What I'm looking for

I’m looking to build high-availability backend platforms with event-driven architectures—partnering with teams that value clean architecture, secure multi-tenant design, and production reliability through observability and root-cause-driven improvements.

I’m a Senior Backend Engineer with 3+ years delivering high-traffic, fault-tolerant backend systems using Java, Spring Boot, and event-driven architectures. I’ve worked on transaction-sensitive platforms across e-commerce, lottery, and security AI, with hands-on experience designing Kafka-powered pipelines and concurrency-safe services.

In my current role as Lead Backend Engineer at Udala Solutions, I architect high-concurrency Java + Spring Boot services for thousands of concurrent transactions, implementing producer/consumer patterns to improve responsiveness and reduce coupling. I also perform root-cause analysis on production incidents and ship long-term fixes that measurably improve stability and reduce error rates, while leading code reviews and mentoring on clean architecture, data consistency, and fault tolerance.

Before this, I built backend systems on contract engagements—from AI-powered security agents using NestJS and TypeScript to compliance-aware audit logging and messaging patterns. Across projects, I’ve focused on secure multi-tenant designs, reliable infrastructure automation (Terraform, Docker, CI/CD), and cloud deployments on GCP and AWS, aligning my work with high-availability, distributed-systems principles.
