Micheal Edekin

I started out as a Structural Engineer, graduating from UNIBEN, finishing among the top 5 in my class, before taking a path that led me deep into the world of AI/ML Engineering. That transition wasn't linear, it was built on exposure, experimentation, failure, and a lot of learning along the way. Through it all, one thing has never changed: I'm most alive when I'm at the intersection of technology and real world problems. Growing it, evolving it, building it, scaling it. That obsession has shown up in the work, from building the first-ever AI-powered RFP at TalkDEI, to finishing in the top 5 globally at Hamoye, to consistently scoring 98/100 on technical assessments. I've also had the privilege of mentoring and teaching over 5,000 individuals across various skillsets.

Freelance D3.js Developer5.0 (1792 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. 🐧🍏
