Looks like you have JavaScript disabled. For the full Twine experience, you will need to re-enable it.

I'm a seasoned frontend-leaning full stack JavaScript engineer with over 16 years of experience across the full delivery lifecycle — from scoping, pricing, resourcing, architecture and API design to frontend implementation through React or VueJS. Equally comfortable working deep in the stack as leading the team, I bring a strong engineering philosophy centred on quality, maintainability and knowledge-sharing. I have a proven track record of joining fast-moving teams, identifying what needs to improve, and making it happen — without sacrificing pace. In lead roles I have steered projects and recruitment toward quality, delivering tens of high-traffic, industry-leading sites under challenging deadlines. In contract roles I deliver well-documented code that hits test coverage, accessibility and SEO standards. Mentoring less experienced engineers and helping them grow into confident, independent contributors has been one of the most rewarding aspects of my career. I’m also up to date with agency workflows, creating plugins and automations to scaffold components via design tokens and design-system workflows using Figma MCP servers.…I'm a seasoned frontend-leaning full stack JavaScript engineer with over 16 years of experience across the full delivery lifecycle — from scoping, pricing, resourcing, architecture and API design to frontend implementation through React or VueJS.
