Full Stack Developer (Node.js & JavaScript)

Bucharest (+03:00 DST)
Romanian, English
Hi! My name is Ionică Bizău. If you're having problems pronouncing it, you can simply call me Johnny (that's how "Ionică" is translated in English). I work as full stack developer since 2012, with Node.js & JavaScript. Before that, I was creating WordPress sites and HTML/CSS apps. Currently I'm doing the best in Node.js (including command line tools), JavaScript, SVG (d3, svg.js). ♦ Node.js: 3 years of experience, +250 packages published on NPM ♦ JavaScript: 4 years of experience, lots of libraries you can download freely (https://goo.gl/ewoQsK) ♦ English good enough to talk with everybody and understand each other ♦ GitHub Enthusiast (follow me: https://github.com/IonicaBizau) ♦ Git & GitHub power user ♦ Comfortable with MongoDB (especially, the native driver for Node.js) ♦ I will not charge you if I can't fix your issue. Why you can trust me: ★ I am vegetarian. I have never eaten meat in my life. ★ I have never drank alcohol, beer and coffee in my life. ★ I work 6 days, and I rest on the 7th day. That's why I am *not* available on Saturdays. ★ I sleep from ~10PM to ~7:30AM :-) ★ I am a piano player. ★ I use Linux and VIM

Do you want to enter in the Git(Hub) world? I'd love to make the process simpler. Git can be difficult to learn, but with a bit of help, that can be a smooth experience. I can provide introduction in Git & GitHub: - Setting up the account (authentication, configuration etc). - Basic Git commands - Connecting Git with GitHub - Branches, merging and pull requests Also I'm open for Git questions.

Tony Elam Oct 04, 2016

Ionica is a pleasure to work with. I have a CS degree from Princeton University and have managed product and tech teams at multiple startups. He is very strong with JavaScript. I had one big issue, and a half-dozen smaller new features that I wanted. He just cranked through everything, fast. I liked the quick feedback and iteration. He understood my issues quickly, and was responsive to my feedback. It felt like true collaboration. Perhaps the best anecdote is the last 8 minutes. I had to run to a meeting, but I really wanted to complete a graphical query. I had 3 subparts to my idea, and he managed to write the whole thing before I had to hop off the session. I would highly recommend him, especially if you want to fix your code or help write new features.
Mike Weiksner Sep 30, 2016

Outstanding mentor. His exceptional proficiency in Node.js is abundantly apparent. Helps resolve your issue, explains why the issues were occurring, and even provides a host of reference sources to go beef your understanding even further. His accent was just a touch difficult to understand for the first few moments, but by the end of your session you'll be able to fully and easily absorb all of the knowledge this man will lay down. Also, after the session he was super easy to get in touch with via chat to help instantly debug a smaller later issue that arose. Will use again. Worth every cent. Highly recommend!

Simply AMAZING! Every single time. I am always left overjoyed after I finish a session with Johnny B. He spends all the time needed to help me fix my issues and is always there as a helping hand :D Super fast in debugging, working on features, and just coding in Javascript in general. I could not ask for a better code mentor and words cannot describe my happiness! Seriously. I love working together with Johnny B & he is really nice, patient, and kind. He is also really funny and smart <3 The best qualities of a person in my opinion :) Hehe. Keep doing what you are doing Johnny B, you make me really happy!!! I appreciate you very much and glad I found you because I know I would be super lost without ya ;) Thanks again <3 <3 <3
Nuvi Dec 24, 2015

I have so much fun coding and learning with Johnny B every session :D He is the ultimate bug killer and extremely fast at figuring out where the problem lies. I don't go to anyone else for help because we have been working really closely together on my app & he already knows where all the files are by memory! He is really dependable and reliable, which is why I can always count on him for help when I need it. This is the best code mentor you will find, especially for all Javascript needs :) ~ A true mad scientist with a sweet heart <3 Thank you for everything Johnny B. I appreciate you so much!!!

