About

I’m a specialized Full Stack Developer with 5 years of experience as an independent contractor. My core expertise lies in React.js/Next.js and Node.js, but I’ve had the chance to work across a variety of frameworks like WordPress, Salesforce, Shopify, Hugo, and HubSpot to tailor unique solutions for my clients. I enjoy translating design concepts into high-performance applications and integrating third-party services to automate workflows and enhance efficiency.

I’m also skilled in performance tuning and SEO best practices to improve usability and visibility. I’m a quick learner, always excited to embrace new technologies, and I’m committed to working closely with clients and teams to ensure successful outcomes.
