Expert Web Engineer · Angular & Frontend Architecture

Frontend change that sticks, because your teams own it.

I work as part of your team, not next to it, and bring the experience of having solved similar problems before. I fix what hurts, take good setups further, pair with developers, and give people leads honest feedback when something needs saying.

Part of your team, not next to it.

Fix what hurts, take good setups further

Slow builds, flaky pipelines and rendering bugs cost every team, every day. I go after the root cause, then leave the setup better than I found it.

Faster builds with Nx and Nx Cloud, visual tests only for what changed
Mobile CI/CD and iOS builds that work again
Lighter, faster in-house frameworks brought up to current practice

See the work

Pair, coach, and say what needs saying

Architecture only holds if the people building on it understand it. I review, pair and train across teams, and give people leads an honest picture.

One Angular architecture, held across every frontend team
Reviews, pairing and training sessions for developers
Teams introduced to working effectively with AI
