## Previous work

- Software Engineer, contract, Supercell AI Lab, 2026. Simulation and internal
  playtesting tooling.
- Software Engineer, Sensofusion, 2025. Counter-UAS, hardware-in-the-loop and
  software-defined-radio validation systems.
- Research Assistant, King Abdulaziz University Department of Biomedical
  Engineering, 2022 to 2024.

## Open-source engineering

Ijtihed has merged pull requests into NumPy, SciPy, TensorFlow, Node.js, OpenCV,
Godot, ArduPilot, Docker Compose and IPython. The recurring themes are numerical
correctness, silent wrong-answer bugs, reliability and performance.

Representative work includes fixes for NumPy in-place aliasing and infinite
endpoints, SciPy signal-processing and integration edge cases, TensorFlow byte
order normalization, Godot rendering and engine APIs, OpenCV lock contention,
Docker Compose publishing behavior and IPython argument parsing.

## Selected projects

- ps2-forge: a small C engine for making real PlayStation 2 games, plus a CLI
  that scaffolds, builds, boots and headlessly tests projects.
- sandengine: a GPU falling-sand cellular automaton in Rust, wgpu and WGSL.
- triple_pendulum.asm: a chaotic triple-pendulum solver in x86-64 assembly.
- driftmd: a CLI and CI tool that checks README claims against a repository.
- oChess: chess with engine analysis and mistake-driven spaced repetition.
- Schema: an AI-native architecture graph and codebase editing environment.
- RAGTAG: citation-backed GraphRAG over Finnish tax law.

## Education and teaching

- Aalto University, Computational Engineering studies with a theoretical
  computer-science minor.
- Aalto University, MSc Mathematics in progress, with interests across applied
  physics and machine learning.
- Bachelor's thesis: “Tasks, Methods, and Evaluation in Physical Human–Robot
  Collaboration: A Structured Review.”
- University teaching in software engineering, software testing, software design
  and modelling, and complex systems.

## Research
