About me

Manuel Haller Polo

Building for the web since 2013, focused on blockchain since 2022. I work as a senior generalist with three sharp specialisms: modern frontend, AI and automation, blockchain and Web3 — a combination that rarely comes together in one person.

Four of those years were spent as a frontend developer at a Swiss digital agency, delivering applications for pharma, industry and finance clients. I have worked independently from Basel since mid-2024, as a registered sole proprietorship since January 2026. 40+ documented client and reference projects, 14 certificates — nine of them in blockchain and DeFi.
