Leadership & mentorship
More than a Senior Dev
I set architecture direction, raise delivery standards through design and code reviews, and build talent pipelines — from enterprise squads to MentorBridge graduates entering full-time roles.

Direction that scales
Governance, technical roadmaps, and reusable frontend foundations so squads ship on shared patterns instead of reinventing the platform.
