About this gig

Need a fast, reliable backend for your app, SaaS, or startup? I build clean, scalable REST APIs in Go, Python, and Node.js that are production-ready, not just "working code."


I'm a professional backend engineer with 2+ years shipping real systems: enterprise data platforms on AWS, Kafka, PostgreSQL, and Redis, plus open-source work merged into major projects like Envoy and Apache DataFusion. I was selected twice for Google Summer of Code and the Linux Foundation Mentorship Program.


What I can build for you:

  • REST APIs and backend services (Go / Python / Node.js)
  • - Database design and integration (PostgreSQL, MongoDB, Redis)
  • - Authentication, JWT, and secure endpoints
  • - Kafka / RabbitMQ pipelines and background workers
  • - Docker, Kubernetes, and CI/CD deployment
  • - Unit tests and clean, documented code

Why work with me:

  • Clear communication and honest timelines
  • - Clean, well-commented, maintainable code
  • - Source code and setup docs always included

Every project is different, so please message me before ordering so I can understand your needs and suggest the best package. Let's build something solid together!
