About · Who I am
Practical software, crafted with intent.
I'm a full-stack developer who thrives on building practical, well-crafted web applications. My focus is on clean architecture, performant backends, and intuitive user interfaces.
I work primarily with Python and TypeScript, building everything from employee management systems to bank statement converters — tools that solve real problems for real users.
Every project follows the same philosophy: think before coding, get it right on the first pass, and never ship something I wouldn't use myself.
