Kieran van der Heijde K Python Engineer @ Veldhoven, NL

Software by profession,
engineer by obsession.

I'm a believer in keeping things simple. I like taking complex ideas and turning them into products that are robust, fast, and genuinely good to use. Mostly in Python, usually with Flask or FastAPI.

Experiments

Bouncer

Research prototype

A filtered Spotify Jam: guests request songs, the host writes a plain-language vibe ("keep it energetic, no rap") and an LLM-driven filter decides what reaches the queue — track embeddings scored against the prompt, with an LLM judge on the borderline cases. 95.2% on a 963-track eval set. An honest work-in-progress into how far cultural knowledge can stand in for audio features.
