I’m a Senior Software Engineer with 9+ years of experience building SaaS platforms, fintech applications, and enterprise systems. My main expertise is in React, Next.js, Node.js, Laravel, and AWS, and I’ve delivered projects ranging from real-time financial alerting platforms at Mercury Development to large-scale digital systems at JPMorgan Chase that served millions of users. I also have strong experience in databases (PostgreSQL, MySQL, MongoDB), CI/CD pipelines, and microservices architecture. What makes me stand out is my ability to take end-to-end ownership — from designing intuitive frontends to architecting scalable backends — while always keeping the end user in mind. I thrive in both startup and enterprise environments and enjoy solving complex problems with clean, reliable solutions.
