I have a proven track record of leading AI-driven projects and implementing DevOps practices that enhance system performance and reduce deployment times.

Throughout my career, I have architected robust backend systems and developed responsive frontend applications that significantly improve user experiences. My role at Notion involved mentoring a team of developers, aligning engineering efforts with strategic goals, and introducing best practices that increased team velocity. I am passionate about clean, maintainable code and continuously seek to solve complex technical challenges while delivering impactful results.
