Led feature development across multiple teams and services, promoting the use of High-Level Design diagrams and a contract-first approach to accelerate the delivery of high-quality features.

Designed and implemented a centralized locations service, streamlining address auto-completion and georeverse functionality across microservices, significantly enhancing operational efficiency.

Drastically improved performance of a core (L5) service, reducing endpoint execution time by 50% through query analysis and the implementation of additional indexes.

Identified and resolved bottlenecks in critical services using New Relic metrics, implementing robust load monitoring and auto-scaling mechanisms to prevent production incidents.

Performed an in-depth analysis of Neo4j database performance, leveraging internal tools and Neo4j business customer support. Optimized database computation speed to ensure seamless integration of various internal banking services, enhancing overall system efficiency and performance.

Implemented a tree traversal algorithm to efficiently identify differences between elements and facilitate streamlined updates within a single transaction. This enhancement improved data manipulation processes, increasing system reliability and transactional integrity.

Led the migration to a hexagonal architecture design, creating a modular and extensible codebase. Leveraged Dependency Injection (DI) for improved component reuse and extension. This transition enhanced code maintainability, scalability, and alignment with best practices for software design.

Led the research and development of a cutting-edge microservices tech stack, establishing a reusable template for future projects. Integrated Kafka for real-time data streaming and processing, enhancing system agility and scalability. Incorporated Elasticsearch to enable efficient and scalable search functionality, ensuring optimal performance.

Implemented Single Sign-On (SSO) authentication using Keycloak, ensuring secure and seamless access for users across multiple services. Integrated role management functionalities to effectively control user permissions and access levels.

Championed the adoption of contract-first development using OpenAPI/Swagger, significantly reducing boilerplate code, accelerating development time, and enabling non-blocking development across multiple teams by providing a clear and standardized API contract.

Developed robust validation mechanisms for a Function as a Service (FaaS) platform, ensuring data quality and API stability for end-users. This initiative enhanced reliability and usability, delivering a seamless experience while maintaining platform integrity.
