9+ years crafting backend systems and platform engineering. Currently processing $40B+/year in payment transactions at Zyl Labs — formerly scaled ATOM Store to 330M+ requests/day.
Beyond backend engineering — I build consumer products under kernelU. Explore my apps and games.
Productivity tools and fintech utilities built for everyday users. Crafted with the same precision I bring to enterprise systems — but packaged for your pocket.
Mobile games designed for fun and flow. Built on lessons learned from scaling gaming microservices to millions of daily active users.
Personal finance app for tracking spending, managing budgets, and growing your wealth. Local-first, biometric-secured, beautifully designed.
Libraries like escalite (API log collector), shondesh (notification channels), and pysentinel (threshold-based alerting) — built to scratch real engineering itches.
From payment gateways to gaming microservices — these are the tools I rely on.
Occasionally I write about what I've learned building high-throughput systems, leading teams, and shipping consumer apps.
Lessons from processing $40B in annual transactions — what breaks, what holds, and what nobody tells you in textbooks.
A practical walkthrough of the CI/CD setup that transformed how our team ships — from hours to minutes.
Honest reflections on team leadership — the sprint rituals that worked, the ones that didn't, and the lessons in between.
I'm based in Dhaka, Bangladesh (UTC+6) and open to remote consulting, collaboration, or just a good conversation about backend systems and product development.
