About

A modular, maintainable approach

I like building systems that are easy to evolve: reusable components, consistent layout primitives, and clear information architecture.

Principles

Reusable blocks, predictable spacing, and clear hierarchy.

Focus

Backend APIs, performance, and developer experience.

Collaboration

Shipping with speed while staying readable and testable.

Skills

Core skills

Golang backend engineering, Kubernetes operations, and performance tuning.

Infrastructure & Orchestration

Kubernetes, Docker, AWS (EKS/EC2/SNS/SQS), Helm, Terraform, Ansible.

Distributed systems (Golang)

Microservices, async messaging (SNS/SQS/RabbitMQ), caching (Redis), observability and incident response.

CI/CD & Security

GitOps (ArgoCD), Bitbucket/GitLab CI/Jenkins, dependency scanning (BlackDuck), secrets management.

Add documents to the Firestore collection works with title, description, thumb, and repo_uri.

Freelancing

Have an idea? Let’s ship it.

If you’re building a product or need backend help, send a quick request — I’ll reply with a plan and timeline.

What you can request:

  • Backend APIs & microservices (Golang)
  • Kubernetes / EKS deployments + GitOps
  • Performance & reliability improvements
  • Async pipelines (SQS/SNS/RabbitMQ) + Redis caching

Quick start

Share scope + timeline + budget range.
