Product Owner building software for solar, heat-pump and EV installers at 2Solar by Sollit. On the side: a small Dutch web studio, a loud homelab, and a deep suspicion of any process that claims to be special.

01 — what

What I actually do.

Four lanes. Day job first, the rest second.

product

I build software for the solar industry — specifically 2Solar by Sollit, a platform that tries to get installers of solar panels, heat pumps, EV chargers and home batteries from first customer contact to invoice without setting fire to their own planning. Product Owner since April 2024.

I arrived at product the boring way: enough time in support, control, and implementation that eventually someone let me near the roadmap. A lot of the job is translating "our process is unique" into "it's the same bottleneck with different labels", and turning urgency into prioritisation — corporate Dutch for disappointing people with structure.

build

Outside the day job I write code. Mostly TypeScript — Next.js, Node, a boring relational database, sessions I can actually reason about. I like small tools that do one thing well and outlive the framework churn, and I'd rather ship something modest on Tuesday than something heroic next quarter.

self-host

I run a small rack at home: Proxmox hypervisor, Unraid NAS, 32 containers, 346 TiB of storage, automated TLS, backups to Cloudflare R2, my own mail, my own media. Overkill for the studio, completely unnecessary for the day job, and useful for staying honest about how software actually behaves when nobody is watching.

studio

At younique.dev I take on a handful of client projects a year — websites, web apps, and small internal tools for Dutch SMEs. One person, direct contact, no templates.

02 — path

How I got here.

Sales support → service control → business control → implementation → product. The long way around, on purpose.

2024 → now
Product Owner — 2Solar by Sollit
before that
Customer Success Implementation Specialist — 2Solar by Sollit
earlier
Business Control · ICT & Service Control · Sales Support — Volta Solar BV
first gig
Technical Support Specialist — Kabeldirect B.V.

By the time I started writing roadmap items, I'd already lived in the planning board, the service tickets, and the billing runs. I trust customer input more when it survives contact with actual implementation.

03 — stack

Tools I actually use.

Boring, bewezen, debugbaar om 23:00.

04 — work

Selected work.

The things I put my name on.

  • 2Solar by Sollit — installer platform for solar, heat pumps, EV chargers, batteries. Day job, Product Owner.
  • younique.dev — small Dutch web studio, client sites + internal tools. Owner and builder.
  • homelab — Proxmox + Unraid, 11 LXC, 32 containers, self-hosted mail, media, backups. Private, happy to nerd out about it.
05 — now

What I'm working on.

A honest snapshot of this week, not a roadmap.

  • Quote + planning flows at 2Solar — the bit where installer reality meets accounting reality.
  • Moving a handful of Dutch client sites off shared hosting onto infra I can actually debug.
  • Making the homelab backup + restore drills boring on purpose.
  • Trying to stop writing landing pages that look like every other Claude Code output.