I love ending my nights before I go to bed by coding together with Johnny B and filling my brain with the bountiful amounts of knowledge that Johnny B supplies me. My eyes are always in for a show with his magical programming capabilities that I get to witness :D He's truly an amazing human being. Really glad I found him and I am so overjoyed with every session we have together.
Nuvi Dec 22, 2015

Johnny B is my favorite person to be mentored by and code with on Codementor!!! He is absolutely amazing at the craft of programming. He is insanely fast at figuring out the issue associated with the bug problems and tasks I have. Johnny is always there for me when I need help and assists me with whatever he can. I really love our sessions together because I learn so much from him rather than if I tried it by myself. Whenever I have a question about something, he presents me with simplified examples to understand the foundation which is really great. Sometimes he plays piano for me on pause breaks and shows me all his new awesome modules on Github. I am always so impressed by his work and passion! Also, he has some really cool chemistry experiments he does on Youtube as a side hobby. How cool is that? He has many amazing talents! Love this guy <3

Sessions with Johnny make me so happy and every time we finish, I am left overjoyed with happiness! He not only helped solve my issue, but he taught me more than I asked for and he shows me really amazing software related things like cool packages he made or VIM video to ASCII Art players, etc :) He is really generous in sharing his knowledge with me to help me learn and to become a better coder, plus he is really patient and kind. I really like his voice too, you can hear the sweetness :) If I can be as half as good as him in coding someday, I will be content. Thank you for everything, Johnny B -- you're the best person/mentor ever <3
Nuvi Dec 17, 2015

OH MY GOODNESS!!! Words cannot express my happiness right now :D I just learned how internet famous Johnny B is and I am really impressed & honored that he helps me <3 :) He has these amazing projects that he does for fun that are very innovative & useful to other users of all ages. I love learning more and more about him because he is such a cool and amazing person. I just love our coding sessions together because I really am learning so much than from when I first started since I am relatively new to programming still. I don't turn to anyone else for help in my Javascript needs. Johnny B is hands down the smartest, nicest, and best mentor ever.

Johnny B makes me want to become a better coder. Just from doing sessions with him, I learn so much from watching his lightning fast abilities in using VIM & Javascript. He actually got me to use VIM as well and I felt like a pro :D After he codes something, he explains the concept to me and makes sure I understand the foundation, which is a really great mentor quality! :) He is really patient if I don't know something about working with the code and we figure it out together as a team <3 I love doing coding sessions with him. Best mentor ever, right here.

Excellent mentor... Resolved a Javascript problem that I have been struggling with for some time... within a 30 minute session! I will be doing many more sessions.
Jim Maybee Dec 10, 2015

I am the 100th rating of Johnny B! Yay!!! So basically, Johnny B = happiness. Johnny B is an extremely capable and passionate programmer that picks up things quickly. He is so quick with his thinking and lighting fast fingers with the keyboard, I am always left amazed at his coding abilities. He has tremendously helped me improve my app and cleaned up the code for faster performance. After he codes something, he makes sure to test that it works and then teaches me why he did it. I would be lost without Johnny B, as mentioned multiple times -- because I mean it! He has a dedication to internalize the concepts and make sure I understand them. He brings a level of enthusiasm and commitment to his mentees that keeps them wanting his help forever :) He is always dependable and there for me when I need him, which is the best kind of mentor anyone can have <3 Follow him on Github! He has a lot of great examples on there and is an inspiration to create side projects for improving coding skills. He is a really cool guy also!!! He plays the piano really well and likes to play around with chemicals/fire, which is awesome :D
Nuvi Dec 10, 2015

Ionica did a great job once again fixing some D3 and CSS issues I had.
Taj Carson Dec 09, 2015

He really knows how to see problems and is able to transfer that knowledge as he help you to get it worked out!
Amy McKnight Dec 09, 2015

