AboutMe
I’m a tech lead and full-stack software engineer with over 5 years of experience building scalable, high-impact web applications. I specialize in JavaScript frameworks like React, Node.js, and Next.js, and I have a strong track record of delivering clean, efficient, and secure solutions across complex systems. In my current role, I lead development teams, oversee architecture decisions, conduct code reviews, and mentor developers to ensure both technical excellence and team growth. I collaborate closely with stakeholders to align technology with business goals, driving measurable value through smart, scalable solutions. Whether building high-performance APIs, optimizing user experiences for large-scale platforms, or leading cross-functional teams, I bring a balance of hands-on technical expertise and a strong product mindset. I'm always looking for opportunities to help teams innovate and turn ideas into reliable, maintainable software.
