Full-Stack Developer at MYPEGASUS Academy

Owned the architecture and delivery of a React, NestJS and PostgreSQL platform for the MYPEGASUS Academy, replacing spreadsheet tracking with a unified system of record for 100+ courses and ~400 participants. Unified conflicting, undocumented course administration workflows across offices into a configuration-driven system for ~40 internal users, reducing course setup time from weeks of paperwork to roughly two hours. Built analytics exposing frequently requested available courses, enabling prioritization of new internal training capacity. Implemented Keycloak role-based access (including read-only audit role) and an AWS pipeline for personalized certificate generation and delivery. Set up Docker-based GitLab CI/CD for staging and production deployments to a Kubernetes cluster on Hetzner. Modernized a legacy platform by migrating Java to TypeScript, upgrading dependencies, and consolidating two applications into an Nx monorepo with shared typed libraries and reusable company scaffoldin

Front-End Developer at iteign GmbH

Proposed and led adoption of a Lit web-components library to replace separate maintenance of React and Angular libraries, creating one cross-framework library and a shared design system used by four product teams. Documented the library in Storybook, making it the single source of truth for UI patterns and accelerating new feature development. Rebuilt the company marketing site from a legacy WordPress stack to Next.js, reducing page-load time by 25% via server-side rendering, improving Core Web Vitals, and increasing organic traffic by 30% after relaunch. Built an admin panel enabling non-technical teams to publish projects and landing-page content directly, removing developers from routine content updates.
