I’m Roy Levy, a senior full-stack engineer and software architect with 12+ years of experience building and scaling SaaS products, data platforms, and complex web applications end to end. I’ve led teams, owned architecture decisions, and shipped improvements that measurably boosted performance and maintainability—like consolidating many AWS Lambda endpoints into clean domain services. I work hands-on across modern TypeScript and JavaScript stacks (Angular, React, Next.js, Node.js) and data systems (PostgreSQL, MongoDB, Supabase/Neon, BI-ready read models). I also bring practical expertise in cloud, security, and system design, and I enjoy applying AI tools and APIs (e.g., OpenAI structured outputs and semantic search) to build smarter, safer product experiences.…I’m Roy Levy, a senior full-stack engineer and software architect with 12+ years of experience building and scaling SaaS products, data platforms, and complex web applications end to end.
