  I support bank-wide transformation by improving workflows, reducing operational risk, and building automation tools using M365 and PowerApps. I translate business needs into practical system solutions, including PRDs and error-logging tools, to enhance accuracy and strengthen control processes. My work helps streamline operations, standardize processes, and ensure better visibility for stakeholders. I worked across business, IT, and compliance teams to turn operational requirements into data-driven system enhancements. I supported fraud detection improvements, strengthened regulatory reporting (SLIK, IFRS), and used SQL to provide insights for decision-making. My role focused on problem-solving, cross-functional coordination, and delivering accurate, reliable system solutions.
