Aitor Gallardo · @gmsudo · product engineer.
Full-stack & AI. I take products from idea to shipped — design, frontend, backend, native apps, and the AI in between.
Right now I'm building XSaved solo: a local-first bookmark manager for X. The Chrome extension is live with 400+ users and a 4.3-star rating, and the native iPhone app is about to launch — one sync layer behind both.
AI is moving faster than anything I've seen, and I'm having a great time keeping up — trying things the week they land, keeping what actually works. The rest is taste: small details, fast interfaces, things that feel right. If that's your thing too, say hi.
