Senior Full-Stack Java | Spring Boot | AWS | React | AI Integration | Security Hello! I'm Deepak Kumar, a Senior Software Engineer and Full-Stack Developer with 8+ years of professional experience building scalable backend systems, cloud-native applications, APIs, and modern web applications. I specialize in Java, Spring Boot, Spring Security, React, AWS, microservices, and cloud-native development, with a strong focus on building secure, reliable, high-performance applications. After several years away from Upwork, I'm now actively returning to the platform and focusing on helping businesses build and modernize their software using modern Java/Spring technologies, cloud platforms, AI integrations, and secure full-stack architectures. 🚀 What I Can Help You Build Enterprise Java & Spring Boot applications RESTful APIs and microservices Secure applications with Spring Security OAuth 2.0, OpenID Connect, JWT and SSO React-based web applications and dashboards AWS cloud-native applications Docker & Kubernetes deployments CI/CD pipelines and DevOps automation AI/LLM integrations into existing applications AI-powered features, APIs and automation Database design and optimization High-performance and highly scalable systems Legacy application modernization Third-party API integrations Real-time applications using WebSockets Event-driven architectures with Kafka, Kinesis, RabbitMQ, etc. 💻 Core Technology Stack Backend Java 8/11+ Spring Boot Spring Framework Spring Data Spring Security Hibernate / JPA REST APIs Microservices WebSockets SOAP / Web Services Frontend React JavaScript HTML5 / CSS3 Bootstrap Thymeleaf Security Spring Security OAuth 2.0 OpenID Connect JWT SSO LDAP / CAS Role-based access control API security Cloud & DevOps AWS Google Cloud Platform (GCP) Docker Kubernetes ECS Lambda API Gateway CloudFront Route 53 SQS / SNS DynamoDB S3 Athena Redshift Aurora CI/CD Jenkins Bamboo CircleCI SonarQube Databases PostgreSQL Oracle MySQL MongoDB Cassandra Redis DynamoDB Redshift Athena / S3 Messaging & Streaming Apache Kafka AWS Kinesis RabbitMQ Apache Camel Event-driven architectures 🤖 AI & Modern Application Development I'm particularly interested in helping companies bring AI capabilities into existing Java/Spring applications rather than rebuilding everything from scratch. Examples include: Integrating LLM/AI APIs with Spring Boot AI-powered REST APIs Intelligent search and document processing AI assistants and chat functionality RAG-based application architectures Connecting AI services with existing enterprise systems AI workflow automation Secure AI integrations Building React interfaces for AI-powered applications ⚡ Performance & Reliability I also have experience analyzing and improving application performance using tools such as: JMeter JProfiler AWS X-Ray Gatling GTMetrix I focus on identifying bottlenecks across the application, database, API, infrastructure, and cloud layers rather than treating performance problems at only the code level. ⭐ Why Work With Me? Quality First: I focus on writing maintainable, production-ready code rather than simply making something work. Problem Solving: I enjoy debugging complex problems, understanding the root cause, and designing practical solutions. Clear Communication: I believe good communication is just as important as good code. I keep clients informed about progress, challenges, and technical decisions. Security Mindset: Security is considered from the architecture and API design stage, not added as an afterthought. Cloud & Scalability: I can work across application and infrastructure layers, from Spring Boot services all the way to AWS deployment and scaling. Business-Focused: My goal isn't just to deliver code. It's to understand what you're trying to achieve and build a solution that provides real business value. 🔧 Looking for help with Java, Spring Boot, AWS, React or AI? Whether you're building a new application, modernizing a legacy Java system, securing APIs, migrating to the cloud, improving performance, or adding AI capabilities to an existing product, I'd be happy to discuss your requirements. Let's build something reliable, secure, scalable, and future-ready.
