Building Resilient
Digital Solutions
Hi, I'm Raja Karuparthi, a Software Engineer with 10 years of experience designing and delivering enterprise applications, microservices, and AI-powered engineering agents.
About Me
I am a Software Engineer with 10 years of experience designing and delivering enterprise applications, microservices, distributed systems, and cloud-native solutions. Based in Dallas, Texas, I specialize in architecting high-volume, event-driven platforms and integrating AI-powered engineering agents to optimize productivity.
With deep expertise in the Java ecosystem (Spring Boot, Spring Cloud, Hibernate, JPA) alongside Kafka, Redis, Oracle, and AWS, I build scalable systems that handle high throughput. I have a proven track record of modernizing legacy architectures and deploying robust pipelines that streamline business-critical operations.
Work Experience
Software Engineer
Verizon- Architect and develop enterprise-grade microservices supporting Revenue Assurance (REVO) and Mobile Telephone Application System (MTAS) platforms using Java, Spring Boot, Oracle, Redis, IBM MQ, Oracle AQ, and Apache Camel.
- Maintain and enhance 14+ production microservices serving thousands of users and supporting mission-critical telecommunications operations.
- Built high-throughput event-driven systems processing 100+ transactions per second using IBM MQ, Oracle AQ, Redis, Apache Camel, and multithreaded Java processing.
- Developed MTAS integrations handling activation, provisioning, and mobile network transactions from external partners including Charter and Comcast.
- Designed and implemented secure REST APIs using OAuth2, OpenAPI, and Spring Security while maintaining 90%+ test coverage.
- Modernized legacy services by upgrading applications to JDK 17 and Spring Boot 3.x, improving security, maintainability, and operational performance.
- Developed complex SQL and PL/SQL scripts for data extraction, reconciliation, reporting, production support, and root-cause analysis across Revenue Assurance and MTAS platforms.
- Built Python-based data collection, processing, and reporting utilities that automated manual workflows and improved operational visibility.
- Automated fallout detection and operational reporting through Python scripts that analyzed large datasets, identified transaction anomalies, and generated actionable insights for business and engineering teams.
- Leveraged Oracle SQL, PL/SQL, and Python to perform large-scale data analysis, trend identification, and troubleshooting of revenue-impacting incidents.
- Architected AI-powered engineering agents using Claude, Pinecone, and Retrieval-Augmented Generation (RAG) to analyze approach documents, search code across 5 repositories, perform impact analysis, and generate implementation-ready code recommendations.
- Delivered approximately 30% improvement in engineering productivity by automating requirement-to-code discovery, code generation, and implementation workflows.
- Architected and developed AI-powered software engineering agents using LangChain, Claude, Pinecone, and Retrieval-Augmented Generation (RAG) to automate requirement analysis, code discovery, and implementation planning.
- Built agentic workflows that analyze project approach documents, perform semantic search across enterprise Git repositories, identify relevant code components, and generate implementation-ready code recommendations, improving developer productivity by approximately 50%.
- Leveraged Python, statistical analysis, and machine learning techniques to analyze device and line promotion drop patterns, enabling early identification of revenue-impacting fallouts and improving operational decision-making.
- Designed and implemented RAG pipelines leveraging vector embeddings, Pinecone vector databases, and contextual retrieval strategies to enable accurate knowledge discovery from technical documentation, source code, and architectural artifacts.
Software Engineer
Charter Communications- Designed, developed, and maintained enterprise-grade Java/Spring Boot microservices supporting Spectrum Mobile and customer account management platforms.
- Led development of the Spectrum Mobile 2 (SM2) NextGen BIS system, delivering contract-first REST APIs and scalable backend services for account management workflows.
- Built and optimized microservices using Spring Boot, Hibernate, and REST APIs, improving application scalability, maintainability, and performance.
- Integrated Redis caching solutions to reduce direct dependencies on the Amdocs billing platform, significantly improving API response times and reducing backend load.
- Implemented Apache Kafka-based event-driven architectures to enable reliable inter-service communication and distributed processing.
- Developed solutions supporting Phone Balance Buyout (PBB), Go-To-Market (GTM), and Biller Call Reduction initiatives, improving operational efficiency and customer experience.
- Managed and mentored a team of four engineers, coordinating development activities, conducting code reviews, and ensuring successful project delivery.
- Built CI/CD pipelines and containerized deployments using Jenkins and Docker, accelerating release cycles and improving deployment consistency.
- Developed Python-based auditing and reconciliation tools to analyze large billing datasets, identify discrepancies between Charter and Amdocs systems, and automate reporting processes.
- Participated throughout the full software development lifecycle (SDLC), including requirements analysis, design, development, testing, deployment, production support, and performance optimization.
ERP ANALYST
Sam Houston State University- Collaborated with the IT department to support and maintain the campus-wide Enterprise Resource Planning (ERP) system, ensuring smooth operations for university services and student administration.
- Engineered end-to-end CI/CD solutions using Jenkins, Terraform, Ansible, Selenium, and Infrastructure-as-Code practices, automating build, testing, deployment, and environment provisioning across enterprise applications.
- Supported the Banner ERP system, a comprehensive suite of enterprise applications for student information, human resources, and financial management used across the university.
- Developed and maintained custom solutions using PHP, Python, and Java to extend Banner system functionality and integrate with other campus systems.
- Managed source code repositories and implemented version control best practices using Git, facilitating collaborative development and efficient code management.
