Senior Software Engineer · Bangladesh
I build reliable systems — and write about how they actually work.
Full-stack .NET, Angular and Azure for the Swiss insurance market. After hours: a self-hosted AI agent, a homelab, and a couple of products. Eight years in, hands-on, no architecture-astronaut act.

Why I rebuilt abdunnahid.com — and what I plan to write about: software engineering, AI agents, and running a homelab in the open.

Things I build & run
Hermes — Personal AI Agent
An autonomous agent that helps run my homelab and my writing.
A self-hosted AI agent with skills, scheduled jobs, long-term memory, and human-in-the-loop approval. It researches, drafts, and helps operate the homelab — and powers the content pipeline behind this site.
Homelab
20+ self-hosted Docker services across two machines.
A self-hosted infrastructure running media, photos, automation, monitoring, DNS, reverse proxy, and more — managed as independent Docker Compose services with a documented architecture. Where I learn infra, networking, and self-hosting by running it for real.
MyBikes.App
A mobile app I designed, built, shipped, and maintain solo.
Owner and sole developer of MyBikes.App — from product design through development, publishing to the Play Store, and ongoing maintenance. A end-to-end product built and run by one engineer.
