I have a demonstrated ability to lead cross-functional teams, implement Agile methodologies, and embrace AI-powered development. I am passionate about performance, clean code, and creating intuitive user experiences.

Throughout my career, I have architected and delivered AI-driven B2B SaaS solutions, developed decentralized user systems, and optimized web performance for global e-commerce brands. My work has led to significant improvements in user engagement and system efficiency, such as designing a chatbot that increased task success rates by 60% and optimizing page load times by 25%. I thrive in collaborative environments and have a strong commitment to mentoring junior developers, ensuring that best practices are upheld across teams.
