About Me

Senior Full-Stack Developer & Junior Security Analyst with deep expertise in IoT systems, fintech solutions, cybersecurity, and modern web development. Based in Haiti, serving clients worldwide.

I'm a passionate full-stack developer who thrives on solving complex technical challenges. My journey in software development has led me to specialize in two critical areas: IoT systems and fintech solutions.

What sets me apart is my experience architecting real-time systems that handle hundreds of concurrent connections and thousands of daily transactions. I've built banking integrations that process payments for thousands of users and IoT platforms that manage smart meters across entire cities.

I'm passionate about creating solutions that scale, whether it's a WebSocket architecture handling 300+ concurrent devices or a payment system processing thousands of transactions. My goal is to join a team where I can leverage this unique combination of skills to build the next generation of digital products.
