About Me
I'm a Senior Software Engineer with expertise in building scalable microservice architectures and leading technical teams. Currently at Memorial Sloan Kettering, I've led the design and development of 18+ APIs that have significantly increased our client base and improved accessibility to critical cancer research.
With a Master's in Computer Science from Harvard University and experience at major companies such as JPMorgan Chase, and Factset Research Systems, I bring a strong technical foundation combined with leadership skills.
