Started My career on building first venture capital market survey of US on top of huge survey firms data. That was a time when Mapreduce paper was not published, and running applications on 128 GB RAM used to be a big problem. Later also worked on Googles Mapreduce team, to create complex pipelines on top of huge Gmail, Docs, Calendar etc Google Apps Logs. Worked many fullstack application development on Java/J2EE space. One of the key focus is identifying customer pain points, and building small MVPs to solve it, and architecting in a way that easy incremental improvement is possible on top of it, with domain driven principals and microservice architecture.
