About Me

Software Engineer. Music and Photography Hobbyist.

I am a pre-med student turned software engineer with a boundless passion for all things technology. Bioinformatics research introduced me to writing software and I haven't stopped coding since.

I'm always looking for a difficult problem to solve and I'm always eager to learn a new technology to add to my toolset. Currently fascinated with scalability and the collection, processing, aggregation, and serving of big data.

Shoot me an email if you'd like to talk about software, technology, job opportunities, or music.
