Hi, I’m
Pablo Cigoy
Software developer — full stack, mobile & UX/UI, building further with AI.
I build apps from zero, knowing how every layer works — and use AI to go further, faster.

Manifesto
In 2022 I learned to code — full stack, mobile and UX/UI design. I built apps from zero, understanding how each technology works. (Yes, including how to center a div.) On top of that foundation I now build complex products with AI — a tool that makes us more productive and takes us further. Everything can be programmed.

AI inbox assistant · padel club
Internal tool my team at the club uses every day to answer customer email. It syncs the shared Gmail inbox, translates each message into German, English or Spanish and drafts three replies grounded in a staff-editable knowledge base. Staff edit in any language and the reply goes out in the customer’s. Weekly PDF reports are generated automatically.

Live tournament scoring · 4PADEL Berlin
A tournament app I built for team events at the club: one tablet at reception enters results while players and the club TV follow live standings. Offline-first with no backend — a pure TypeScript ranking engine with tie-breakers, local-first state and cross-screen sync, covered by 27 unit tests.

Gym logger with AI coach

AI personal stylist · wardrobe PWA
An app I built to organise my wardrobe: photograph each garment once and get outfits for any occasion, trip plans with live weather, and a buy-or-skip verdict while shopping. The styling runs on a fashion-expert skill I wrote, and outputs only reference garments I actually own.

Background
About me
I’m Pablo Cigoy, a certified mobile app developer creating apps and digital solutions — mobile and web — that are user-friendly and efficient.
I love technology and building solutions to real problems. I’m curious by nature: I keep learning about AI and putting new tools to work — many of the tools my team uses every day at the padel club are apps I built myself. Before code, I spent over ten years leading kitchen teams, which taught me to stay calm under pressure, organise people and deliver. Outside of work: cooking, traveling and cycling.
