I build backend systems with a focus on clarity, correctness, and long-term maintainability.

About Me

I write backend code and design systems where frameworks are optional, but architecture, data structures, invariants, and correctness are fundamental. My main interests revolve around how real systems behave:

• data flows and lifecycle boundaries
• state isolation and consistency
• transactions, queues, caching
• API design and system invariants
• service interactions and failure modes I work primarily with Python, PostgreSQL, Docker, Linux, and the ecosystem around reliable backend engineering. I focus on depth rather than breadth — fewer tools, deeper understanding.

Engineering Principles

- reduce surface area  
- predictable data flows  
- explicit boundaries  
- no hidden state  
- architecture as a tool, not decoration  
- systems that remain readable years later
