Personal Profile
NetBeans founder and initial architect who remained (after being acquired by Sun) with the project for next fifteen years in the corporate world. Then switched to slightly more academic environment by working for OracleLabs (yet still delivering production ready PostMortemDebugging into OracleDB). Just to enjoy hard working startup experience for one more time with Enso.
Passionate about leading teams into projects nobody thinks can succeed, overcoming all obstacles and bringing them into production:
- NetBeans IDE - first IDE for Java written in Java
- NetBeans Platform - the first Swing based modular application framework
- NetBeans performance - speeding NetBeans 6.1 startup by 60%, eliminating memory leaks, improving scalability
- Netbinox - changing NetBeans architecture to support OSGi by creating the fastest OSGi framework on the planet
- JDeveloper - rebasing years of development on top of NetBeans Platform to gain startup speed and share functionality
- Attempt to bring Java back to browser via my Bck2Brwsr (e.g. JVM transpiling to JavaScript) project.
- Winning Duke Choice Award for DukeScript project contributions (including Bck2Brwsr effort & co. like Kotlin API design of kt-mvvm).
- Bringing initial product aspects to a research project by designing Truffle polyglot API & co.
- Polishing GraalVM to be closer to production - AOT, PGO, JNI, tooling integrations
- Invented GraalVM Insight and used it for PostMortemDebugging in the OracleDB
- turned Enso into stable, fast, robust, and rock solid, production ready live coding environment
- Realized Dual JVM mode for Java applications - starting blazingly fast (the AOT compiled code part) while still using HotSpot JVM then
Publications & Presentations
Practical API Design, Apress 2008 - the first book about API Design describing all details related to API design published way sooner than the term API was kidnapped by REST and JSON guys.
20 API Paradoxes, Walrus 2012 - shorter, more strictly organized continuation/summary of Practical API Design book.
Rich Client Programming: Plugging into the NetBean Platform - contributed few philosophical chapters to book about NetBeans Platform.
Regular speaker at JavaOne and other conferences (GeeCON, GeekOut, JDD, CurryOn, JavaDays).
Teaching at Charles University's MatFyz for few years (during OracleLabs employment). My Practical Dynamic Compilation course attracted few interns into OracleLabs. At least two of them turned into regular employees then. See twenty hours of video (in Czech)
Theoretical Work
Typing in terms of graphs - master thesis at MatFyz describing type system similar to what later became Generics in Java. The paper is using unique, graph based terminology.
Proofs of NP-Completeness of various topics related to modularity with practical implications for anyone designing or using a module system.
Technical Skills
- Able to use debugger to gain insight into behavior of own or any foreign system
- Usually (almost) the most productive developer in any team
- Typing (without looking at keyboard) and thinking fast, yet concluding slowly/carefully
- Knowledge of classical languages (especially Java, but also C & etc.), functional languages (like Haskell) and logical languages (e.g. Prolog).
- Knowing how to implement any language and make it run fast - just like done with Enso
- Knowing a lot of about API Design and almost everything about API Design in Java
- Understanding general implications of modularity and how to organize a project in a distributed fashion.
Organizational Skills
- Designing process for API Reviews which allowed NetBeans to design APIs in a committee style and still keep consistency.
- Designing, advocating and implementing parallel integration which greatly improved productivity of NetBeans developer teams
- Enabling, promoting and advocating test driven development to increase quality of NetBeans code base
- Founded OracleLabs subsidiary in Prague
- Attracted skilled developers by talks at universities, conferences and meet-ups
- Helped to select and on board newcomers.
- Convinced whole experienced team to join OracleLabs and contribute to GraalVM vision
- Handed the responsibilities to professional manager when the team grew over fifteen.
Languages
- Czech - native
- English - fluent
- Russian - can read
- Polish - passive understanding
- German - survival level
Spare Time Activities
Skiing and snowboarding and other sports. Bck2Brwsr VM. Various open source projects (mostly hosted on GitHub, but also for example contributed to Linux kernel driver).
