Hey there! I've been creating applications for 20+ years, and I love teaching. Your skill level is not important to me. You're a beginner, intermediate or expert developer. No problem. We all are junior developers for a lifetime, always learning. I can teach you how to pick up a new skill, or upgrade your existing skills or update you on the latest technologies. I would be delighted to mentor you also on how to develop yourself and your career, or the books you should read, the courses you should take, etc. If you're trying to create a product for your company or your startup, I can guide you on how to make it a reality. Which technologies you need, how to learn them, how to apply them. You'll be building your products or MVP in no time. I'm a scalability and web apps expert.

Test-driven, ux-focused product manager and entrepreneur who helps startups create lovable apps. Oh, and I only use my powers for good.

I spend my time working with startups as passionate as I am about building interesting products. I help distill a vision, wrap it in a memorable user experience, get it to market, and learn from it. 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?

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

Note: English is my first language; some people have indicated that this is of importance to them when choosing a mentor, which is why I'm mentioning it here. "TEACH A MAN TO FISH AND YOU'LL FEED HIM FOR A LIFETIME" If you're just looking for someone to debug your code for you, 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. My main 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. 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. 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 will pause the clock if/when I need to look anything up- you shouldn't have to pay for my needing to refresh my memory on anything. 3. I won't drag things out if I can help it. If I can help you in under 15 minutes, I will. 4. If for some reason I'm not able to find a way to help, 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.

Freelance developer with expertise in PHP / Laravel, JS / jQuery and Java.

NYC based developer with 8+ years of experience, mainly with Java, PHP, Javascript and Python. When I am not freelancing I like to help developers on CodeMentor make their projects a success or to help them through the learning process. Mentoring: I like to tailor my mentoring to the particular client. If you are a student learning programming for the first time, I will take you step by step so that you are the one solving problems as we go, with a little help from me. Or perhaps you are working on your own project and need results fast, in which case I can provide solutions and tradeoffs between them so you can learn and make an informed choice. My background: I come from 5 years experience in backend Java at a Fortune 100 company. After leaving that company, I have spent the past two years working with PHP, JS, CSS, HTML5, and Python to build web sites and apps for small companies. I use frameworks such as jQuery, Laravel and Backbone. My primary development environment is PhpStorm on Mac along with Sublime, with dev and production deployments on Ubuntu servers. I hope to be able to help you out!
