About

I'm pioneering how developers work with AI—not just using it, but teaching others to harness its full potential. As a GitHub Copilot Trainer, I lead workshops that help development teams adopt AI coding assistants effectively, adapting training to real-world challenges. I also organize hackathons focused on AI Coding Assistants and Agentic AI with n8n, creating spaces where developers can experiment with cutting-edge technologies and explore AI-First SDLC practices. At Accenture, I build scalable frontend solutions with 6+ years of React expertise, along with Node.js cloud development experience. I specialize in creating resilient, composable components using React, TypeScript, and JavaScript—consistently delivering projects that meet both technical requirements and tight deadlines. Beyond writing code, I'm passionate about growing talent. I've mentored junior developers at Accenture, Modis, and ABATON, sharing best practices while learning from fresh perspectives. I'm a strong believer in positive reinforcement as the key to unlocking peak performance—celebrating wins, building confidence, and creating an environment where teams naturally deliver their best work. What drives me: Staying at the intersection of software engineering and AI innovation, while helping others navigate this rapidly evolving landscape. Always open to new opportunities, to connecting with fellow developers, teams exploring AI adoption, or anyone interested in collaborative learning through hackathons and workshops.
