COBOL tutor
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. 🐧🍏

“I had a fantastic session with Erum focused on understanding the internals of the Spark UI. She explained complex concepts like stages, tasks, and shuffles in a very clear and visual manner. What really stood out was how she connected the theory with real Spark execution graphs and showed me how to interpret performance metrics effectively. Erum also guided me through practical optimization techniques—like how to reduce shuffle overhead, how Spark breaks jobs into stages, and how to use partitioning intelligently. Highly recommended for anyone needing deep, hands-on Spark guidance“

“I've been learning with Lucas for over a month now, and I can confidently say he's both an incredible person and a top-tier DevOps instructor. From the very first session, we dove into a complex, containerized environment involving legacy on-premise integration and Lucas guided me through it with clarity and confidence. What sets him apart is not just his deep technical knowledge, but his ability to identify exactly where your understanding breaks down and fix it on the spot. He’s helped me build a solid programming foundation, structure a learning roadmap, and bridge the gap between my CISSP background and my new direction in DevSecOps. His mentorship has been instrumental in my career transition. I genuinely look forward to every session not just for the learning, but because working with Lucas is simply inspiring.“
