As a computer science and operations research engineer, I’ve always been driven by a passion for optimization and impactful problem-solving. This focus has shaped my journey from working with industry leaders like Airbus to founding JollyCoder in 2020—a specialized service in sustainable web design and development. I’m committed to empowering greentech companies and eco-conscious organizations to create efficient, user-friendly, and environmentally responsible digital experiences. My expertise encompasses web strategy, UX/UI design, and development with a sustainability-first approach. By merging technical skill and innovative thinking, I ensure that each project aligns with sustainable practices and contributes to a reduced carbon footprint. Whether starting from the ground up or optimizing existing platforms, I’m ready to help companies make a tangible impact online. I’m always keen to collaborate with like-minded partners who value the planet as much as their business goals. If your mission involves sustainability and forward-thinking digital solutions, let's connect and make your web presence a force for positive change 😄
