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.
I have been programming on various web and cross platform stacks. I love making things and helping people build things. If you need help with your project, fixing bugs, refactoring your codebase, guidance on how to give your web app a better architectural foundation, I'm your guy.
Hi! My name is Ethar, though you'll get away with pronouncing it "Ether".
"I love coding!" and despite that intro, I don't like sounding like Donald Trump. Not that you could ever confuse us two really :) I've been a full stack guy for over 20 years and these days, churn out JS, Node, C#, both SQL & NoSql and run on AWS, including developing IoT platforms and Alexa skills.
As well as coding help, I also encourage developers and architects to look at problems differently. Committing to effective, clean, value driven solutions is crucial and my experience both in code and business provides a unique slant on why code is written in the first place. I also regularly recruit, so understand the needs of folk trying to break into the industry.
Despite over 22 commercial years in the IT industry, holding very senior roles, and running companies and organisations, I still prefer coding. I've spent a lot of time doing complex computing tasks and building circuits, and work across IoT, AI/Machine Learning, High performing computing and use Lean-EA and Lean Startup to help enterprises and startups alike work more effectively. Many of my calls end in YAGNI (You Ain't Gonna Need It), which saves on unnecessary costs elsewhere.
Ethics? Plenty. Probably to my own detriment.
Projects: Contributed to OSS including JabaJS and a local community tech calendar Alexa Skill OSS project called "WhatGeeks" (accepting PRs if you're interested).
Software Engineer specializing in **cloud infrastructure**, **scalable data management**, and **iOS development**—led several cost-savings and security projects, built privacy-first apps with **1M+ users**, and mentored engineers to success
Long time coding mentor - I've helped dozens of high-school and college kids for help with their coding assignments. We've all been there!
I'm a full-stack developer with 10+ years of experience, and I co-founded IT4Best, a Romania-based consultancy that helps startups and scaleups build robust MVPs and production-ready web apps.
Prior to launching IT4Best, I worked at Web3Box, where I contributed to platforms like Motobucks (https://www.motobucks.com/), RingMyStylist (https://www.ringmystylist.com/), and initial versions of tools for Quotible (https://www.quotible.com), a US-based automotive tech company.
After starting IT4Best, Quotible chose to continue working with me directly. Since then, we’ve built and maintained:
🔹 Lead Response Tool – Interactive quoting platform for dealerships (Laravel + Angular) https://www.quotible.com/lead-response
🔹 Instant Quote Widget – Widget for VDP/SRP quote generation (Laravel + Vue)
🔹 Chrome Extension – One-click lead import from CRMs (JavaScript, Manifest v3)
🔹 VINDNA Widget – VIN-based pricing & trust display (Laravel + React) https://www.quotible.com/vindna
🔹 Interactive Window Stickers – QR-based mobile vehicle info (Laravel + React) https://www.quotible.com/interactive-window-stickers
Through IT4Best, I’ve also worked on:
🔹 A large-scale travel booking platform (legacy PHP + MySQL)
🔹 A last-mile logistics platform used by global enterprise clients (AngularJS/Angular 19 + Node.js + MongoDB)
With 7 years of experience as a Software Engineer, I have a proven track record of developing efficient web applications, implementing software solutions, and leading juniors in projects. My technical skills include Java, Spring Boot, MERN, and AWS. One of my biggest achievements was the development of an API rate limiter that reduced the API load, leading to significant improvement.
I love to solve issues and debug problems that might arise into smaller solutions that make it well clear and more meaningful for anyone. I have vast knowledge with over 6 years of experience in programming with different technologies
