Case Studies
I am a Senior Frontend & Full-Stack Engineer with 11+ years of experience building web applications in React, Next.js, TypeScript and Node.js. For the past 4 years I have led the frontend at Doccle, a document platform used by 2.5M people.
Design system
building 100+ components in Storybook on React Aria and moving every Doccle app onto them
AI workflow
turning AI coding into real team productivity
Payment widget
one Next.js widget for every app and the start of migration
Frontend Harness
turning my frontend standards into checks the AI must pass
What I bring to a team
- Frontend leadership: I joined Doccle as the only frontend engineer and led the move of the whole product from Grails and Angular to Next.js while shipping core features with backend engineers from several teams. At DasLab, as Technical Frontend Lead, I grew the team to 5 engineers and set up code review, testing and releases.
- Architecture: At Doccle I own the frontend architecture of the Nx monorepo and built its design system of 100+ accessible components, moved every app onto it and raised test coverage to 70–80%. At Webjet I led the migration from AngularJS to Vue. At Blackbell I migrated old functionality from Backbone to Vue.
- Features end to end: I shape scope with product owners and propose simpler solutions. At Doccle I built a complex payment widget that began the migration: prototype in 2 mo, MVP in 6 mo. It now runs in many apps and pages. At DasLab I chose the stack for 2 apps from scratch (patient booking, lab admin), behind 600K+ test results.
- AI workflow: At Doccle my AI guidelines keep code consistent team-wide, backend included, and an agent takes a task from Jira to a merge request, which speeds up delivery and eases code review.
What I'm looking for
A senior full-stack, senior frontend or frontend lead role in a product company or startup. I'm based in Wrocław, Poland (CET) and work remotely.
