Top Senior Concurrency Developers - Nov 2017

Full Stack Developer

I design, build and scale high-performance web applications using an open-source technology stack. I work primarily with Django and Python to create scaleable cloud backends and React.js to build beautiful and crisp single-page Javascript applications for web and mobile.

Started programming at age 12 in 1988 on a Commodore VIC-20. Worked in multiple industries developing various types of software. Decades of experience.

Mobile Dude

Bonjour! I am Bohdan, mobile apps developer. Need help or advice? Urgent homework or deadline got too close? I am the guy you was looking for.

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

First of all, I go by KZ so you don't have to hurt your tongue trying to pronounce my name :) I mostly work on the JVM in Java and Android (and recently Kotlin which is by far my favorite!!!) I have a strong theoretical background as well as almost a decade of practical experience. I love learning as much about a topic as I can so I consider myself an expert in the areas I invest my time into (JVM memory model, concurrency, object layouts, etc.). I practice Test Driven Development wherever practical and am a disciplined debugger (I once spent a better part of the day tracking down what turned out to be an equals/hashCode mismatch in legacy code). I'm also extremely passionate about language design and attempt to evangelize new constructs to whomever will listen :) I look forward to working with you.

Full Stack Java/JavaScript/Scala Engineer

I am a Software Engineer with a decade of work experience in different areas. I like to make things work and organized, weather it's building pipeline for my code to go directly in production with Docker containers and Orchestration technology. Making sure I've found problems before users touch my code. The best compliment that I've got is by people who left to maintain my code - "It's by the book".

Experienced Software Developer, Author of C++ Concurrency in Action

My primary area of expertise is in the development of multi-threaded applications and libraries in C++. I am the author of C++ Concurrency in Action, published by Manning. I am an application and library developer, with extensive experience developing for Windows and Unix, especially database applications and client-server applications. I have an excellent in-depth knowledge of C++, along with a working knowledge of many other languages, such as Delphi, Java and C#. I have developed numerous GUI applications for Windows, and have a keen interest in developing easy-to-use interfaces. Specialities: C++ programming, concurrency, GUI design, database design

Functional Programming expert (Scala, Haskell, Elm)

I'm co-author of the book Functional Programming in Scala and have been doing FP professionally for many years. I look forward to helping teach and mentor other interested functional programmers!

Docker, DevOps & AWS Cloud Architect, Author & Certified AWS DevOps Engineer Professional.

I am an evangelist and thought leader in the AWS Cloud, Docker and DevOps space. In addition to being a Cloud Architect, I also impart training in AWS, Docker and other DevOps related technologies. My core specialty is building scripted, version-able, repeatable, auto-scaling, load-balanced and self-healing infrastructures. I also work in server-less architectures using AWS Lambda service and Internet of Things (IOT). I currently hold multiple AWS certifications including the DevOps Engineer - Professional. My strengths include: - Deep AWS, Docker & DevOps expertise and experience - Mission critical enterprise scale experience - Server side scripting - Full stack experience - Technical writing - Technology training

Patient teaching ... (Program/System)Design help ... Implementation help.

Full stack development, python/tornado/postgres/html/css/JS, C++ veteran, rendering. I can help with any of the above, using or creating algorithms and data structures to solve interesting problems.

Engineer, Entrepreneur and Thinker of solutions that work

Get support from one of the first professional full-time Clojure experts in the world – possibly THE first. I will help you to progress with your projects in Clojure, ClojureScript, Java, Jave EE (JEE / J2EE), JavaScript and Common Lisp. Want mentoring on machine learning and AI? Want to learn about functional programming, lazy sequences, transducers, multiversion concurrency control, fully persistent data structures, neural networks or bayes classifiers? I’ll teach you how to do this! Backend? Frontend? I’ll help you with both! Some example backend server technologies: Clojure, Java, JEE, PostgreSQL, MySQL, MSSQL, Oracle, WildFly (JBoss), Immutant, Ring, Compojure, etc. On the frontend I will support you directly in JavaScript, or do you work on your super modern single page app with ClojureScript and Om (Facebook’s React)?
