Summary
👤
Senior🎓
Top SchoolJacek Ambroziak is a Principal Engineer based in Cambridge, MA with over two decades of experience designing and shipping ultra-high-performance systems in Rust, C/C++, Java and Scala. He led the original XSLTC effort at Sun Microsystems—authoring the first XSLT-to-JVM-bytecode compiler whose code ships with every Java JDK—and holds four U.S. patents in information indexing and search. At Akamai and prior companies he has built LLVM-targeted DSL compilers, real-time JSON processors, and cloud-scale full-text search for EPUB and publishing platforms, often delivering projects from research to production single-handedly. A pragmatic team leader and tinkerer, he combines deep research roots (Polish Academy of Sciences, Cornell, Sun Labs) with hands-on optimization work that produced some of the fastest XSLT/XPath/JSON processors for Java. Notably, his recent 2023 Akamai effort implemented an internal DSL compiled to LLVM for maximal log extraction performance, reflecting a rare blend of compiler theory and production systems engineering.
