What I'm looking for

I’m open to remote work where I can build and scale backend services in Go, improve performance and search quality, and own reliable integrations with strong observability and modern infrastructure.

I’m a Backend Developer with 3+ years of commercial experience building scalable services in Go. I focus on REST API and gRPC design, microservice architecture, and high-load system development, delivering measurable improvements in performance, search quality, and onboarding.

Recently, I worked on a backend service for an online hotel booking platform, migrating from monolithic architecture to SOA, improving search ranking with Elasticsearch, and optimizing MongoDB/PostgreSQL queries. I’ve also built Kafka-driven integrations for real-time price and availability updates, supported Docker/Kubernetes deployments with Helm, and used Prometheus/Grafana for observability—cutting search response time by ~40% and reducing new partner onboarding from ~2 weeks to a few days.
