Things I made
to solve problems
I ran into.

Each project started with a recurring problem. Here is what it solves, what came out of it, and where to try it.

01
Learning system

Spanish learning system

Problem
Regular Spanish practice needs short sessions built on useful sentences rather than long, fixed courses.
Outcome
A trainer of about 5–8 minutes that saves progress for invited learners and offers an unsaved guest preview, plus speaking, reading, and listening activities, a local video/subtitle player, and a 50-card browser deck.
Contribution
Sondre directs the product: goals, priorities, and review. Implementation is done with Claude, an AI coding assistant, coordinated by the Hermes agent.

02
Utility suite

Engineering and study toolkit

Problem
Recurring coursework calculations are quicker and easier to check with transparent, unit-aware tools.
Outcome
A unit converter for SI, imperial, and oilfield units, and calculators for Darcy–Weisbach pressure loss, hydrostatic pressure, ideal-gas volume, NPV, and payback with the formulas shown. Intended for study and checking, not operational decisions.
