## About

“Technology is best when it brings people together\.” – Matt Mullenweg For over 18 years, I have built and led technology platforms across Bryt, Microsoft, Amazon, Barclays, Adobe, and Microsoft, moving from hands\-on work to engineering leadership across AI\-native systems, cloud infrastructure, SaaS platforms, and enterprise\-scale products\. In the last few years alone, I have reduced infrastructure OPEX by 35%, accelerated feature time\-to\-market by 40%, achieved 95%\+ semantic match accuracy for personalized tutoring, and tripled daily active engagement by building AI\-native education platforms at Bryt\. Earlier, I supported contact management infrastructure that served 700M\+ daily active users, reduced operational costs by \~$150M, cut MTTD/MTTR by 45%, increased customer conversions for Amazon by 15%, and reduced COGS by 20%\. Today, I am committed to helping organizations turn modern architecture, AI\-native thinking, and high\-performing engineering teams into resilient platforms that can support growth, reliability, and long\-term product advantage\. If you value engineering leadership that connects technology depth with business outcomes, I would welcome the conversation\. 📩 abhishek\.bswas@gmail\.com
