Services

Website builds are the core. Apps and automation come in when they make the site more useful.

Websites (Design + Build)

Custom sites that load fast, look modern, and work cleanly on mobile.

  • Portfolios, landing pages, small business sites
  • Responsive layout + basic SEO setup
  • Deploy + domain help if needed

Website Upgrades

Fix what’s messy: layout issues, speed, mobile polish, and general cleanup.

  • Performance + UX improvements
  • Mobile responsiveness fixes
  • Refactors without rewriting everything

Lightweight Web Apps

When the site needs real functionality: forms, dashboards, portals, APIs.

  • Simple client tools and dashboards
  • Backend + database when appropriate
  • Clean architecture, not overbuilt

About

I’m a developer who learned by building real things, breaking them, and making them better. I finished my CS degree and I’m currently doing my master’s through Georgia Tech.

I like straightforward builds: clean UI, solid structure, fast pages, and no unnecessary complexity. If you want something polished and reliable, I’m probably a good fit.
