Short Profile

coding mantra

Code like no one's watching.
Deploy like everyone is.

Don't overthink it. Start messy, refine ruthlessly. The best code solves real problems for real people. Everything else is just noise.

Interested in the code?

Most of my projects involve proprietary algorithms and sensitive data. I'm happy to discuss the technical details, share code samples, or walk through the architecture.
