Wizard AI

Staff Software Engineer
  • Shipped shareable product polls end to end: MySQL schema enforcing vote integrity, integration-tested TypeGraphQL API with scoped auth and scheduled lifecycle jobs, and React guest share flows.
  • Built favorites end to end: MySQL schema, integration-tested GraphQL API, MobX store, and UI.
  • Led the customer app's move from a fixed 430px mobile layout to desktop with the design team: shared breakpoints across 3 packages, consolidated 6 duplicated headers into one, and replaced legacy modals with a reusable drawer.
  • Built the sources drawer showing shoppers the reviews behind each AI recommendation, upgrading legacy data on read.
  • Raised Lighthouse accessibility on core screens from 82 to 95 (average) by initiating audits and fixing 38 WCAG failures across checkout, chat, product, gallery, and reviews; added jsx-a11y linting to the shared ESLint config.
  • Cut JavaScript downloaded on first load by 70% and first contentful paint by 59% (Lighthouse mobile) after finding the customer app served uncompressed assets, then enabling Cloud CDN compression in Terraform.

Commsor

Senior Full-Stack Engineer
  • Scaled network discovery from about 100 to tens of thousands of connections per person in under a minute, enabling live sales demos: replaced a slow graph-database crawl with a retryable Inngest + Elasticsearch pipeline over 700M+ profiles.
  • Owned the product platform end to end as founding engineer; designed the technical hiring process (take-home with live review) and hired and onboarded two engineers, growing in-house engineering from one to three.
  • Led the NextAuth to Better Auth migration after library workarounds caused silent sign-in failures, consolidating user tables; added workspace RBAC and PostgreSQL row-level security for tenant isolation.
  • Shipped the end-to-end introduction workflow in Next.js, with delivery via connected Google accounts.
