About

Hi — I'm Hólmsteinn.

Industrial engineer · operations research, data & AI-assisted development · Gothenburg

I like turning messy data and processes into things that actually run. I finished my BSc in Industrial Engineering at the University of Iceland in 2025 — and I've kept building ever since, more and more with AI.

Who I am

At Orka náttúrunnar (ON Power) I worked in the Technical Development team. My main project was a co-led rebuild of an engineering-drawings database of more than 30,000 documents, across internal teams and outside contractors — I wrote the document-processing scripts and the API-key integrations that connected the systems, and analysed resource flow through the Hellisheiði geothermal plant.

On my own time I build software and games end to end: a browser-based 3D dungeon-crawler in Three.js with its own level editor, a 300-piece modular asset kit and a character-animation system, plus a desktop "Command Center" productivity system over a markdown knowledge base. I build these increasingly with AI-assisted development using Claude Code, which has become one of the things I do best.

I moved to Gothenburg in 2026 and I'm studying Swedish. I'm looking for work in data, energy, or software and game development — ideally somewhere that cares about the people it builds for.

What I'm good at

Analytical engineer

Operations research & optimisation, simulation, forecasting, statistics and process analysis — turning data into decisions.

AI-assisted builder

I ship real software with Claude Code and agentic-LLM workflows — an edge that's becoming the way modern building works.

Fast study, end to end

I pick up new tools quickly (TypeScript, Three.js, Blender) and build the whole thing — editor, assets, animation, automation.

Experience & education

How I work

Craft over shortcuts

On anything meant to ship, I'd rather do it properly once than patch it forever.

Build for the people you build for

Player- and user-respecting design over quick or manipulative wins.

Make it actually run

End-to-end working systems, not slideware — from idea to something you can use.

Stay a fast learner

The tools keep changing; I keep picking them up. Curiosity is the constant.

Languages

Icelandic — native English — fluent Swedish — A2, working toward B1
