Fast-charging stations for electric vehicles across Europe. I manage two engineering teams.

• Charging: the OCPP layer, 99.9% uptime across 2.9k+ chargers.
• Roaming: logic and charge cards that process 80-90% of Fastned’s EUR 122.4M 2025 revenue. We don’t generate it, we make sure it clears.
• Restructured the original Protocols group into these two autonomous teams.
• Led architecture and delivery for Fastned’s biggest transformation: charge point operator to mobility service provider.
• Founded and lead the AI Squad, plus a suite of internal apps: workshops, dashboards, and cost-optimized usage that cut delivery effort by an order of magnitude.

Most of the job is keeping revenue-critical infrastructure boring, which takes more work than it sounds.

Agentic analytics: ask a business question in plain English, get a live dashboard back.

• Co-founded and ran it as CEO: product, architecture, data modeling, plus sales, demos, contract negotiation.
• Close to 100 discovery calls, 50 demos, 6 pilots on their own data, first paying customers; peak revenue about EUR 900 a month.
• A distribution partnership turned into a consultancy relationship across their 300 clients.
• Dec 2025: two founders with day jobs, one also finishing a master’s; my cofounder made the sustainable call to keep his better-odds bets, and the product path ended there.
• Became a data and AI consultancy for a while: MCP layers and pipelines for legacy SaaS. Wound down in 2026.
• Sep 2026: the big AI labs shipped the core of what we built into their own products. Right and early.

My most impressive product and my least impressive commercial outcome. The gap between the two is the education I carry into the next one.

Virtual try-on for fashion e-commerce.

• Rebuilt the product and technical org from scratch: architecture, infrastructure, execution, client relationships.
• Empty repo to a production system with paying customers in under three months.
• USD 300K ARR by month three, with me in every deal: clients signed after long sessions with their technology teams on technology, safety and data, and I ran those.
• Stepped back in Nov 2024 for geography reasons, moved to Fastned.
• Still running today, without me. That’s the outcome I’d pick again.

Founding engineer at a fintech startup, four and a half years, one of the first hires.

• Wrote across the stack: C# and Java tools for internal and customer use, Scala and Python for data work and debugging, Bash-driven automation for the build pipeline.
• Up to 200% throughput and 80% faster deployments from the infrastructure work.
• Led the company’s largest client integration end to end: requirements, product changes, fast issue resolution.
• Recruited and onboarded engineers as the team scaled.

Five years watching a startup grow from a handful of people into a real company. A different kind of education than the one before it.

General speech engines choke on specialty vocabulary. This one didn’t.

• Built for an NHS client to transcribe medical dictation across Haematology, Urology, Radiology, and Oncology, each with its own terminology.
• Trained the model on YouTube lecture and conference audio with matching transcripts instead of hand-labeling data from scratch.
• Team project at UCL.

The client-specific vocabulary problem in speech recognition never went away. It just moved to LLMs.

Most of my code these days is written by coding agents.

• The hard part isn’t prompting, it’s operations. Agents are stateless, so everything durable has to live in files.
• Fixed root files, one job each, read in the same order every session.
• Hard line caps so state always fits a fresh context window.
• Repeated tasks become executable skills instead of being re-improvised.
• Every handoff gets written down; the next agent reads it first.
• Verified like code: spawn a fresh agent, quiz it against ground truth, fix the files, not the agent, when it fails.
• Sep 2026: cut the gates, quotas, weekly reviews and most rituals. What survived: the file protocol, the session log, one improvement per session, and an agent configured to challenge me.
