I design and build backend systems: event-driven services, IoT platforms at ~1M-device scale, and LLM agents that ship.

What I've shipped
- 8+Years in software engineering
I build systems that turn messy, high-volume problems into reliable pipelines: a million-device IoT platform, a Kubernetes migration, and now AI agents that test real software end to end.

What I build, and why
I build systems that turn messy, high-volume problems into reliable pipelines: a million-device IoT platform, a Kubernetes migration, and now AI agents that test real software end to end.
I'm Abdullah Hamza. You can call me Abu.
I'm an AI Agent Engineer at Openprovider, based in Colombo, working fully remote since July 2026. The main thing I build there is an autonomous QA agent. It reads a Jira ticket and the code behind it, generates test cases, explores the feature in a real browser on staging, and has an LLM judge decide pass or fail with cited evidence.
Before that: eight years across four employers, never in the same domain twice. At Zone24x7, I built an IoT and remote-monitoring platform running on around a million retail devices, along with its SDKs and the monitoring agents that shipped on the devices. At TrueStory, I got promoted from Senior Backend Engineer to Tech Lead in six months and led the company's move to Kubernetes. At Understory, I architected event-driven booking infrastructure on AWS and built an LLM-powered lead-sourcing engine that processed 1.3 million websites.
I also build things of my own, end to end: Al-Hadra, an Islamic home hub product, and MakkahMadinahGuide.com, a freelance client build for a US client.
I'm T-shaped on purpose: deep enough in backend and infrastructure to own hard problems alone, broad enough across product, data, and delivery that handoffs don't stall. I use AI agents daily and build them for a living, but I don't treat them as autopilot. Judgment on system boundaries, failure handling, and what ships stays mine, including the agent answering questions about me on this site.
