About
I’m a full-stack engineer with 5+ years of experience building and deploying production web applications using TypeScript, React, and Node.js, with a strong product mindset from architecture through delivery. I focus on reliable end-to-end features, clean system design, and measurable improvements that support real business outcomes.
I also work extensively on AI-powered products and integrations—building multi-agent systems, conversational agents, and automation workflows, including tool/function calling and external data aggregation. I’m comfortable with cloud infrastructure and DevOps practices (AWS/GCP, CI/CD, debugging, and observability), and I enjoy turning complex requirements into maintainable, scalable solutions.
