Top Senior User Developers - Dec 2017

Full-Stack CEO, Lean Startup Consultant, Super Genius, Force of Nature

A leader. A brother. (Possibly) Your secret lover. Also referred to as “Who was *that*?” or “What just happened here?”, Justice Gray is what would happen if a professional wrestler and a computer scientist had a baby, that baby married a hurricane and they had a child named Justice. He is passionate about Lean Startup principles and ideals, and Agile like a vast, predatory bird. Most importantly, he is a builder who loves to build: building applications, building teams, building businesses and building dreams. When he's not saving the world one company at a time, he can be found espousing his thoughts either on LinkedIn or at whoisjusticegray.com. Note: If you are looking for a much less prohibitively expensive - but possibly more talented and equally handsome - resource to singlehandedly rescue your company through charm and brilliance, Vancouver's Kevin Dhami (https://www.linkedin.com/in/kevindhami) comes highly recommended from yours truly. Look at that; even just *reading this summary alone* has saved you time and money!

Coding can be an art!

I'm a full-stack developer with 15+ years of experience in web application development and code mentoring. Are you stuck? Let me help!

Experienced full-stack developer. I see code as an art form.

"Whoever travels without a guide needs 200 years for a two-day journey." Whether you're just starting out on the journey to becoming a great coder, or whether you're somewhere in the middle and you just got stuck, don't let it hold you back longer than necessary. I have over 8 years of experience with multiple software stacks. I started on Java with Spring Framework, then switched to Ruby on Rails. These days I work mostly with Node.js and CoffeeScript. I've worked with 4-person startups, billion dollar companies and everything in between. My goal is to get your issue resolved as quickly as possible, and give you all the tools and knowledge necessary to *understand* why you had this issue, and how to prevent it going forward.

CTO at Draft AI | #1 CodeMentor for Python, JS, Node, React for now - still working on the others ;)

AngularJS, JavaScript, HTML and CSS expert. Full time web developer.

Up-to-date with the latest trends and technologies. I have over 6 years experience developing data driven web applications and websites. Currently, I work as a full-time Web Developer for Source Insurance Ltd, developing modern web based applications with AngularJS and C# to improve products and services for their customers. I believe in writing clean, semantic code and always sticking to the KISS principle!

Australian full-stack developer/designer with almost 20 years of experience: Learn: advanced JavaScript/Typescript, HTML/CSS, software architecture/design, functional/reactive programming with streams, Photoshop, UI/UX design, career guidance and more.

Note: I am often in "away" mode when I am working. I work for myself though, so if you're reading this and would like a session with me, disregard my "away" status and shoot me a message anyway. I'll do my best to accommodate you. I also let my regulars add me on Skype, in order to message me more easily. We'll then tend to jump into Codementor for a session. "TEACH A PERSON TO FISH AND YOU'LL FEED THEM FOR A LIFETIME" My strength is helping you learn to code, debug, structure your application, and in general, how to be a good developer. If you want to develop the skills to build anything you can dream up- to switch easily from one language to another, to implement existing algorithms and data structures, design your own algorithms and data structures, analyse any codebase, debug any problem- I can help you learn language fundamentals, debugging skills, architectural thinking, and the mindset you'll need to develop your desired skill set. If you're looking for someone to debug your code for you, or to "just tell you what to type", I can probably help to some degree, if I've recently used the particular combination of technologies and libraries you're having trouble with, and/or if the scope of the problem is small and focused. You'll probably get more value from me by having me help you learn to debug more effectively though, using the particular bug you're having trouble with. LEARN BY DOING If you have a starting point, whether it's just an idea, or a partially-developed app, I can walk you through building it out, restructuring it (and knowing how to identify where to do so), filling in knowledge gaps that you have, and so forth. It's easier to learn when you're building a real thing, so I aim to help you fast-track that learning process. BECOME HIGHLY EMPLOYABLE I often hear developers having trouble with having to compete with many other developers and wondering if the market is too crowded, and why they have so much trouble landing the roles they want. The truth is that really good developers don't ever have trouble getting work if they want it. If you want to be the kind of developer that can pick and choose which roles you want, ask for guidance. WHY ME? I am friendly, extremely patient, and pride myself on being able to explain things in a way that you will actually understand. Too many developers take basic concepts for granted, and end up just confusing people when trying to explain an idea. I think it's important to be aware of my audience and I try to tailor my approach to the individual in question. I do both visual design (UI/UX) and full-stack development, and have spent almost my entire career glued to a screen doing some kind of software development both on and off the job. Most of my experience is with web-based application development, though I have ventured into client app development, 3D engine design, game design and so forth as well. Currently I'm working on the biggest project of my career; a self-directed endeavour in which I'm trying to redefine and merge a number of fundamental paradigms in software development, dataflow and user experience by combining concepts for which the relevant expertise is not usually found under the same roof. Codementor helps keep me independent while I do this. I know that a long session can cost you more money than you'd like, so to ease your mind, my personal policy for mentoring is: 1. I'll only start the clock once I know that I can help you. 2. I won't drag things out if I can help it. Time is money. If I can help you quickly, I will. 3. If you're unsatisfied with my service, or I wasn't satisfied with the value I provided, I'll issue an immediate refund on the time logged. Bottom line is I'm not happy if you're not happy. If you don't think my assistance was worth a five star rating, I haven't done my job and you won't be charged. Note: English is my first and only language; I am Australian, though my accent is fairly neutral. Some people have indicated that the language barrier with non-native English speakers can be an important consideration for them when choosing a mentor, which is why I'm mentioning it here.

startup advisor, speaker, CEO. More than mildly obsessed in seeing founders succeed. I only use my powers for good.

Every day, I get to work with startup founders as passionate as I am about building great products. I'm the CEO of Mindbox Studios, a custom software development shop and innovation lab, where I work with a diverse group of creatives, strategists, investors, and engineers to help founders take their ideas to market. I am a big fan of rapid iteration and hypothesis testing, and bring an intense desire for lovable interactions and a laser-sharp focus on measurement to every project. I believe creating a great product means embracing failure. If one has never had a bad idea, how would she know if she had a good one?
