What I'm looking for

I am looking for a role that fosters innovation, collaboration, and growth in technology.

I am an experienced Software Engineer with over 7 years of hands-on experience in delivering innovative, scalable, and secure software solutions, particularly within the banking and financial sectors. My expertise lies in designing and implementing robust authentication, authorization, and corporate systems. As a Senior Software Engineer on a groundbreaking Open Finance project, I played a pivotal role in developing a secure and scalable authentication and authorization framework from the ground up, showcasing my knowledge of emerging payment technologies and their integration with financial systems.

Throughout my career, I have led the development of various projects, including a serverless Application Tracking System and Candidate Platform on AWS, where I utilized a wide range of AWS services to ensure a highly scalable and cost-effective platform. My technical skills extend to blockchain technology, where I contributed to an NFT Marketplace, and I have successfully implemented microservices architectures using Java, Spring, and Node.js. I am passionate about leveraging technology to enhance user experiences and drive efficiency in financial applications.
