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
