Aug 2014 – May 2017- Built and maintained RESTful APIs for a fleet management platform serving 200+ enterprise clients, handling 2M+ requests daily.
- Implemented a distributed job scheduler using Redis and RabbitMQ, improving task reliability from 92% to 99.7%.
- Wrote comprehensive integration tests and contributed to CI/CD pipeline improvements, increasing deployment frequency by 4x.
