 I’m a Senior Backend Software Engineer with more than 15 years of experience building business-critical systems across government, fintech, and enterprise organizations. I graduated with a Bachelor's degree in Information Technology in 2011 and, after gaining several years of hands-on industry experience, completed an MBA in SQL Server Database Management in 2017. Throughout my career, I have always been passionate about understanding not only how to build software, but also how technology can solve complex business problems.

My career started with software development, database administration, and data engineering, giving me a solid foundation in system architecture, data modeling, and performance optimization. Over the years, I naturally took on more technical ownership, leading the design of complex business rules, modernizing legacy platforms, and working closely with business stakeholders to translate challenging requirements into reliable software solutions.

In recent years, I have specialized in backend engineering for mission-critical payment systems. I've worked on tax and audit platforms, payment processing solutions, large-scale backend applications, and legacy modernization initiatives. Today, I help build an Anti-Corruption Layer (ACL) based on Domain-Driven Design principles, enabling communication between modern payment services and legacy platforms while supporting an incremental migration strategy. Along the way, I have also led production incident investigations, designed resilient integration strategies, and contributed to distributed systems running at scale.

My technical expertise includes Python, Kotlin, Java, PostgreSQL, AWS, Docker, Kubernetes, Terraform, distributed systems, and software architecture. I enjoy collaborating with cross-functional teams, mentoring engineers, and designing solutions that are scalable, maintainable, and resilient.
