About
A small studio that ships.
Fanxie Lab is a digital studio in Bogota, Colombia. We build WordPress sites, web applications, and iOS products for companies that care about how their software actually works — not just how it looks in a pitch deck.
We've been at this since 2016. No venture funding, no 200-person team, no account managers. Just a tight crew that writes clean code, hits deadlines, and picks up the phone when something breaks.
Founders
Built by developers, not salespeople.
Fanxie Lab was founded in 2016 by David Paternina (CTO) and Jairo Mendieta (CEO). Two people who kept seeing the same problem: agencies that talk a big game, then hand the real work to junior devs and hope nobody notices.
David Paternina — CTO
10+ years building for the web. Since co-founding Fanxie Lab, David has spent time at MonsterInsights — the WordPress analytics plugin running on 3 million+ websites. That experience shaped how he builds: production code at scale, performance budgets that actually get enforced, and the discipline of shipping software that millions of people rely on.
The stack runs deep. WordPress internals, Laravel backends, Vue.js frontends, native iOS in Swift and SwiftUI. Not "familiar with" — built production systems in each. When you work with Fanxie Lab, the person scoping your project is the same person reviewing the pull requests.
Jairo Mendieta — CEO
Jairo is the one of us who actually holds a degree. He's also spent time at Siigo — one of Colombia's largest accounting software companies — leading a team building scalable features as microservices.
He handles client relationships, project scoping, and the business side of the studio. But he's technical to the core — he can read the code, challenge architecture decisions, and keep engineering honest. Clients get straight answers, not filtered ones.
How We Work
Right tool. Right reason.
We don't have a "house stack" that gets shoehorned into every project. WordPress makes sense for content-heavy sites that need to scale. Laravel and Vue.js are the right call for custom applications with complex business logic. SwiftUI is the answer when native iOS performance and App Store distribution matter.
Performance is not an afterthought. It's the first constraint. Sub-2-second load times. 99.9% uptime. Lighthouse scores that would make your last agency uncomfortable. We set performance budgets at the start of a project, not after the client complains.
We write tests. We document our code. We set up CI/CD pipelines so deployments are boring and predictable — exactly how deployments should be.
The Studio
Small on purpose.
Fanxie Lab was founded in 2016 with a straightforward thesis: a small team of strong developers will outperform a large team of average ones. Every time. We stay lean because it keeps us honest. No layers between the client and the people doing the work.
We're based in Bogota, which means real timezone overlap with North America — same business hours as EST and only 1-2 hours off from the rest of the US and Canada. No 12-hour feedback loops. No waiting until tomorrow for an answer to a question you asked at 9 AM.
We also build our own products. Kiveo (an iOS reading journal with 500+ downloads), BeaconStat (usage analytics for distributed software), and SunShift (coming soon). That's not a side hustle — it's how we stay sharp. When you build your own products, you learn things about reliability and maintenance that client work alone never teaches you.
