Started full-stack, evolved into frontend architecture. Shipped production systems across payments (PCI-DSS), healthcare, banking, e-commerce, and ed-tech — Angular, React/Next.js, and Stencil micro-frontends powering €1B+ in revenue. Ranges across web, mobile (Ionic), and desktop (Electron). Recently built a 12-agent AI engineering platform in production. Currently embedded at Betsson (Malta, EU). Senior/Staff/Principal track.

$ cat ~/.unknowns # things i'm actively learning - knowing when AI-assisted engineering is a force multiplier vs a debt accelerator (built the 12-agent system at betsson. also watched what it produces when nobody reads the diffs.) - writing specs that someone else can ship without me in the room (the 35-page knowledge system was a start. specs are harder. "what i meant" is not what i wrote.) - deciding what NOT to ship (the feature that doesn't ship is the one that doesn't cause an incident. learning to advocate for cuts.) - opening a 1:1 with something other than "so, how's your week?" (the icebreaker question IS the conversation. learning to ask better ones.) - learning to be wrong in public without making it the story (engineers who admit mistakes loudly are usually still making it about them. fix it, move on, stop performing the apology.) # things i've chosen not to specialize in (yet) - mobile native (ios/android beyond ionic) (shipped ionic for 5 OSes once. that was enough.) - ML model training / research (applied-AI consumer, not researcher. the agents are the layer i own.) - chasing the framework wars (i've shipped the same architecture pattern in 4 different syntaxes. the syntax was never the hard part.) > open to roles that push me harder on any of the above.
