About Me

Brian van Vlymen

I am a Senior Full-Stack Engineer · AWS Cloud Engineer with a Computer Science background from UTSA and a deep commitment to digital inclusion.

I build and ship production systems end-to-end. I am currently the sole architect of besHandyman, a two-sided home services marketplace with Stripe Connect payments, MongoDB Atlas, and AWS ECS — and previously lead developer at InterPicker, a subscription SaaS platform on AWS with Next.js, MongoDB Atlas, Docker, and Nginx. Alongside client work I build a11y-auditor, a serverless WCAG auditing service on AWS Lambda, SQS, and DynamoDB, provisioned entirely with Terraform.

As a certified Web Accessibility Specialist (WAS), I believe the most powerful systems are the ones that everyone can use, regardless of ability or device. I build with AI tools daily — and my certification is what lets me verify their output actually meets WCAG. In an era when anyone can generate plausible code, verified judgment is the differentiator. My goal is software that is as secure and scalable as it is accessible.

Flagship build: a serverless accessibility auditing service on AWS. Playwright and axe-core scans run on a queued Lambda worker, results land in DynamoDB and S3, and the Claude API explains each violation in plain English — all Terraform-managed for under $2/month.
