I manage managers, not just engineers — around 30 people across three full-stack squads in Delivery Hero's Vendor Discovery domain. Part of that is a revenue-critical squad I run direct, no EM layer between me and its ICs, which mostly means I don't get to hide behind a delegation buffer when something breaks.
15+ years in engineering, most of it hands-on before I moved into management, which is why I still sit in architecture reviews and push back on RFCs instead of just rubber-stamping them. GraphQL Federation, mobile SDKs, event-driven systems — that's the stack I came up on, and it's still what I reach for when I need to tell a good technical decision from a convenient one.
A few outcomes I'd stand behind in an interview:
- Scaled the domain 20 → 30 engineers, cut onboarding ramp time 40% by restructuring around C4 reviews and ADR/RFC governance
- 100% retention while growing 7 engineers into EM/Staff roles
- Cut MTTR 4h → 1h and incidents 42% YoY across 300+ services, with on-call and multi-AZ DR I own directly
- Led Delivery Hero's first org-wide GraphQL Federation rollout, co-authored the supergraph architecture, presented at GraphQL NYC Summit
- Rebuilt vendor discovery ranking/personalization across 19 markets — €52M incremental annual revenue, 32.1% revenue growth

Unarchive.today — a privacy-first, offline-first read-it-later app for archive.today and archive.ph links. Share an archived link from anywhere and it opens natively instead of making you copy-paste into a browser tab, and it can summarize the page with an on-device local LLM (Gemma-2B / Llama-3.2 via MediaPipe and CoreML) — nothing leaves the device, no accounts, no server-side reading history. Built and shipped solo to iOS and Android.

Initiatives I've directed at Delivery Hero — not solo builds, but ones I sponsored and shaped:
| What it does | Impact |
|---|---|
| Agentic architecture-drift auditor checking every deploy against reliability standards | Review no longer bottlenecks on senior ICs across 300+ services |
| LLM agent that watches UI flows and writes regression tests automatically | Test authoring: 1.5 days → 5 minutes |
| One-click mobile regression platform | Manual regression: 132 hrs/week → under 20 |
| Grew out of a bottom-up R&D program I run for the team | 60% faster A/B cycles, ~€500K capacity unlocked |
