About

Built for teams that need execution, ownership, and calm delivery.

I am strongest in roles where a team needs both execution and ownership: modernizing legacy systems, shipping features against real deadlines, and keeping product quality high while infrastructure scales.

Over the last 5+ years, I have worked on systems for investment products, national-scale data collection, healthcare operations, e-commerce, and service businesses. That range matters because it taught me how to adapt quickly without lowering quality.

I am comfortable taking a feature from planning to production: shaping the interface, building the API layer, handling data concerns, and supporting deployment and monitoring after release.

Capabilities

What I can own across a product team.

Backend and platform delivery

Designing APIs, authentication flows, payment integrations, and maintainable service layers for production systems.

  • Node.js, NestJS, Express.js, Laravel, PHP
  • REST APIs, admin systems, integrations, data workflows
  • PostgreSQL, MySQL, MongoDB, Firebase

Frontend and product UX

Building fast interfaces that match business workflows, reduce friction, and stay maintainable after launch.

  • Next.js, React, TypeScript, Tailwind CSS
  • Responsive UI systems, dashboards, marketing sites
  • SEO-aware delivery and performance-focused rendering

Cloud, operations, and reliability

Shipping features is only half the job. I also care about uptime, observability, and practical deployment workflows.

  • AWS, Ubuntu, Linux, Docker, Nginx
  • Datadog, CI/CD, incident visibility, production support
  • Legacy migrations and infrastructure handoff
