I'm a UNIX systems and network programmer at heart. Currently specialized in backend dev, AI/LLMs and operations. I like writing CLI and server applications. I contribute to many open source projects and am comfortable working with decentralized teams.

I have 15+ years experience in software development spanning SysAdmin/DevOps, IT Architecture, OpSec, and LLM/ML/Deep Learning. I've honed my skills in both backend and frontend dev using languages such as Golang, Python and C and recently Rust.

I've gained experience over the years in a broad range of software projects with clients ranging from big companies to small startup teams spanning many countires. My problem solving abilities and social skills makes me particularly adept at working on the ground floor of projects with distributed teams where things move fast.

Whether it's specifying and designing software stacks, prototyping an MVP with with esoteric technologies, or just giving advice or an extra hand while styaing out of the way, I'm always up for a challenge.

In the recent years I developed a strong interest in AI and Deep learning with a particular focus on LLM and diffusion models.
