Milos Dzeletovic

Led development of scalable frontend features for secure banking and financial platforms using React and TypeScript, delivering responsive interfaces for transaction workflows and internal tools. Built reusable component libraries and maintained consistent UI patterns across multiple products to improve development speed and long-term maintainability. Collaborated with backend engineers to define and consume REST APIs, ensuring reliable integration of financial data with accurate state handling and smooth user interactions. Optimized performance through component refactoring, lazy loading, memoization, and efficient rendering strategies. Contributed to code reviews, technical planning, and frontend architecture discussions to establish clean coding standards.

Engineered a high-volume payment gateway with RESTful APIs and back-end services in Java, Go, and Spring Boot to support reliable transaction workflows across heterogeneous banking systems. Built and maintained production micro-services with Spring Security, optimized data access with Hibernate and SQL, and drove end-to-end feature delivery from requirements through architecture, implementation, and release; leveraged Jira tracking and Git-based workflows to maintain quality. Diagnosed production defects and hardened error handling and logging to improve reliability for downstream consumers.
