about me

Building things from every part of the stack.

Currently working on a rag-guided vector db solution for studying and learning cuda.

I'm an obsessive learner who's willing to pick up anything I or my team needs.

My values are for tech and software to improve lives and help everyone achieve their goals, no matter how.

If you are interested in talking with me or have a business inquiry, feel free to email me or reach out through LinkedIn.

Outside of work, you can find me stalking my A100 instance to see if my model has converged yet, planning and building desktop PCs, or biking in the city.
