Hey, I'm a Go Backend Engineer 👋

Backend engineer focused on building reliable distributed systems, internal platforms and high-performance services with Go.

I work with microservices, event-driven architecture, PostgreSQL, gRPC, messaging systems and observability. I enjoy solving problems around concurrency, distributed workflows, API design, performance and infrastructure.

Currently exploring cloud-native systems, serverless platforms, developer tooling and open-source contribution.

🚀 What I work with

Backend

Go gRPC REST API Echo

Databases & Storage

PostgreSQL Redis ClickHouse MinIO

Messaging & Distributed Systems

Kafka NATS JetStream

Infrastructure

Docker Google Cloud Cloud Run GitHub Actions

Observability

OpenTelemetry Jaeger Prometheus

🧠 Areas of interest

  • Distributed systems and microservices
  • High-load backend architecture
  • Go concurrency and runtime internals
  • Event-driven systems with Kafka and NATS JetStream
  • PostgreSQL performance and data modeling
  • Authentication, LDAP and identity systems
  • Observability with OpenTelemetry
  • Serverless and cloud-native infrastructure
  • Developer tooling and open-source software

🛠 Selected engineering experience

  • Designing Go microservices using Clean Architecture
  • Building gRPC and REST APIs
  • Working with PostgreSQL transactions, complex queries, indexes and EAV data models
  • Designing asynchronous communication with Kafka and NATS JetStream
  • Building LDAP-compatible authentication and directory integrations
  • Implementing distributed patterns such as worker pools, pipelines, circuit breakers, bulkheads and Redis-based rate limiting
  • Building observability pipelines with OpenTelemetry, tracing and profiling
  • Deploying Go services to Google Cloud Run
  • Working on backend systems involving real-time audio processing, telephony and gRPC streaming
  • Contributing to open-source Go projects and exploring improvements in popular Go frameworks

🔬 Currently building

FuncWarm

A Go-based control plane for reducing serverless cold starts and balancing latency against infrastructure cost.

Technologies:

Go · PostgreSQL · Cloud Run · OpenTelemetry · Docker

Focus areas:

  • automatic warm-up scheduling
  • latency analytics
  • cold-start detection
  • cost optimization
  • support for serverless and Knative-style workloads

🤝 Open to

Interesting backend and distributed systems projects, open-source collaboration and engineering challenges involving Go, cloud infrastructure and high-load systems.

Build simple systems. Understand complex ones.
