Performance, maintainability, security: no emotion, no theory. Just logic, written to last.
Fluent across the entire field.
Understanding the whole stack means I see the best way to build the app. Not just the code.
Software Engineering
Full-stack systems in Python with handwritten front-ends — from APIs and databases to the interface itself. Built to be fast, readable and maintainable for years.
