Proven track record building and deploying production-grade applications using Next.js/React and TypeScript. Strong command of PostgreSQL and at least one backend runtime (Node/TypeScript). Direct experience with Supabase (Auth, Storage, Edge Functions, RLS, migrations) or a very similar Postgres-based BaaS is a strong plus. Actively use AI tools like Cursor, Devin, Copilot daily to accelerate implementation, improve test coverage, and explore design alternatives. Strong understanding of secure coding practices, authentication/authorization (OAuth2, OIDC), session management, and vulnerability mitigation in web apps. Deep experience designing relational schemas, optimizing queries, and working on high-volume, multi-tenant Postgres databases. Familiarity with software supply chain risks, SBOMs, CVEs, and vulnerability scanning principles. Experience running apps in the cloud, ideally AWS. Familiarity with containers (Docker) and orchestration (Kubernetes) is useful. Passionate about testing (unit, integration, end-to-end), CI/CD automation, and writing maintainable, well-structured code. Excellent communication skills and experience in cross-functional, remote teams.
