What I'm looking for

I seek a hands-on leadership role where I can modernize backend platforms, mentor teams, and deliver scalable, high-performance systems in an agile, collaborative environment.

I am a results-driven Backend Technical Team Lead and Senior Software Engineer with 15+ years building and scaling high-traffic platforms across e-commerce, fintech, and enterprise domains. I combine hands-on engineering with technical leadership to deliver measurable business outcomes.

My work includes modernizing legacy systems into resilient microservices, improving order throughput by 440%, achieving sub-100 ms product search latency with Elasticsearch, and increasing transaction success rates under load by 18%. I design systems end-to-end — from architecture and infrastructure to production-grade code and deployments.

Technically, I am proficient in .NET Core, Golang, Elasticsearch, Kafka, RabbitMQ, Kubernetes, and Clean Architecture, and I focus on performance tuning, fault tolerance, observability, and CI/CD. I also introduced AI-assisted development practices that increased sprint velocity by 10% and enforced code-quality frameworks that reduced production defects by 15%.

I am a strong collaborator and mentor who supports team growth, enforces engineering best practices, and takes ownership from concept to production to deliver scalable, reliable, and business-impactful solutions.
