Commerce Bank Feb 2025 - Present

Sr. Full Stack Developer Kansas City, MO

• Designed and delivered Spring Boot microservices using Java 17, implementing clean API contracts, validations, and standardized error handling for banking workflows, which reduced integration errors and accelerated feature delivery

• Built REST APIs with Spring MVC, Spring Data JPA, and Hibernate; improved performance through query tuning and service-level optimizations.

• Implemented security with Spring Security, OAuth 2.0, JWT, and RBAC for banking operations, reducing unauthorized access incidents and meeting industry compliance standards.

• Developed event-driven processing using Kafka to support real-time transaction and notification flows, reducing processing time to under one second and improving system reliability.

• Improved latency using PostgreSQL indexing/query optimization and Redis caching, improving API response times by ~25%.

• Built UI features using React and TypeScript, delivering reusable components (forms, tables, modals) with consistent loading and error handling tied to REST APIs, which streamlined front-end development and enhanced user experience

• Deployed services on AWS using Docker and Kubernetes (EKS) and configured monitoring with AWS CloudWatch, providing real-time operational visibility that reduced incident response time

• Automated builds and deployments using Jenkins and GitHub Actions, improving release consistency.

• Used GitHub Copilot to accelerate routine implementation and unit test scaffolding; validated changes through code reviews and automated tests.

PNC Bank Jan 2024 - Dec 2024

Full Stack Developer Pittsburgh, PA

• Developed backend services using Java, Spring Boot, Spring Data JPA, and Hibernate for account and transaction workflows, resulting in faster transaction processing and more reliable account handling

• Built and documented REST APIs with Swagger/OpenAPI and added pagination and filtering, which reduced client load times and simplified data retrieval for consumers

• Implemented asynchronous processing using RabbitMQ to decouple long-running tasks and improve responsiveness.

• Managed schema updates and performance tuning in PostgreSQL and MySQL, adding indexes and optimizing queries, which decreased query latency and improved overall database performance

• Implemented application security using Spring Security, token-based authentication, and role-based access controls, which strengthened protection of sensitive data and reduced unauthorized access incidents

• Delivered UI screens using Angular and Material UI, building workflow pages with shared components, strong form validation, and consistent client-side error handling, which improved user experience and reduced form errors

• Supported deployments and integrations in GCP environments using Pub/Sub patterns and data/search use cases (BigQuery and Google Cloud Search), which enabled faster data access for internal teams

• Used GitHub Copilot to speed up service/UI implementation and unit test scaffolding, with reviews and CI checks to ensure correctness. Cigna Jan 2020 - Jan 2023

Software Developer USA

• Developed healthcare platform services using Java (Spring Boot), delivering secure REST APIs for claims and policy workflows.

• Implemented OAuth2 security with Spring Security, SSL/TLS, and token-based access, protecting the platform from unauthorized access

• Built batch jobs with Spring Batch for scheduled import/export and reporting tasks, reducing manual effort and ensuring timely data availability

• Implemented messaging using RabbitMQ and improved performance using Redis caching and efficient database access patterns.

• Built UI dashboards and workflow screens in React, integrating APIs with consistent state management and reusable components, which streamlined user interactions and lowered training time

• Supported CI/CD delivery with Jenkins and Docker containers, and validated performance using JMeter, resulting in more reliable deployments

• Worked with Azure DevOps to track work and run pipelines across releases, which streamlined release coordination and reduced deployment delays

• Used GitHub Copilot to speed up refactoring and test creation while maintaining quality through code reviews and automated testing. EDUCATION
