About me

Building software with curiosity and purpose.

Software Engineer

Building & exploring

I'm a software engineer who enjoys turning ideas into well-designed, reliable software. I work across the stack, with a particular interest in backend systems, developer tools, and artificial intelligence.

I like understanding how things work beneath the surface — from designing APIs and databases to experimenting with programming languages, machine learning systems, and developer-focused products.

I'm constantly building and experimenting with new ideas, using projects as a way to explore technologies and deepen my understanding of computer science.
