Team building & hiring — 20+ engineers hired at Just Eat Takeaway across the tenure; built and led teams of up to 12 direct reports. Mentoring — deliberate and ongoing across every role: senior and medior engineers on the platform team and in downstream consuming teams, through code reviews, design discussions, and pairing on hard problems. Clean handovers — trained app teams to own what I built (PostgreSQL tuning runbooks at Brenntag, interns running the Seenons platform independently). Cross-discipline communication — comfortable from kernel-level engineering through to non-technical stakeholders; reshaped Booking's internal tech-talks format (still in use after my tenure). Calm under pressure — established 24/7 on-call culture at JET; production debugging at petabyte scale at Booking.

I'm not your ordinary data engineer. Twenty years across travel, food delivery, circular economy, industrial distribution, through mergers, expansion, green fields and legacy struggles, I think I've done as much as you can imagine and always delivered. What I bring is range. Wide and deep. Need a misbehaving DNS resolver fixed, disk buffers retuned on a hot Postgres box, a CSS rule that finally lays out right, or a data-quality bug nobody else can reproduce? I can, and I will, and it'll work. It always does. Imagination, small sharp tools, going a layer deeper than the brief asks for. The systems I build hold up under load. The teams I build outlast me. The handovers are clean. I work best where the scope is open and the problems are real.
