Curriculum vitae / Vienna, Austria
Lukas Wittich, BSc
Lead Developer · Full-Stack Developer
Profile
I’m a product engineer with a founder’s mindset and more than ten years of full-stack experience. Agents write most of my code now, so I focus on both ends: understanding why something should be built, and building the guardrails and review that make agent output safe to ship.
I try new tools early and keep the ones that earn their place. Family comes first, so work-life balance matters to me.
How I work with AI
I build through agents, and I build the system around them: briefs with clear acceptance criteria, context and rules that load when they’re needed, fixed checks for what must never break, and review that follows risk. When a tool is missing, I build it myself.
- Agentic engineering: Agent workflows, guardrails, review and delivery systems
- Product & domain: Requirements, product engineering, a founder’s view of the business
- Apps: Web and mobile, frontend to backend
- Systems: Distributed systems, messaging, APIs, integrations, payments, crypto
- Infrastructure: Servers, containers, cloud, scaling, hardening, zero-downtime operations
