I’m a Junior full-stack developer with hands-on experience delivering real production projects for clients. I enjoy problems that have a visible impact, and I take pride in shipping work that performs well and looks good doing it.

Currently, I’m working as a Junior Developer (full-time) at Iris Network Systems, where I progressed from a freelance contract through a 6-month internship into a permanent role. I continue to own the frontend codebase for irisns.com—shipping features, improving performance, and collaborating directly with the team on design decisions.

Before that, I built irisns.com from scratch during my internship, becoming the sole frontend owner and keeping the site running smoothly in production. Earlier freelance work also involved managing the frontend codebase post-launch, including performance improvements and new feature delivery.

I also built an AI-Visibility SEO & performance scanner, integrating React/Vite/Tailwind on the frontend with Node.js scripts on the backend to crawl pages and surface technical SEO issues in a red/amber/green dashboard. I cut homepage load times to ~2s LCP for real local businesses, and refined the tool through direct feedback—so I’m always focused on measurable outcomes, not just completed features.
