About me

Technical builder with hands-on experience across backend, full-stack, data, APIs, automation, and business systems. I turn ambiguous requirements into reliable software, integrations, internal tools, and workflows, and can own delivery from architecture to deployment.

I build reliable software systems that connect backend development, data, integrations, automation, and practical business needs. My core stack includes Python, TypeScript, Node.js, PostgreSQL, SQL, REST APIs, Docker, Linux, and cloud-based workflows. I work across system design, API integrations, database design, data modeling, internal tools, business process automation, and troubleshooting existing systems. I can take a project from ambiguous requirements through architecture, implementation, deployment, and iteration. I also have full-stack experience and can work across the frontend when a project requires end-to-end delivery, but my strongest areas are backend systems, data, integrations, and automation.
