About

CS grad. Software architect by profession. If I weren't a software dev, I would be struggling to become one. Currently enabling fintech using cloud computing at Bajaj Capital. I always try to focus on solutions rather than technologies. Obsessed with architecting and studying systems built at huge scale. An avid explorer of serverless computing. I think it has immense potential in future. Always focused on becoming an active contributer rather than a passive one. Reach out to me if you want to discuss anything related to tech. Email - aayush.sahgal95@gmail.com Other than my software dev role, I am a die hard Barcelona fan. Reddit, memes, urdu and random youtube videos also help me escape.
