Digital accessibility expertise for consulting firms
Partner with an experienced accessibility specialist to deliver WCAG-compliant auditing services for your clients. Over 20 years of development expertise combined with specialized accessibility knowledge.
About
Hello, I'm Heidi Valles, a developer and digital accessibility specialist with 20+ years of experience building for the web. My background includes a decade at the Inclusive Design Research Centre (IDRC) developing open-source accessible web applications, plus years of freelance work for design firms building production-ready sites from mockups.
Today I provide accessibility auditing services to consulting firms and offer selective development work on projects that center inclusion. My technical background informs how I approach accessibility evaluation - I understand what's technically feasible, what's unnecessarily complex, and how to write recommendations that development teams can actually implement.
I've worked across government agencies, higher education institutions, non-profits, and enterprise clients, bringing practical accessibility expertise to organizations navigating WCAG compliance and accessibility legislation.

Frank Maidens - Studio Function
I needed a developer who could execute a full-scale web app accurately, on-time, and without surprises. I've worked with a lot of developers over the years, and let me tell you - it is tough to find responsible devs who have the technical chops and an intuitive understanding of design. Working with Heidi was a pleasure and I'd hire her again!
