I’m a Senior Backend Engineer specializing in high-throughput distributed systems, performance optimization, and production reliability.
I’ve built and scaled backend systems handling up to 2M requests per minute, with a strong focus on latency reduction, fault tolerance, and observability.
Key highlights:
- Reduced API latency by 70% on critical payment workflows
- Scaled 20+ APIs with high concurrency using Redis caching and optimized queries
- Cut production incidents by ~90% through improved logging and observability
- Designed and maintained microservices architectures on AWS (Lambda, SQS, DynamoDB, etc.)
Tech focus: Go, Node.js, .NET, distributed systems, event-driven architecture, AWS, Kubernetes, Redis, SQL/NoSQL
I’m particularly interested in:
- Backend/platform engineering roles
- Systems operating at scale
- Teams that value clean architecture and engineering rigor
Open to remote roles globally and relocation opportunities with sponsorship.
