L.E.Santhosh Kumar

Software Engineer

I design and build web applications with a focus on modern web technologies.

With over 11 years of experience in Java and ReactJS development, I specialize in building scalable architectures, robust backend services, and dynamic front-end interfaces. I have led projects that improved system performance, security, and user engagement, delivering high-quality software across diverse domains.

Notable achievements include:

  • Developing a web-based emulator for AS400, modernizing legacy systems using ReactJS and Spring Boot.
  • Implementing Elasticsearch-powered search, increasing data retrieval speed and accuracy.
  • Designing a sports game simulation module that reduced testing time by 70%, accelerating release cycles.

I have also worked on critical security implementations like MSSQL Always On encryption and identity integration via OKTA, ensuring compliance and system resilience. My strength lies in full-stack engineering, system optimization, and driving secure, maintainable codebases.

Beyond full-stack development, I’m a passionate solo game developer, currently exploring Unreal Engine and Blender to build immersive 2D/3D game worlds, inspired by my favorite RPGs.
