Summary
🤩
Rockstar🎓
Top SchoolSerkan Özal is a founder and systems architect with 13 years building high-performance distributed systems, serverless observability, and big data platforms, combining hands-on JVM and low-level Java expertise with cloud-native design. He co-founded Thundra (acquired by Catchpoint), contributes to OpenTelemetry as a maintainer and approver, and is recognized as an AWS Serverless Hero—bridging product, ops, and open-source communities. His research-focused background (MSc in Big Data & Cloud Computing and ongoing PhD on indexing for Hadoop/Hive) informs practical optimizations like off-heap storage and bytecode instrumentation used in production. Notably, he has a track record of squeezing extreme performance from Java (contributions to the One Billion Row Challenge) and integrating observability agents into local AWS emulation environments like LocalStack. Based in Ankara, he blends academic rigor with startup execution and a habit of prototyping open-source ideas that later ship at scale.

OpenTelemetry auto-instrumentation and instrumentation libraries for Java
Role in this project:
Back-end Developer & Test Automation Engineer
Back-end Developer & Test Automation EngineerContributions:13 reviews, 4 PRs, 49 comments in 4 years 3 months
Contributions summary:Serkan primarily focused on instrumenting and testing AWS Lambda functions within the OpenTelemetry Java instrumentation project. Their contributions include excluding internal Lambda handlers from being traced, ensuring correct behavior for both new and legacy internal handlers. They also worked on integrating the `aws-lambda-java-serialization` library for input/output serialization and added network peer address attributes to the spans generated for okhttp-3.0 instrumentation.

1️⃣🐝🏎️ The One Billion Row Challenge -- A fun exploration of how quickly 1B rows from a text file can be aggregated with Java
Role in this project:Back-end Developer & Performance Engineer
Back-end Developer & Performance EngineerContributions:6 PRs, 25 comments in 1 month
Contributions summary:The user, serkan-ozal, primarily focused on optimizing the performance of a Java-based application designed to aggregate data from a large text file. Their contributions include implementing the initial solution and iteratively refining it through various performance improvements. These refinements involved code optimization, using vectorization techniques, and optimizing memory usage by utilizing shared memory arenas and regions. They also made several improvements to the build and deployment process.