Johnny B truly cares about his mentees. He inspires you to want to be a better coder and explains everything he is doing. Johnny B is really dependable and reliable, he is always there when I need him and goes the extra mile to help me! He is also so patient and has such a great attitude. Can't say enough good things about him :)
Nuvi Dec 09, 2015

Taj Carson Dec 05, 2015

Ionica is very helpful and can figure out things very quickly, even if it's a new problem or something he's never done before.
Diego Zimet Dec 04, 2015

I super-love Ionica!! So far we have been working on GitHub and Node.JS together. I am a super-slow learner, but Ionica has so much patience with me and let's me mess up all sorts of things on my own computer! It's wonderful! Although we are at the beginning stages of our work together, we have accomplished a lot in such a short period of time and I'm starting to become more autonomous with my programming work, thanks in no small part to Ionica! I will write another review in the future to let you all know if the work continues to be awesome!! =D
Todd Squitieri Dec 04, 2015

One of the best online, and actually getting better and better. An enlightened programmer truly
Arjun Dec 02, 2015

Johnny B is the ultimate exterminator/mad scientist/detective for helping me with my app :) He has been working closely with me for the past weeks and we have a great growing Mentor-Mentee bond now. I am always excited to come home and learn coding from Johnny. He makes life so much easier :D I am so grateful that I found him. He is so fast! Anything you want done, Johnny can and will do it. He puts in a lot of effort to help out and improve the production of the code/app. He has a great heart. Bless his soul <3
Nuvi Dec 02, 2015

I always have a great experience with Johnny B! He truly loves to help people and guide them in the right direction to understanding why he does certain things for debugging and coding. I have learned so much from him compared to if I tried to learn it all myself. I would be lost without Johnny B, seriously!!! He is such a calm, sweet, and smart person which is why he is my favorite mentor on Codementor and I always turn to him for any help. I am always so amazed by all his side projects he does online -- he is a Github power user/rock star & always contributing to the community. Gotta love it. Keep it up mad scientist! :) <3
Nuvi Dec 01, 2015

Very helpful, went above and beyond to help fix my issue in Git as well as issues around final deployment on Heroku. App is now up and running!

Derrick Nov 28, 2015

No need to go anywhere else....on the summit of codementor
Arjun Nov 28, 2015

I've been coding with Johnny B a lot lately and he has really become my favorite person ever :D He is very knowledgeable in many areas and subjects about Javascript/HTML/CSS, Git/Github, JS libraries and VIM. He certainty is a jack of all trades when it comes to being an all star coding ninja & 'mad scientist' with his logic. I really love the way things are explained/taught to me through coding with Johnny. It was in a fun and engaging way & he plays the piano like a PRO! :D He is so kind and patient also, especially with teaching me VIM. I will now have VIM dreams ('black magic') :P
Nuvi Nov 26, 2015

Helped me one more time to fix some critical bugs.I am Happy :)
metalmonkey Nov 25, 2015

I think I found the coolest guy on the Internet :) Johnny is lightning fast at figuring out the solution to my bugs and also makes sure I understand what is going on. He played piano for me during our session after he fixes the bug and lets me test it out. *^_^* How awesome is that?! The best of the best on Codementor, seriously. I wouldn't go to anyone else!
Nuvi Nov 25, 2015

This session was very helpful and i, definitely, recommend this mentor. He has a lot of patience :)
Mirela Chiriac Nov 25, 2015

Where would I be without Johnny B? I would seriously be lost. He is a God send :) I admire him and his skills so much. He is the best mentor ever. He has the willingness to share his skills, knowledge, and expertise with me and taught me about VIM & debugging skills -- plus he is so FAST! He is like a "mad scientist" with his problem solving skills also. He is always so positive and never exhibits frustration when tackling tricky tasks. He provides a lot of guidance to me and motivates me to be a good coder like him someday :D Johnny B is amazing <3
