What I'm looking for

I am looking for a challenging role that fosters innovation and collaboration, where I can leverage my full-stack expertise to drive impactful projects.

I am a Senior Software Engineer with extensive experience in full-stack development, particularly in Java and JavaScript technologies. Currently, I work at ManyPixels, where I lead a team in migrating database schemas and implementing analytics events that enhance user interaction visibility. My technical guidance and code reviews ensure adherence to high coding standards and performance optimization.

Previously, I contributed to EbkTech as a Full-stack Engineer, where I designed and built applications using a Spring Boot-based microservices architecture. My focus on test-driven development and continuous integration has significantly improved the quality and stability of our software. I also have experience in optimizing applications for performance and resource efficiency, particularly in my role at EfexPay, where I developed solutions for security and fraud detection in banking transactions.
