About

It has been a great learning experience till now. Business and technology are complimentary. Providing excellent customer experience is crucial. I started with Microsoft where I learned about importance of communication between mission critical components. Next, I joined Amazon Endless/Javari, Retail Expansion group's fashion apparel division, started in `07. Team owned endless.com, javari.co.uk, javari.jp, javari.de and javari.fr multi-tenanted stack. Endless was later absorbed for Amazon Fashion. I learned and embraced Amazon's leadership principles. Then, I joined Airpush, competitor to OpenX and Inmobi. Airpush SDK is available for major mobile platforms. I learned about importance of high performance computing and frugality where a 4 core, 4GB machine can serve ~24k RPS with the right tools and good domain understanding. Next, I joined TFS which was later acquired by OLA. OLA bridges the demand and supply gap between customers and drivers. I learned about serving indian customers at OLA. Then, I joined Target. Target teaches Love, Value and Respect for each individual (employee or customer). Next, I worked in VISA as Staff Engineer working in VISA Direct Payment team. Then, I worked in Walmart Global Tech as a Staff Engineer.
