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. 🐧🍏

Is your AI-powered MVP built on a fragile 'vibe-coded' foundation? Are you struggling to scale a prototype that was built with lightning speed but is now plagued by bugs, security holes, and technical debt? I transform brittle AI prototypes into robust, **production-ready applications**. As a senior AI engineer specializing in the **Node.js** and **React** ecosystem, I bridge the gap between rapid, AI-assisted development and the disciplined engineering required for scalable, secure software. But robust software is only half the battle. The other half is making it *work for your business*. I design and implement **intelligent automation workflows** that connect your apps, eliminate manual tasks, and free up your team to focus on high-impact work. Whether you need to rescue a failing project, automate a core business process, or build a scalable MVP from the ground up, I provide the expert oversight to ensure your AI initiatives deliver real, measurable value. **My Core Services:** * **🤖 AI Code Rescue & Remediation:** I conduct deep **AI code audits** to debug, refactor, and secure fragile codebases (especially those built with LangChain.js). I turn unmaintainable prototypes into stable, scalable assets ready for real users. * **⚙️ Intelligent Workflow Automation & Integration:** I design and build digital assembly lines for your business. I offer a full spectrum of automation solutions: * **Rapid Integration:** Using **Zapier, Make.com & n8n** to connect your existing tools and solve immediate process bottlenecks. * **Custom API Development:** Building custom **Node.js** APIs and webhooks to connect proprietary systems or handle complex logic that no-code tools can't. * **AI-Powered Decisions:** Infusing your workflows with intelligence using the **OpenAI API** to triage support tickets, qualify sales leads, or generate content automatically. * **🚀 Custom AI Solution Development:** I architect and build bespoke AI solutions from scratch, from **Custom GPTs** and intelligent **AI Agents** to complex RAG (Retrieval-Augmented Generation) pipelines that leverage your private data. * **👨🏫 AI Engineer & Career Mentorship:** I provide 1-on-1 coaching to help developers navigate the AI landscape, master tools like LangChain.js, and build a successful career in AI engineering and automation. **My Tech Stack:** * **Languages:** Node.js, TypeScript, JavaScript * **Frameworks:** React, Next.js, Express.js, NestJS * **AI / LLM:** LangChain.js, OpenAI API, LlamaIndex, Vector Databases (Pinecone, Qdrant) * **Automation Platforms:** Zapier, Make.com, n8n Ready to move past the prototype phase and build a real business? **Send me a message with your project details or book a session to get started.** --- ### Service Packages * **Package 1: AI Code Audit & Production-Ready Roadmap** * **Description:** Have an AI-generated MVP that feels unstable? I'll perform a comprehensive review of your codebase. You'll receive a detailed report identifying security vulnerabilities, performance bottlenecks, and a concrete, actionable roadmap to make your application **production-ready**. This is the perfect first step to de-risk your project. * **Package 2: Intelligent Automation Workflow** * **Description:** Let's put a core business process on autopilot. We'll map out a high-impact workflow and I'll build a robust automation to solve it. Ideal for **automating lead qualification**, **triaging customer support tickets**, or **streamlining content pipelines** using the best tool for the job—Zapier, Make, or custom Node.js scripts. * **Package 3: Scalable AI MVP Development** * **Description:** Need to build an MVP the *right* way? I'll architect and develop a **scalable MVP** from day one, using professional, spec-driven development practices. We'll build a strong foundation with clean, documented code and a modern stack (Node.js, React) to avoid the technical debt that plagues "vibe-coded" projects.

Self-taught full stack developer. Helped over thousands of clients to build their small to large scale websites. I love building high performance and scalable websites. Over the past few years, I have been heavily working on WordPress and Laravel. My top skills are: WordPress (oh, not to mention I used many popular plugins like: ACF, Gravity Forms, etc.), Laravel, MongoDB, MySQL, ElasticSearch, jQuery, Bootstrap, Redis, RETS integration, Plesk, WHM and many more! I occasionally do system admin tasks as I am managing plenty of servers running on CentOS. If you are lost in coding, need a hand or running out of ideas, feel free to reach out to me. I am not available for a full time hire but happy to help you with any kind of help you need with your projects.

“Olajide is very knowledgeable with computers. He helped me transfer my cryptocurrency from one platform to another… this is not that easy for most people and there’s a chance you can lose your wallet. Olajide made it look easy. I think it would’ve been done very quickly if I wasn’t slowing him down. He is very kind and patient.“
