I keep large codebases easy to work in.
For the last two years I’ve owned the frontend’s technical direction at Agenta and led its frontend team. Agenta is an open-source platform for building and evaluating LLM applications, and since mid-2026 an agent builder. Before that I led the engineering team at Medbelle through a framework migration, a monorepo consolidation and a design-system replacement, none of which were allowed to stop delivery. I’ve been writing React since 2015.
I’ve spent my career in startups, twice as a founder, and I started out on the product side, testing MVPs at a venture builder before I wrote production code. The habit that survived the switch is asking what a feature is for before building it; unbuilt features are the easiest ones to maintain. When something matters I take it end to end.
Never write the second copy.
If two surfaces need the same thing, I extract it into a shared package, stylesheet and tokens included. A component extracted without its styles renders wrong, and nobody catches it in review. I don’t trust my eyes on that kind of change, so I diff the generated CSS instead.
I build LLM tooling for a living, and I build with it daily. What made agents useful on my team was giving them a defined surface to work against: a skill written per extracted package, and test suites shaped to what each package needs.
iOS · ARKit + Core ML · personal project
A point & shoot HomeKit remote. Map a room once and the next time you walk in, the controls are already floating on the devices. The glow is v2: a segmentation model running on the phone, tracing whatever you tap.
Lead Product Engineer · open-source LLM engineering platform, now an agent builder · Berlin
I owned the frontend’s technical direction and led the frontend team: the architecture, the library choices, the shared package layer.
Engineering Team Lead · digital healthcare · Berlin
I stepped into the lead role when the CTO moved into product, and ran the engineering team owning three patient-facing applications and the marketing site.
Startup Lab, part-time · hands-on entrepreneurship · Berlin
I instructed and mentored every semester from graduating until I joined Medbelle: business-model and hypothesis validation, build-measure-learn loops.
Berlin · Seelze · Istanbul
I co-founded DotLab, an e-commerce studio in Berlin, and ran it for three and a half years. At Wintech PS I ran InnHof, an intrapreneurship project inside an international manufacturing firm, and steered its pivot from a physical innovation centre to a digital one when the parent company halted the building programme. I also co-founded Overthink, an MVP studio in Berlin, whose own product was Synnc, a social music-listening platform I led the iOS app for. Earlier I product-managed at the Startup Kitchen venture builder in Istanbul.
