About

Calm backend engineering for real production work.

I build APIs and backend services with a focus on clarity, performance, and maintainability.

Full-time at Sportisimo, I work on backend services and integrations used in real traffic. I prefer pragmatic solutions that stay readable for teams and stable after launch. My approach focuses on proper architecture patterns, efficient database design, and continuous delivery.

Architecture

Clear boundaries, predictable code, and decisions that scale.

Performance

Query-aware work with attention to response time and cost.

Delivery

Static analysis, tests, and workflows that keep shipping quality under control.

AI Development

LLM-assisted engineering in daily practice.

I actively integrate AI tooling into backend development — from code review to agentic workflows that accelerate the entire dev loop.

Daily Workflow

Using LLMs for code review, debugging, and drafting solutions faster without sacrificing code quality or ownership.

Architecture & Planning

Leveraging AI for design decisions, trade-off analysis, and documentation that keeps teams aligned and systems maintainable.

Agentic Tooling

Claude Code, MCP-connected tools, and multi-step agent workflows integrated directly into the development loop for real productivity gains.

  • Claude API
  • MCP
  • Agentic Workflows
