Taking new projects · Bangladesh, US & Australia
I'm Ruhan Islam, an AI automation engineer. I build private AI, workflow automation, backups that actually restore and monitoring that warns you first — self-hosted on proven open source and supported after launch, for businesses in Bangladesh, the US and Australia.

Forecast: disk full in ~6 days — alert sent
Six problems I solve. Each one runs on infrastructure you own and is built on proven open source — no per-seat fees, and nothing quietly leaves your network.

Self-hosted systems from my own lab, a US software company and national government platforms. Public-sector clients are described, not named.
Own product · Backup
The problem: small offices pay for cloud backup and still lose work when a PC dies. What I built: an agent that encrypts files on their owner's PC, splits them into erasure-coded shards and stores them on the other PCs in the office — no central server, and every restore is verified by hash.
Own product · Monitoring
The problem: outages found by users, disks found full. What I built: agents for Windows and Linux, checks for databases, DNS and services, an alert engine that learns each server's normal and forecasts trouble, and a maintenance calendar that silences planned work.
US software company · AI
The problem: reports assembled by hand from scattered files. What I built: upload the documents, describe the report, and a multi-turn AI agent writes it using retrieval over a vector index — routing work between OpenAI and Gemini to keep costs down. Promoted to team lead during the engagement.
Government · National scale
What I built: time-gated exam paper delivery to centres nationwide, a tamper-evident results archive going back to 2000, and a 10-service logistics platform on Kubernetes with continuous delivery — plus security hardening of four legacy exam systems.
A remote engagement built for small teams: you always know what's being built, what it costs and who to call.
A private consultation, then a written plan: what to build, what it replaces and a fixed price.
Working demos every week on your own infrastructure, so you can change your mind while it's still cheap.
Monitoring, tested backups and updates after launch, with response times in writing — or a clean handover to your team.
