About Ajay Kumar

Passionate Software Developer with 1.5 years of experience designing and building scalable distributed systems and microservices. I work primarily with Java, Spring Boot, and Node.js, deploying real-time, high-performance applications in AWS and Azure environments. I love solving complex backend challenges — from optimizing PostgreSQL and MongoDB queries to integrating Kafka and Redis for real-time event processing. I enjoy automating infrastructure with Terraform and Helm, and deploying resilient, containerized workloads using Docker and Kubernetes. Monitoring and reliability are just as important to me — I’ve implemented Prometheus and Grafana for real-time insights, and focus on clean, well-tested code with robust CI/CD pipelines. I’m driven by learning, collaboration, and building cloud-native systems that make a real impact. Let’s connect if you’re working on innovative ideas that need reliable, high-performance solutions!
