Krzysztof Zienkiewicz, Java coder and developerHire Now
Freelance Java developer in Franklin, United States

Developer with a passion for testable, performant, and clean code

I've been writing Java for almost 10 years so I've had a lot of experience with most parts of the language and frameworks. Currently my code is deployed inside the core of massive scale hadoop jobs. I specialize in writing performant and memory efficient algorithms and data structures (not the easiest thing to do on the JVM) without sacrificing the maintainability of the overall architecture. I also have a deep understanding of the Java memory model and excel at parallelizing existing sequential code. I love Test Driven Development as well as educating colleagues about new Java features (Yay, Java 8 lambdas and streams).

john o'connor, top Java developerHire Now
Freelance Java developer in Lake Elsinore, United States

Mentor and Professor for Android, Node.js, and Angular

I began programming Java in college, but really became fluent in Java when the Android platform was first announced by Google around 2008. Being a computer geek I was very interested in the mobile revolution, but I was also a Linux geek and didn't have a Mac or the desire to buy one. When Android came out, I began immediately developing for it and by late 2008 I'd already written several apps on the platform. Since then Java has been one of my main languages. I've used it to write desktop applications for the government of the United Arab Emirates, develop enterprise web applications, and even programmed a smart-card controlled Arduino robot with it.
