Frontend Team LeadTechnical Lead

I believe in a fully accessible internet, and I build towards it.

About

I lead a team of front-end engineers at Unic, a Swiss digital agency, and work as Frontend Lead and Technical Lead on projects for enterprise clients such as Richemont, ETH Zurich and FINMA. My work sits between people and code: hiring and growing engineers on one side, front-end architecture and delivery on the other.

Accessibility runs through all of it. I build to WCAG 2.2 AA from the design system up and help teams meet the European Accessibility Act. I also bring AI-assisted workflows into everyday engineering, so teams can ship faster without lowering the bar.

Experience

  1. Frontend Team Lead Unic

    Present Team Lead since 2022

    I lead a front-end team that grew from 8 to 16 engineers, from hiring and onboarding to development plans and promotions. On enterprise projects I act as Frontend or Technical Lead, owning front-end architecture from design systems to headless CMS integrations and CI/CD, with accessibility to WCAG 2.2 AA built in.

    I build websites for small and mid-sized businesses end to end, from development, hosting and integrations to content and ongoing support, always with a focus on accessibility. I also carry out accessibility audits against WCAG 2.2 and the European Accessibility Act, with clear recommendations for fixes or their full implementation.

Education

PhD in Management

Wroclaw University of Economics and Business ·

Dissertation, awarded with distinction: “IT Project Management in Companies with a Holacratic Structure”. My research looked at how agile IT companies move to holacracy, a role-based model that replaces hierarchy with decentralized decision-making. Drawing on companies going through this change, I designed a model implementation process, from preparation and milestones to the links between agile project management and holacracy, along with criteria that show when a company should not attempt the transition.
