How I Work

I turn ambiguous requirements into working systems. Strong focus on understanding the problem before writing code, designing clean abstractions, and making databases fast.

What I Do

  • • Translate business needs into technical solutions
  • • Design APIs and system abstractions
  • • Optimize slow queries and bottlenecks
  • • Build maintainable backend systems

Tech Stack

Backend:

Go, Python, Django

Frontend:

React, Tailwind CSS

Data:

PostgreSQL, Redis

Infra:

Docker, Linux, CI/CD

Approach

  • • Understand the problem deeply before coding
  • • Optimize with data, not guesses
  • • Write code that others can maintain
  • • Keep systems simple until complexity is justified
