Fullstack Engineer Wunderflats GmbH
Led discovery and technical design for Editable Contracts, including analysis of more than 9,700 bookings, a full-stack proof of concept, and detailed API and frontend implementation specifications. Identified contract-change workflows as a significant operational issue, with 29% of bookings entering cancel-and-recreate cycles and operations-mediated cases taking 2.7 times longer to close.
Drove B2B company-paid booking functionality across APIs, website, and Backoffice systems. Implemented backend and internal-tooling functionality, authored website specifications, and designed tokenized company portal pages for external self-disclosure and contract signing.
Rebuilt search-result filtering end to end across frontend and backend for pricing, dates, beds, amenities, apartment size, and occupancy. Extended YouSign e-signature workflows from German and English markets to France, including templates, selection rules, override tooling, and production support.
Built and maintained Backoffice and CRM features for listing, booking request, contract, and contract-creation workflows. Improved engineering planning through a custom Claude Code workflow for Jira epics and tickets, and resolved flaky Cypress end-to-end and API tests to improve CI feedback reliability.
