He spends his time tackling the challenges of running Java in serverless environments. While Java is often criticized for slow cold starts and heavy memory use on cloud infrastructure, Vadym breaks down how to make it run fast. His teaching covers benchmarking AWS Lambda performance, hardware architectures, and modern tools like GraalVM and AWS SnapStart to help engineers drastically cut down on processing delays. ## Past Sessions ### World Congress 2026 Europe - Virtual Stage 路 June 30, 2026 Online - [Practical performance tuning for Serverless Java on AWS](https://www.wearedevelopers.com/events/world-congress-2026-europe-virtual-stage/sessions/1587-practical) ### World Congress 2025 路 July 9, 2025 Berlin, Germany - [High performance Serverless Java on AWS](https://www.wearedevelopers.com/videos/1555-high-performance-serverless-java-on-aws) 路 30 min 路 馃帴 Watch recording ## Videos - [High performance Serverless Java on AWS](https://www.wearedevelopers.com/videos/1555-high-performance-serverless-java-on-aws) 路 Vadym Kazulkin ## WeAreDevelopers LIVE - [High performance Serverless Java on AWS](https://www.wearedevelopers.com/videos/1205-high-performance-serverless-java-on-aws) 路 Vadym Kazulkin ## Links - [X](https://x.com/VKazulkin) - [LinkedIn](https://www.linkedin.com/in/vadymkazulkin/) - [GitHub](https://github.com/Vadym79)
