Senior/Staff-level frontend engineer with 13 years at Ontraport, where I progressed from Junior Engineer to Senior Frontend Engineer and technical lead. I’m looking for a Senior or Staff Engineer role where I can stay close to the code while owning architecture, complex product work, and technical direction.

I’ve led products from early prototypes through production, including a graph-based visual automation builder, website/email builders, real-time multi-channel messaging, and data-heavy CRM interfaces. My work has included frontend architecture, complex state management, WebSockets and event-driven systems, performance optimization, reusable component systems, application security, TypeScript modernization, and occasional backend work in Go/PHP/Postgres.

I also spend a significant part of my time making engineering teams more effective: technical design and planning, mentoring, code/architecture reviews, debugging difficult production issues, and improving tooling and testing. I introduced Playwright and reusable mocked APIs for E2E testing, and more recently have incorporated Claude Code and other AI-assisted workflows into debugging, implementation, testing, legacy-code exploration, and review.

Best fit: a collaborative, product-focused team building complex web software where strong frontend architecture, UX, and engineering judgment matter. Especially interested in Senior/Staff IC roles at growing, mission-driven companies.
