Yannic Oberhausen

Senior fullstack developer at LEWO Media in Trier — SvelteKit, NestJS and Shopware, end to end.

01 — About

Systems that hold up under real load.

Fullstack developer at LEWO Media and computer-science student at Hochschule Trier. I care about interfaces that feel deliberate, services that stay boring under pressure, and the integrations that keep both honest.

    PRIME TIME fitness

    PRIME TIME fitness · Senior Full Stack Developer

    Digital sales platform for a premium fitness chain across Germany and Switzerland: locations, plans, campaigns and online membership signup in one system. I built the signup funnel with its HubSpot and Yond integrations, and took part in bug-fixing — mediating issues between client and team, and fixing them myself.

    Van Volxem Online Shop

    Van Volxem · Lead Developer

    Online shop for a leading Saar winery. I built most of the front end from the team's designs, along with its integration with the Shopware backend and the shop logic. I also wrote two Shopware plugins — a Typesense search integration and an ERP integration — added PostHog analytics, and handled maintenance and bug-fixing.

    Luxfit

    Luxfit · Senior Full Stack Developer

    Website for a personal-training studio in Trier and Luxembourg, built around the idea of a personal health coach: individual, trustworthy, results-driven. Full-stack work across the whole site — the SvelteKit and Tailwind front end, the NestJS backend behind it, and delivery through Cloudflare — plus bug-fixing and maintenance after launch.

    TUFA Trier

    TUFA Trier · Senior Front-end Developer

    3D website for TUFA Trier, the city's cultural and communication centre — events, exhibitions and workshops presented so that the energy of the place carries onto the screen. A larger front-end role: I built many of the components and pages of the SvelteKit front end, implemented the CMS integration behind the content, and took on maintenance and bug-fixing after launch.

    Etges & Dächert

    Etges & Dächert · Senior Front-end Developer

    3D website for Etges & Dächert, a family-run building-materials supplier. The brief: make a trade that reads as dry and technical feel approachable and modern without losing its down-to-earth character — so the site is built around an interactive 3D house that shows how, where and with what they support a build. Part of the front-end team; I built several of the subpages of the SvelteKit front end.

    SafeMind

    SafeMind · Senior Full Stack Developer

    Software for the psychological risk assessment every German employer owes under § 5 ArbSchG: anonymous employee surveys, automated evaluation and audit-ready PDF documentation along the seven-step GDA process, from a three-person shop to 5,000 staff. Full-stack work across the product — the SvelteKit site with its guides and compliance checker, the customer application behind the login, and delivery through Cloudflare.
