What I'm looking for

I’m looking to build end-to-end production SaaS where I can own architecture, shipping, and reliability—especially multi-tenant systems, real-time features, and AI integrations—while leveraging AWS and strong product thinking.

I’m a Senior Full-Stack Engineer with 4+ years of experience designing, building, and personally launching production SaaS products, multi-tenant platforms, and real-time systems. I’m equally strong across the stack—from Laravel backends and REST APIs to React + Inertia.js frontends—with hands-on ownership of cloud infrastructure on AWS, plus deep experience shipping integrations and high-concurrency platforms.

I take full ownership from idea to production: I’ve architected and shipped multi-tenant domain & hosting SaaS, built a Master SSO Identity Provider (IdP) with secure token exchange, and delivered AI-driven domain discovery that reduced manual search time significantly. In previous roles, I delivered 1,500+ production REST APIs for real-time ride-sharing, engineered WebSockets/Socket.io live tracking and matching, improved release cycles by cutting them from hours to minutes via CI/CD, and introduced AI-assisted development workflows that increased team delivery velocity by up to 10x.
