Senior🎓
Top SchoolDániel Juhász is a Java developer with nine years of experience building and maintaining backend systems for large-scale services and energy-sector platforms. He has worked on high-volume subscription and payment systems at Disney+ Hotstar and led backend and AWS migration efforts for car charging and car-sharing billing solutions. Comfortable across the full backend stack, he leverages Java, Spring, PostgreSQL, RabbitMQ and cloud tooling (AWS, Terraform) to deliver resilient microservices and CI/CD-driven deployments. Earlier in his career he managed large Exchange environments and automated operations with PowerShell, which gives him strong operational discipline and incident-handling experience. An active contributor to open-source game-engine tooling, he optimized complex lighting algorithms in a voxel engine by redesigning update flows and caching, highlighting an ability to improve performance at the algorithmic level. Based in Hungary, he combines hands-on coding with team leadership and cross-functional coordination to turn business requirements into reliable production software.

Contributions summary:Dániel focused on improving the lighting system within the voxel game engine. Their work involved rewriting light updating procedures, introducing priority queue-like containers for iterative solutions, implementing per-node MapBlock caching, and optimizing light calculations within map blocks. The changes aimed to enhance performance by skipping unnecessary light updates and improving how light is spread within the game world. This work also involved modifying liquid transformation to update lighting for the changing nodes instead of whole map blocks.
