WORK EXPERIENCES:

DELL TECHNOLOGIES July 2022 – Present

ROLE: Java Full Stack Developer

As a Java Full Stack Developer at Dell Technologies, I design, develop, and deploy enterprise-scale applications using Java (Spring Boot, Hibernate), React.js, Node.js, and RESTful APIs. I collaborate in an Agile/Scrum environment with distributed teams across global time zones, focusing on building cloud-native solutions on AWS while ensuring high performance, security, and scalability.

• Designed and implemented enterprise-grade applications with Spring Boot, React.js, and Node.js, ensuring modular, maintainable codebases and reducing feature development time.

• Built and deployed cloud-native microservices on AWS (EC2, Lambda, RDS, S3), improving scalability and supporting thousands of concurrent users without performance degradation.

• Established CI/CD pipelines using Jenkins, GitHub Actions, Docker, and Kubernetes, cutting deployment times from days to hours and minimizing manual errors.

• Optimized SQL queries and restructured PostgreSQL/MySQL schemas, reducing query execution time by 20% and improving end-user experience.

• Integrated and secured third-party APIs (authentication, payments, notifications) using OAuth2 and JWT, strengthening application security and compliance.

• Partnered with cross-functional teams in Agile sprints, collaborating across time zones to meet delivery commitments and align with business goals.

• Mentored junior developers, led code reviews and pair programming sessions, and enforced TDD/BDD practices to enhance team productivity and code quality.

• Automated testing with JUnit, Mockito, and Selenium, achieving higher test coverage and reducing post-release defects.

• Actively contributed to system monitoring and performance tuning, implementing logging and alerting with ELK stack to ensure system reliability.

Achievements: Delivered 10+ successful product releases, reducing downtime by 25%, improving application performance by 30%, and shortening deployment cycles from weeks to hours by automating CI/CD pipelines and migrating workloads to the cloud.

HP(Hewlett-Packard) August 2019 - June 2022

ROLE: Full Stack Developer

At HP, I developed customer-facing portals and enterprise applications using Angular, Node.js, Java (Spring MVC), and .NET Core, with deployments on Azure and AWS. I worked closely with business stakeholders, UX designers, and QA teams to deliver robust, user-friendly applications that met high availability and performance standards.

• Developed and maintained full stack applications with Angular, Node.js, Spring MVC, and .NET Core, improving user interaction and application reliability.

• Integrated RESTful and SOAP APIs for authentication, payment gateways, and notification services, accelerating delivery of business-critical features.

• Deployed enterprise applications on Azure (AKS, Cosmos DB, DevOps pipelines) and AWS (EC2, S3, RDS, SNS, SQS), ensuring scalability and disaster recovery.

• Designed and implemented Kafka-based event-driven architecture for real-time transaction processing, handling high concurrency with low latency.

• Automated regression and integration testing using JUnit, Mockito, and Selenium, reducing defect leakage into production by 35%.

• Collaborated with database teams to optimize Oracle and SQL Server queries, achieving 15% faster response times and supporting high-volume workloads.

• Participated in Agile Scrum ceremonies (stand-ups, sprint planning, retrospectives), ensuring sprint commitments were met with consistent on-time delivery.

• Worked with UX and QA teams to deliver user-centric solutions, improving usability scores and reducing support tickets.

• Documented technical workflows and best practices, while conducting code reviews to maintain consistency and quality across the codebase.

Achievements: Enhanced customer satisfaction by 15% through improved UI/UX features, reduced post-release defects by 35% with automation testing, and ensured 99.9% uptime with cloud-based deployments and real-time monitoring.
