ScanAble — Automated Accessibility Compliance Scanner
I built and launched a WCAG/EAA compliance scanner as a solo product: enter a URL, get a free compliance score and top violations, then purchase a full professional PDF report with severity ratings and fix instructions. I used Next.js and TypeScript, with axe-core and headless Chrome, and Stripe guest checkout requiring no account.
APIDelta — AI-powered API Change Monitor (Add)
I designed and shipped an API dependency change monitor for engineering teams. It crawls third-party API changelogs (Stripe, Twilio, SendGrid), uses LLM classification (Claude API) to separate breaking changes from deprecations, and alerts teams via Slack, email, and HMAC-signed webhooks before issues reach production. It includes an MCP server exposing the catalog to AI agents.
Ticketing Platform — End-to-end SaaS
I delivered a full SaaS product solo: a Django API, a Next.js frontend, a React Native mobile app, and Terraform-managed multi-environment AWS infrastructure with Stripe payments — from architecture to production deployment.
