I am an experienced System Analyst with over two decades of experience designing and optimizing systems in the banking sector, primarily at HSBC. Throughout my career, I’ve developed robust, scalable solutions that improved performance, reduced operational costs, and enhanced data workflows for high-impact processes. Driven by a passion for continuous learning and staying at the forefront of technology, I transitioned into Full Stack Web Development, completing an intensive 700-hour Bootcamp at Henry. Since then, I’ve continued to grow my technical skill set with advanced training in modern frameworks such as React.js. With a unique blend of deep legacy systems knowledge and up-to-date full stack capabilities, I bring a holistic and adaptable perspective to software development — always focused on efficiency, quality, and business value.
