About

I am a software developer with over 12 years of experience, currently serving as Assistant Team Lead Developer at Uridium Technologies Limited on the Sterlingpro project since February 2024. My career began in 2011 with internships and graduate trainee roles, progressing through various software development positions in financial and technology sectors. My work spans backend and frontend development using C#, Java, VB.Net, AngularJS, Bootstrap, and Flutter. I have built and maintained REST APIs, SOAP services, worker and windows services, and migrated monolithic architectures to microservices. I have experience with database management systems including SQL Server and Oracle, and mobile app development using Flutter and Android Studio.

What I'm looking for

I am looking for a role where I can contribute to the design and delivery of scalable, high-quality software solutions while collaborating with talented engineers and cross-functional teams. I enjoy working in environments that value technical excellence, continuous improvement, and innovation. As a Senior Software Developer, I am particularly interested in opportunities to take ownership of complex projects, mentor junior developers, and participate in architectural decisions.
