Luxury Jewelry E-Commerce Website – Gemsparx Front-End & Full-Stack Developer (React & Node.js) Gemsparx is a luxury jewelry marketing and e-commerce website designed to showcase diamonds, fine jewelry, and custom design services with a high-end user experience. I developed this project using React for a fast, responsive front end and Node.js for backend functionality. The focus was on creating a visually elegant, conversion-friendly interface while maintaining performance, scalability, and clean code architecture. The website features structured product categories, promotional sections, custom design workflows, and a modern UI optimized for both desktop and mobile users. This project demonstrates my ability to build premium marketing websites that align with luxury brand aesthetics and business goals.

I help teams and founders ship reliable, scalable full-stack applications from early MVPs to production systems used at scale. As a Senior Full-Stack Developer, I focus on: Building clean, maintainable frontends with strong UX foundations Designing resilient backends, APIs, and data models Making pragmatic tech decisions that hold up over time Shipping fast without cutting corners What I typically work on: SaaS platforms & internal tools Complex dashboards and data-driven apps API-first systems and integrations Performance, refactors, and technical debt cleanup I’m opinionated about code quality, architecture, and ownership but flexible about tools and stacks when the problem calls for it. If you need someone who can own features end-to-end, communicate clearly, and think beyond just “making it work,” let’s talk.
