[ Quality & Performance Fanatic ]
Webmaster & Staff Software Engineer
Since 2016, I’ve had the privilege of being part of founding teams for corporate and venture-backed startups, owning critical aspects of product development and web infrastructure.
I enjoy optimizing processes beyond what was thought to be possible, in pursuit of maximum performance without compromising code and product quality.
Testimonials
If it's automated, monitored, or suspiciously reliable, Hans probably touched it. He turned our deploys from an adventure into a non-event, has a sharp eye for detail and zero ego, and is easily the best company on a late-night incident call.
Head of Tech Quality @ doinstruct
Backed by HV Capital with €16.5m, €26m total
I optimize and maintain the entire CI/CD pipeline as well as local and remote quality gates, build specialized tooling for automation, and routinely resolve critical/high prod issues of our Svelte + Sveltekit apps and our TypeScript backend, enabling devs across all teams to work more efficiently and with less headaches.
Scaled CI for agentic development: 4x increase in PR checks with 1.8x increase in GitHub Actions spend. Thanks to the monorepo migration, just 28% more devs produced 331% more output.
Rebuilt CI to be deterministic and extremely fast with custom changed files detection, highly optimized PR checks with <4min total check time, and local pre-commit and pre-push checks with custom lint rules.
Defined quality gates for the entire dev team so agent PRs meet the same standard as human-written code. Despite 7.7x PR count growth, red builds went down to 1/3rd of baseline.
Migrated all repos into one monorepo for maximum synergy: Same local + remote quality gates for all apps. Types, components, libraries, tooling, etc. shared via locally-linked packages; no build + publish step required.
Rewrote frontend session handling to be fully tab-agnostic, enabling employees to safely switch between clients for customer support, onboarding, or client demos without leaking other clients' data.
Founder @ hyperfocused agency
While on paternity leave, I ran my own web agency, providing design and web development services for small businesses and startups.
Founding Engineer @ Optimate
Corporate startup of TRUMPF
As founding engineer at Optimate, a corporate startup of TRUMPF (global market leader in industrial laser technology and machine tools) I was the main contributor to a now patented algorithm for automated 3D sheet metal part optimization and error analysis. This project involved using TypeScript + Vue.js, Python, and C to their limits to combine machine learning with complex state-of-the-art 3D transformations of STEP files.
I reduced the 20min duration of the CTO's POC down to 1.5min, creating an MVP that secured additional funding by TRUMPF to grow the startup, after which I became Tech Lead of a small dev team.
STACKIT started as a corporate startup inside Schwarz Group (Lidl & Kaufland), Europe's largest retailer. As the first and biggest European cloud, it stands to compete with AWS and GCP.
In a SCRUM team, I built the cloud portal frontend in TypeScript + Angular, and the MongoDB service broker in Go.
[ Deep reinforcement learning ]
In 2019, I built a state-of-the-art deep RL agent that learns server operations from admins. The admin rates its suggestions, and the agent updates its neural policy on the spot.
