Verizon - Contract Irving, TX January 2024 – Present Full Stack Java Developer

• Built and maintained Java/Spring Boot microservices for Verizon's network Operations Support Systems (OSS) to enable real-time topology monitoring and fault visibility across the DFW telecom infrastructure, supporting over 50 network nodes and 10+ operations teams, using Spring Boot, Angular, Docker, and Kubernetes.

• Designed and exposed RESTful APIs to integrate internal control dashboards with downstream network management systems, supporting incident management, maintenance scheduling, and service order workflows across Verizon's wireline and 5G infrastructure.

• Built Angular/TypeScript front-end dashboards to surface live network metrics and system health data, improving fault detection visibility for network operations engineers.

• Integrated Apache Kafka for asynchronous event streaming between network subsystems, improving decoupling and reliability of telemetry data pipelines across OSS components.

• Configured and maintained CI/CD pipelines using GitHub Actions and Jenkins, automating build, test, and deployment workflows and reducing manual release effort by approximately 60%, accelerating delivery cycles for network-facing tools.

• Integrated automated test suites using JUnit, Mockito, and Jest to validate API contracts, business logic, and UI workflows, improving regression coverage ahead of production releases.

• Implemented structured logging and monitoring across backend services to support real-time fault detection, post- incident analysis, and SLA adherence within Verizon's network operations environment. Lavner Education — Rice University Houston, TX May 2023 – December 2023 Software Engineer

Designed and delivered a structured Java programming curriculum for students to build functional backend applications from scratch, using OOP principles, REST API concepts, and project-based learning aligned to real-world software workflows.

Mentored 9+ students simultaneously through debugging sessions and code reviews across Java, Python, and C++, using a step-by-step diagnostic approach to build independent problem-solving skills.

Troubleshot, repaired, and automated software updates across 80+ development workstations, saving approximately 1 hour per machine and ensuring consistent lab environments for all sessions.

Developed and demonstrated web applications using HTML, CSS, JavaScript, and React to teach responsive web design principles, giving students exposure to full-stack development workflows.

Streamlined classroom inventory management using SQL-based tracking, reducing equipment loss by 10% and improving weekly report accuracy from 75% to 90%.

Configured and maintained IDE environments, build tools, and runtime setups across lab machines, diagnosing setup failures in real time to minimize session disruption. Vantage Health Plan - Contract (now BCBS Louisiana) Monroe, LA January 2022 – May 2023 Junior Java Developer

• Developed full-stack healthcare platform features to streamline clinical and administrative workflows for end users, using Java, Spring Boot, Angular 14, and JWT-based authentication across microservices deployed on PCF.

• Built Angular 14 front-end components including services, routing, dependency injection, directives, and two-way data binding to support clinical and administrative application modules.

• Automated CI/CD pipelines using Jenkins, Docker, Kubernetes, and Pivotal Cloud Foundry (PCF), managing microservice deployments across dev, test, and production environments and cutting average deployment time by approximately 40%.

• Configured JMS messaging on WebSphere for asynchronous communication between healthcare subsystems, improving decoupling and reliability of critical workflows.

• Designed application architecture using UML diagrams (Use Case, Class, Sequence) and participated in Agile Scrum and Kanban ceremonies to track delivery and resolve blockers.

• Applied TDD practices with JUnit and Git-based version control to maintain code quality and support collaborative development across a cross-functional engineering team. LeapFrog Technology Remote July 2020 – November 2021 Junior Software Engineer

Contributed to full-stack product development for client-facing applications to accelerate feature delivery and improve system reliability, using Java, Spring Boot, REST APIs, and Angular across Agile sprint cycles.

Built and integrated RESTful APIs to support seamless communication between backend services and front-end product modules, following enterprise-grade coding standards and clean architecture principles.

Assisted in containerizing application services using Docker and supported cloud deployments on AWS, ensuring consistent environments across development and staging pipelines.

Wrote unit and integration tests using JUnit and Mockito to validate backend logic and API behavior, maintaining test coverage and code quality ahead of client deployments. EDUCATION
