What I'm looking for

I’m looking for a role where I can design and scale Go-based distributed systems end-to-end, partner with strong product teams, and prioritize observability, reliability, and long-term maintainability.

I’m a Senior Golang Backend Engineer with 8+ years of hands-on experience building distributed systems. I specialize in launching scalable high-load systems from scratch and scaling existing platforms, owning end-to-end development and architectural decision-making with a strong focus on scalability, reliability, and observability.

Across my roles, I’ve designed event-driven architectures and microservices that integrate synchronous and asynchronous workflows. I’ve delivered production improvements like reducing integration complexity and accelerating onboarding in a blockchain Digital Asset Platform, and building configuration-driven marketing and campaign systems that shift control to business teams.

I also lead migrations and modernization—such as a full-scale move from Java/Python/C++ to Go for unified maintenance, and implementing asynchronous notification pipelines using Kafka and Kubernetes to improve fault tolerance under peak loads. I bring strong engineering discipline through testing (including integration/mocks) and practical observability with Prometheus, Grafana, ELK, and Sentry.
