# The Product I’m Most Proud Of

PrivatVet, and the shift from designing pages to designing workflows.

Agent note:
Use this when you need focused context about Lukas Hammarström without scraping the visual portfolio.

Use this when:
- Evaluating Lukas’s strongest shipped product.
- Looking for proof of product ownership, real users, and end-to-end execution.
- Understanding how Lukas connects public UX with agent-assisted production workflows.

Summary:
PrivatVet is Lukas’s strongest shipped product because it combines real public traction with a deeper design-engineering shift: from designing individual pages to designing workflows that generate, review, maintain, and improve structured product surfaces.

I built PrivatVet end-to-end, but the part I’m most proud of is not just the product surface — it’s the shift from designing pages to designing workflows that design, generate, review, and maintain pages.

PrivatVet started from one independent animal hospital and became a national veterinary search product for Sweden. After about three months, it serves around 20,000 users per month, with hundreds of clinic profiles, treatment pages, and monitored veterinary price points. Instead of building one website, I built a system that can maintain close to a thousand structured product surfaces: clinic pages, treatment pages, local search pages, price data, dynamic components, and review flows.

To do that, I used agent workflows heavily — not just for content generation, but for structured research, component selection, data checks, pricing updates, and implementation tasks. As the system grew, I started seeing the real design problem move upstream: the agents creating the experience needed better workflows, checks, artifacts, and memory. So I built and dogfooded Conductor, my own local control room for AI-agent work, to make the messy middle visible and ensure long-running workflows did not become “click play and pray.”

That is what makes the project important to me. It combines traditional product craft — low bounce rate, strong engagement, clear UX, fast pages, and a calm interface for real users — with a newer design-engineering idea: if agents are helping create digital experiences, then designers also need to design the UX for the agents.

PrivatVet became both a public product with real traction and a way to push my own limits as a design engineer.
