What I'm looking for

I am looking for a role that challenges my skills, offers opportunities for growth, and fosters a collaborative environment.

I am a Senior Backend Developer with a strong focus on designing, developing, and optimizing high-performance applications using .NET and C#. My experience spans across various sectors, particularly in fintech, where I have successfully delivered scalable solutions that integrate third-party services and adhere to best practices in TDD and CI/CD.

Throughout my career, I have led the backend development of significant projects, such as the Vested App for FSDH Merchant Bank, where I integrated secure payment gateways and built microservices that enhanced system efficiency. My technical expertise includes microservices architecture, API development, and cloud technologies, which I leverage to create robust applications that meet user needs.

I am passionate about continuous learning and professional development, currently pursuing a Master's in Software Engineering while also holding a Diploma in Applied Data Science. I thrive in collaborative environments and enjoy mentoring junior developers, ensuring that best practices are followed in every project.
