What I'm looking for

I’m looking for remote product or software engineering work where I can take features from problem definition through implementation and deployment. I’m available for remote roles with European companies and for US remote contracts as a contractor.

At Freelance, I take product and frontend work from technical scoping through implementation and deployment. I’ve built and shipped Kumo, a personal finance product with AI receipt scanning, alongside Cicalino and Pickly.

At Mechanized (MechanizedAI), I built an end-to-end MLOps platform for managing datasets, training models, evaluation, and production rollout. I also built a tool to analyze, refactor, and translate mainframe and COBOL applications, and built VMShift to automate virtual machine workload discovery and migration assessment.

At Bellolandia Estudio, I identified friction in an animation production pipeline and built internal tools to streamline workflows; I also built and shipped the studio’s public website. Earlier, I worked in project management for audiovisual productions and contributed to frontend and data work at Selehann and Bosonit.
