[ 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.
