About this gig

Are you building a backend system that needs to be fast, reliable, and production-ready?


I'm a backend engineer with 4+ years of professional experience building high-performance services in Go (Golang) and Java. I specialize in systems where performance and memory efficiency actually matter not just CRUD apps, but real workloads.


What I can build for you:

REST and gRPC APIs in Golang or Java (Spring Boot)

High-throughput, memory-optimized micro-services

PostgreSQL schema design, query optimization, and indexing

System-native applications with low latency requirements

OpenTelemetry instrumentation and observability pipelines

Kubernetes-ready services with proper health checks and configs

GCP integrations (Cloud Run, Pub/Sub, GCS, IAM)

API gateway integrations (Kong, Apigee)


My background includes building OpenTelemetry collector components, ANTLR-based query parsers, Terraform-automated GCP infrastructure, and API gateway systems at scale all in a professional cybersecurity product environment.


Why work with me:

I write clean, idiomatic Go and Java no copy-paste code and ensures Test coverage, performance and understandable by other Developers
