I specialize in React, Next.js, TypeScript, and Node.js, with strong expertise in UI/UX, REST APIs, WebSockets, consumer payments, and self-custody wallets. My focus is on crafting clean, high-performance interfaces while integrating smart contracts, dApps, and third-party Web3 tools. I also leverage AI-assisted development workflows (e.g., Cursor) to accelerate delivery and enhance productivity.

At Rarible, I developed Rarible Studio, a proprietary self-serve CMS and API platform powering three core applications. I also integrated 14+ blockchains (including Ethereum, Base, Polygon, and Chiliz) into a white-label marketplace solution used by global brands such as Mattel, Lamborghini, McFarlane, and Disneyscaling to over 1M monthly users. Additionally, I led a React 18 migration, improved logging and security (achieving 80% greater error detection), and mentored engineers on front-end best practices and modern build pipelines.

Previously at Cazoo, I reengineered front-end flows, increasing homepage car-selling conversions by 600%, improving Web Vitals by 32%, and expanding observability coverage by 50%impacting a user base of over 3 million monthly visitors.

As the founder of andginja, I built genist.io, an AI-powered content engine, and developed a high-performance, SEO-optimized personal brand website that generated over 20 million interactions and led to collaborations with brands like TAP Air Portugal and Etihad Airways.

I also focus on Web3 security, having built tools that protected Discord communities from phishing attacks, maintaining zero major cybersecurity incidents over three years.
