Senior full-stack engineer with 5+ years of experience building production-ready, multi-tenant SaaS products end to end—from responsive UI and REST API design to Stripe billing, role-based authentication, admin tooling, analytics, deployment, and operational handover. I focus on secure AI integrations (OpenAI/Anthropic), tenant-scoped data isolation, structured outputs, usage controls, retries, and observable production pipelines. I partner with product, design, security, and customer-facing teams to deliver MVPs with clear acceptance criteria, manage platform risk, and keep systems reliable through monitoring, runbooks, testing, and incident-ready operational practices.…Senior full-stack engineer with 5+ years of experience building production-ready, multi-tenant SaaS products end to end—from responsive UI and REST API design to Stripe billing, role-based authentication, admin tooling, analytics, deployment, and operational handover.
