My name is Gonzalo Bilune, though almost everyone calls me Bilu. I work from Argentina, and I'm Head of Engineering at Aerolab, a product agency. My job is the engineering organization: how teams are put together, how they work, what their leaders need to keep them going, and how we bring AI into everyday work without it ending up as a nice demo.
I come from the other side, from product companies. At Mercado Libre, Ualá and Pomelo I learned fintech up close: payments, card issuing, digital banking, and the healthy paranoia that shows up when the thing you break is somebody else’s money. I brought that discipline with me. Aerolab is a different kind of hard. Many businesses at once, clients who expect something concrete, and teams that have to understand an unfamiliar business fast and ship well anyway.
Over the years my work kept moving. First it was writing code, then leading a team. At Pomelo I led leaders: a vertical of about 16 people, two teams through their TLs and staffs, covering tokenization, fraud, compliance, settlements, cards, shipping, 3DS and identity. The question changed there. It was no longer how I solve this, but how I build a place where people solve it without me. AI works the same way: trying tools is easy, and getting a whole organization to change how it works is the hard part.
I come from frontend and design engineering, and it shows. I still care that what we ship is well built and that people can use it without fighting the screen. Now I also care that an AI agent can use it, which is what I talked about at SEOday in Mexico City, on behalf of Aerolab.
SEOday 2026, Mexico City (Masterclass Room, Hyatt Regency Polanco) · October 14, 2026
I gave a masterclass on agent experience (AX) on behalf of Aerolab, invited by Punto Rojo. I talked about what moves an AI agent forward or stops it before it completes a booking or a purchase on someone’s behalf, and how to measure whether your product is ready.
Talks by Pomelo 2023, with Andy Cuello
Andy and I told how we moved Pomelo’s dashboard from a monorepo to microfrontends integrated at runtime, and why coordinating people was the hardest part.
I publish notes here about engineering leadership, how teams are organized, what changes when you lead leaders, metrics, and how organizations adopt AI. Some fintech and frontend too, since that is where I come from. I write in Spanish and translate whatever might be useful to more people. Most of it comes from something that happened at work that I only understood much later, usually after getting it wrong first.
