Technical delivery

Built, deployed, and maintained like a real product.

This portfolio is intentionally simple, fast, and production-hosted — with each new project added as a clearer proof point instead of a temporary experiment.

Production

Custom domain + HTTPS

Deployed on Cloudflare Pages with a personal domain, automatic TLS, HTTP-to-HTTPS handling, and canonical www-to-apex redirects.

Next collaboration

Open to data, AI, and product-building opportunities.

I am focused on junior data analyst opportunities, practical AI workflows, and projects where clear communication, structured problem solving, and shipping discipline matter.

Portfolio update system New projects are added as concise case-study cards: problem, build, stack, status, result, and professional signal. The goal is a site that looks more complete after every shipped artifact.
