Product strategy,
shipped and scaled.
I’m JC, an engineering lead building Huppa, the operating system for class-based sports, and going deep on agentic engineering.
Built from the ground up.
Based in the Netherlands, I built the product behind Vesper, one of the fastest-growing Dutch startups, from the first line of code. I’ve also led SaaS, e-commerce and high-traffic platforms from their first technical decisions through delivery and scale.
What six people I’ve worked with say about me.
-
“I had the pleasure to work together with Jecan to build a new platform from scratch. His skills about setting up the architecture of the application was also something we all could rely on.”
Alessio EvangelistaTech Lead -
“Jecan worked in our backend engineering team and I can vouch that he writes clean, modern Laravel code. If you are building a Laravel product, Jecan can be a great asset for your company!”
Denis MysenkoCTO -
“When Jecan was working on a project, our error-correction needs were always reduced by half or more thanks to his outstanding diligence and attention to detail.”
Oleksander DyriavinLead Software Engineer -
“He is in the top tier of developers I’ve worked with. It was a pleasure working with him and I sincerely hope to work with Jecan again.”
Eduardo StuartSenior Software Engineer -
“Besides delivering what he is tasked with, Jecan always goes a step further, making sure the users get the best experience.”
Marjon SieroProduct Designer -
“He is someone that would open for challenges and solve problems as a team-player.”

Move fast, without the mess.
I give teams the structure to ship quickly while the codebase stays easy to change. Agentic engineering runs through every layer: agents carry the throughput, while playbooks, reviews and proof keep the quality high.
I shape the roadmap with product and engineering, and make the early technical decisions.
Domain-Driven Design, event-driven architecture and pragmatic design, with legacy isolated so it stays sustainable.
Hands-on with backend systems, APIs, distributed systems and complex integrations.
Every task starts from a playbook. Coding agents do the building, a second agent reviews each change with fresh eyes, the result is proven on the real product, and a human owns the design and the final sign-off.
