I am a software engineer with 10+ years of experience turning complex challenges into scalable, maintainable, customer-focused solutions. I build and harden production SaaS platforms with a strong focus on backend and cloud infrastructure, and I’m proficient in React, TypeScript, PostgreSQL, and cloud platforms across AWS and GCP. I have led identity management work in large migrations, performed codebase audits, and taken systems from early-stage to production-ready, all while mentoring teams and producing clear technical documentation. I enjoy designing maintainable architectures, guiding teams toward reliable outcomes, and delivering AI-assisted workflows that improve throughput. I’m currently exploring retriever-augmented generation (RAG) approaches and contributing to end-to-end AI-enabled product narratives. I’m available to start immediately and collaborate closely with founders to ship impactful features.
