Most of this work was delivered on behalf of an agency rather than as a direct mandate. The filter above says which house each name ran through — WONDROUS, Winterthur Medien AG, or neither.
Instead of testimonials you would have to take on trust: things you can check yourself.

30+ projects I built with AI assistance — from hardware drivers and trading bots to bug-bounty workspaces. Four of them are open source and publicly inspectable.
Polobase/exquis-midi
Full-control TypeScript library for the Intuitive Instruments Exquis MPE controller (LEDs, input, microtonal layouts) over its Developer Mode MIDI API.
Polobase/freqgen
TypeScript drivers for USB-serial signal/frequency generators (FeelTech FY, JUNTEK, Koolertron, Spooky2) behind one vendor-neutral SignalGenerator interface — same API in Node.js and the browser. Grown out of feeltech.
Polobase/mindpeeker-sdk
Zero-dependency TypeScript/Bun SDK for consciousness research: randomness engineering to NIST SP 800-90B with extractors and VDFs, plus a browser playground. The SDK alone is open source.
Polobase/muse.js
TypeScript library for Muse EEG headbands, with first-class Muse S Athena support. Decodes the DRL/REF pair no other library reads.

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.
