Enjoying AI Revolution
Hi, I'm AI Sarker
General Manager, Technology at Arogga with 16 years designing, building, and scaling digital platforms across health-tech, government, and telecom — now building applied AI and Rust systems hands-on.
About Me
Engineering leader who scales platforms
I'm Md Aminul Islam Sarker — General Manager, Technology at Arogga Ltd, Bangladesh's leading health-tech platform. I own technology strategy, architecture governance and engineering culture across backend, mobile, ERP and infrastructure teams — steering the platform through 831% growth to 2M+ users while holding 99.99% uptime.
I was a core contributor to Bangladesh's National Portal Framework powering 25,000+ government websites, recognized with the WSIS Prize (ITU, 2015) for digital transformation. I've trained 1,000+ government officials and built multi-functional engineering teams from the ground up.
Alongside the day job I still build production systems myself — a social and video platform in Rust with a hybrid recommendation engine, event-driven media transcoding and ONNX-based ML workers. I'm comfortable operating from technology strategy down to system design.
