Readme
I am a Full Stack Engineer with a Bachelor’s and Master’s degree in Computer Science. I have full time experience across the end to end lifecycle, including DevOps, frontend, backend, and system architecture. I have built backends that integrate machine learning models and architected scalable systems using a variety of technologies such as NestJS, FastAPI, Spring Boot, SQL, Redis, MongoDB (Vector Search), Docker, AWS, and Google APIs. I have full time experience collaborating with data scientists, designers, and frontend developers to move projects into production. I love learning new things and prioritize understanding them in detail. To stay organized, I use Obsidian for note-taking and documentation. My personal interests include neurology, philosophy, physiology, and computer science.
