Johnny B. (Ionică Bizău)

Freelance Security software Developer5.0 (1743 reviews)

Hey! I am Johnny B. 🙏 (Actually, my Romanian friends call me Ionică, which in English is basically: Johnny). ...and I 💖 emojis! I started coding around 2010, starting with simple static websites, WordPress applications, and then tried Node.js for the first name around 2012. Since then, I have been working with Node.js. I like it a lot. Currently, I do the best in: ★ Node.js 🚀 ​ ​ ☆ Command line tools ​ ​ ☆ Express.js ​ ​ ☆ Passport ​ ​ ☆ Raw/minimal code, without frameworks (e.g. simple HTTP server) ​ ​ ☆ Using npm ​ ​ ☆ Creating npm packages for Node.js (and for the front-end as well) ​ ​ ☆ Scraping the web ​ ​ ☆ Automation of repetitive tasks ​ ​ ☆ Image processing ★ JavaScript ✨ ​ ​ ☆ Creating and importing libraries ​ ​ ☆ jQuery (creating plugins, using them etc) ​ ​ ☆ Scraping ​ ​ ☆ Automation of repetitive tasks ​ ​ ☆ Publishing npm packages ​ ​ ☆ SVG (SVG.js, d3.js) ★ HTML & CSS 🎨 ​ ​ ☆ Fixing CSS quick issues ​ ​ ☆ Implementing mockups ​ ​ ☆ Making the page responsive ​ ​ ☆ SEO tips & tricks ★ Command line 💻 ​ ​ ☆ Shortcut tips ​ ​ ☆ Creating command line tools ​ ​ ☆ Using VIM & Tmux ★ Code Review 👀 ​ ​ ☆ I do code review offline, for Node.js, JavaScript, eventually CSS. ​ ​ ☆ Can be done in a live session as well. ​ ​ ☆ Security checks ​ ​ ☆ I point things that can be done in a better way ★ Using Git & GitHub/GitLab/BitBucket etc. 😸 ​ ​ ☆ Introduction to how Git works ​ ​ ☆ Using Git hosting services (e.g. GitHub, GitLab, BitBucket etc) ​ ​ ☆ Top Git commands ​ ​ ☆ Shortcuts If I can help, I will definitely do it, as long your app is not promoting things that tend to be potentially immoral. For example, I'm happy to help you build an e-shop, but I will probably not build an e-shop designed specifically for selling wine since I am against the use of alcohol for drinking. ♦ 🚀 Node.js: 9 years of experience, ~700 packages published on NPM ♦ 💛 JavaScript: 9 years of experience, lots of libraries you can download freely (https://goo.gl/ewoQsK) ♦ 🗣 Fluent in speaking English & Romanian, and comfortable in Spanish & Portuguese ♦ 😸 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 a vegetarian. I have never eaten meat. 🍍🥑🥗 ★ I have never drunk wine, beer, etc. Water is the best. 💧 ★ I work for 6 days, and I rest on the 7th day. That's why I am *not* available on Saturdays (specifically between Friday's sunset and Saturday's sunset, my location at the time—you can my timezone a little bit below). 🙏 ★ I sleep between 9:18 PM and 4:42 AM. Depending on your timezone I can wake up earlier if you book a session with me. 💤 ★ I am a musician (pianist and organist). 🎹 ★ I use VIM on macOS and Linux. 🐧🍏
