About Me

I'm a software engineer with over five years of experience focused on process design, analysis, and optimization. Throughout my career, I’ve developed a strong foundation in solving complex problems and continuously improving workflows to enhance performance and reliability. My work has often involved digging into the details of systems to understand how they work, identifying bottlenecks or vulnerabilities, and designing thoughtful, scalable solutions that drive measurable impact. Over time, I’ve become particularly interested in the intersection of software engineering and cybersecurity. As systems become more interconnected and threats more sophisticated, I see an urgent need for secure, efficient, and resilient infrastructure—and that’s exactly where I want to contribute. I'm passionate about building solutions that not only work well but are also robust against evolving risks. With a mindset rooted in curiosity and a commitment to continuous learning, I’m excited to bring my skills and experiences to teams that are tackling these challenges head-on.
