I build and ship Flutter apps, Ruby APIs, and robotics software.
PolandWhat I'm looking for
I owned iOS and Android releases at Florence for a healthcare shift-work platform with 250,000+ active users, building Flutter features and Ruby REST APIs while using Sentry, Mixpanel, Customer.io, CodeMagic, and Bitrise to improve releases and prioritise fixes.
As founder and sole developer at JJKSoftware, I scoped, designed, built, and shipped Drooli end to end: a commercial canine nutrition app with FEDIAF-validated meal plans, nutritional gap analysis, recipe libraries, shopping lists, Shopify integration, and ongoing support.
My robotics engineering background includes cross-platform training software, manufacturing control systems, and a 5-axis robotic 3D-printing system. I also build hardware and venture products spanning AGVs, CNC machines, electronics, and companion mobile apps.
