Product Engineer

Tech Lead2023 — present

Technical lead for two product teams (9 people) on a case-management application used by 40,000 civil servants.

• Monthly discovery with product and design: interviews with civil servants, prototypes built in a few days with AI tools and tested before the first line of production code.
• Feature flags and progressive rollout: every new feature reaches 5% of users before going wide.
• In-house design system: 42 documented components, adoption tracked on a usage dashboard.
• Accessibility: full audit, 180 issues fixed, keyboard tests wired into CI.
• Observability: distributed tracing, per-service error budget, shared on-call and written post-mortems.
• Monthly architecture review with the other leads, decisions recorded as ADRs.
