Six companies, four very different domains. I started in e-commerce — online retail for home and construction, a huge catalogue and traffic that spikes hard on a single shopping holiday. From there I moved to payments infrastructure: card issuing and banking as a service, the kind of system other products are built on top of. Two opposite schools — one teaches you what volume does to code written in a hurry, the other teaches you that a mistake costs someone real money.
Then came travel, on a platform selling airfare at scale, and last-mile logistics, wiring physical stores into marketplaces for fast delivery. Real operations: when the system goes down, somebody feels it immediately. After that, open-source core banking — the first time code I wrote was read by people outside the company, which changes the standard of care.
Today I work in corporate governance diagnostics, on a platform that assesses how mature a company is and turns the result into a plan of action. And I'm the founder of Singularity — a product studio focused on turning product into revenue. It's the sum of all of it: after six companies, it became clear to me that the bottleneck is almost never technical.
