At Concept Studio, I shipped production websites for global brands across fintech, tourism, branding, Web3, real estate, hospitality, and cultural institutions. I built responsive frontends with React, Next.js, and Vue, with Lighthouse scores of 90+.

I reduced average page load time by up to 30% through code-splitting, image optimisation, and Core Web Vitals tuning. I also developed Laravel and PHP backend services and REST APIs, and integrated Firebase for real-time features and authentication.

I led SEO setup and ongoing technical SEO across the portfolio, using Google products for tracking, indexing, and performance. I applied accessibility best practices and worked with designers in agile cycles.

Since May 2026, I’ve worked as a self-employed freelance Senior Full Stack Developer, delivering frontend and backend solutions with React, Next.js, Vue.js, and Laravel. I’m also expanding my portfolio with production-grade projects and use AI-assisted tooling to ship efficiently.
