About Eshwar K

Enterprise systems don’t fail because of code, they fail when they can’t scale, handle real-time transactions, or meet security and compliance standards. In banking and healthcare, performance, reliability, and data protection aren’t optional,they’re critical. I work on building systems that stay stable under pressure and are designed for real-world production environments.I’m a Senior Java Full Stack Developer with 8+ years of experience across Banking, Healthcare, Retail, and Insurance domains. I work on designing and building scalable backend services using Java, Spring Boot, and microservices, along with secure REST and GraphQL APIs using OAuth2 and JWT. On the frontend, I build responsive enterprise applications using Angular and React with TypeScript to deliver reliable user experiences.My experience also includes building event-driven systems with Kafka and messaging platforms, working with relational and NoSQL databases like Oracle, PostgreSQL, MongoDB, DynamoDB, and Redis, and deploying cloud-native applications using AWS services, Docker, and Kubernetes. I’ve worked extensively with CI/CD pipelines, automated testing, monitoring, and performance tuning to ensure systems remain reliable in production. Some of the work I’m proud of includes modernizing legacy banking platforms into cloud-native architectures, reducing batch processing time by 40% through performance tuning, improving healthcare billing workflows, and delivering scalable applications that support high-volume enterprise transactions. If you\'re hiring for enterprise Java, microservices, or cloud-based roles in Banking, Financial Services, or Healthcare, I’d be happy to connect and discuss how I can support your team.
