Will Tonkin

I’m Will 👋 — a thoughtful technologist based in Copenhagen, originally from the UK, with a background in physics. I build software for a living, but I’m ultimately interested in systems: how things fit together, how they evolve over time, and how people work well with one another.

My work sits at the intersection of technology, relationships, and regeneration. Professionally, I lead software projects and provide consulting through Lake Lambda. More broadly, I care about building in ways that are sustainable — technically, socially, and personally — without losing curiosity, warmth, or clarity along the way.

What I Do

• Work on large-scale web delivery through Lake Lambda.
• Bridge enterprise Java systems and modern JavaScript front-ends.
• Design and ship modern web apps with React, Next.js, and TypeScript.
• Build data pipelines and backends with Java, Kafka, Spark, and Postgres.
• Integrate AI workflows with custom RAG pipelines and agents.
