At North Data GmbH, I built Java data ingestion pipelines on Google Cloud Platform to collect and refresh company registrar datasets. I processed HTML, text, and documents using JSoup, Gemini, and OCR, and built internal Java developer tools with the GitHub API.
At LemonGaming LTD, I reduced certain SQL query latencies from several seconds to single-digit milliseconds by re-engineering queries and MariaDB database structures. I also built distributed Java backend communication using Redis messaging and Protocol Buffers/JSON serialization.
At Telara Studios, I engineered a packet-based player distribution system across Java server instances using NATS.io, and designed and built a permissions system backed by MariaDB. In freelance engagements, I designed Java backend infrastructure to distribute player sessions across server instances and implemented cross-server messaging.
