About Me

I specialize in web design, graphics development, and programming for artists and creative professionals. My focus is on crafting tools that merge technical precision with artistic freedom — clean, efficient code that feels like an extension of the creative process rather than an obstacle.

Over the past 25 years, Linux has been my primary environment — a space where I honed my skills and built a deep respect for open-source software. Recently, I’ve embraced a more flexible, cross-platform workflow, integrating both macOS and Windows 11 into my toolkit. I never expected to appreciate Windows, but thanks to Chris Titus’s Windows Utility — which helped me remove unnecessary bloat and tailor the system to my needs — it’s become a surprisingly capable and efficient part of my setup.

Languages I love working with:
Python · JavaScript · PHP
