Achyuth Dondapati

Sept 2025 --- Present

• Led the modernization of a legacy JSP/Servlet-based MVC application into a Spring Boot–driven service-oriented architecture, improving scalability, modularity, and deployment efficiency across the ASPEN platform.
• Refactored tightly coupled presentation logic by decomposing legacy JSP/Servlet flows into Spring MVC controllers and developing React-based interactive UIs, significantly improving user experience and maintainability.
• Designed and implemented RESTful APIs using Spring Boot to support real-time interactions between modern React frontends and backend eligibility and productivity services.
• Contributed to the IMPACTS productivity platform, developing Spring Boot backend services and React-based gamification dashboards to track case worker performance, task completion metrics, and workflow efficiency.
• Integrated Amazon Connect task-based routing to enable asynchronous task processing and intelligent task assignment for case workers, improving workload distribution and reducing manual task handling.
• Integrated RabbitMQ as an asynchronous messaging layer between Spring Boot microservices, enabling reliable event-driven communication for case management workflows and decoupling task routing logic from core eligibility services.
• Worked on Amazon Connect Task Control Panel integrations, enabling backend services to publish, update, and track tasks routed to case workers based on skill sets, availability, and priority.
• Implemented backend workflows to synchronize Amazon Connect task events with internal case management services, ensuring real-time task status updates and seamless user experience for case workers.
• Optimized complex SQL queries and indexing strategies in MySQL/Oracle databases, reducing query latency by approximately 25% and improving performance of eligibility and productivity workflows.
• Implemented JWT-based authentication and Spring Security filters, enforcing secure access control across microservices and protecting sensitive eligibility and task data.
• Developed reusable, high-performance React components using hooks and centralized state management, reducing UI complexity and enabling consistent patterns across ASPEN and IMPACTS applications.
• Built centralized exception handling, logging, and observability mechanisms using Spring AOP, SLF4J, and structured logs to improve production monitoring and troubleshooting.
• Ensured system stability through unit, integration, and API testing using JUnit, Mockito, and Postman, supporting safe feature delivery during continuous modernization efforts.

Jan 2023 --- Sept 2025

• Migrated monolithic applications to a cloud-ready microservices architecture using Spring Boot and Node.js, improving service decoupling, scalability, and deployment efficiency by 40%.
• Developed secure, high-throughput RESTful APIs using Java (Spring Boot) and Node.js/Express, enabling seamless communication across distributed microservices.
• Built Node.js services for asynchronous processing, API gateway routing, and real-time data handling, improving system responsiveness and reducing backend load.
• Implemented middleware in Node.js for request validation, rate limiting, and logging, strengthening API reliability and security.
• Designed event-driven communication between microservices using Apache Kafka for asynchronous message streaming, improving system decoupling and enabling reliable real-time data processing across distributed services.
• Actively integrated AI coding copilots to accelerate development, auto-generate boilerplate code, optimize service design patterns, and improve testing workflows.
• Leveraged Generative AI tools to refactor legacy modules, produce rapid POCs, auto-generate Swagger/OpenAPI specifications, and validate API schemas.
• Developed and maintained Python-based ETL pipelines, log-processing scripts, and automation workflows, improving operational efficiency.
• Integrated JWT and OAuth 2.0 for authentication and authorization across Spring Boot and Node.js services, strengthening platform-wide security.
• Deployed containerized applications using Docker on AWS EC2 and automated CI/CD pipelines using Jenkins, achieving a 50% reduction in deployment cycles.
• Optimized MongoDB, PostgreSQL, and MySQL queries by refactoring schemas, creating indexes, and improving data access patterns, increasing performance by 25%.
• Built modular, reusable UI components using React and implemented backend presentation logic with Spring MVC, improving maintainability and reducing development time.

July 2020 --- Aug 2021

• Developed scalable microservices using Spring Boot and Spring MVC, applying modular design principles for better maintainability.
• Built interactive front-end components with React and Material-UI, ensuring responsive design across web platforms.
• Automated application deployment using Jenkins, Docker, and Shell scripts, cutting manual work and improving DevOps efficiency.
• Wrote and optimized SQL and NoSQL queries, resulting in 20% faster response times for data-heavy endpoints.
• Used Splunk to monitor logs and debug production issues, reducing mean time to resolution by 60%.
• Collaborated in Agile teams, participating in daily stand-ups, sprint planning, and code reviews, ensuring timely and quality releases.

Dec 2019 --- May 2020

• Contributed to the design and development of full-stack applications using Java and Spring Boot, focusing on backend logic and service integration.
• Implemented CRUD operations with Spring JPA and supported database schema design in Oracle and PostgreSQL.
• Assisted in building responsive UI screens with JavaScript, HTML5, and CSS3 to enhance user experience.
• Created SQL queries and stored procedures to support reporting features and application workflows.
• Gained hands-on experience with version control (Git) and issue tracking (Jira) in Agile sprints.
• Supported the team in writing unit test cases with JUnit and debugging application issues during QA cycles.
