Business Intelligence Engineer with 10+ years of Looker/LookML experience and 1 year of Tableau experience. Former data scientist, web developer, and operations analyst. I'm happy to help you with building analytics solutions, whether it's just some quick questions or a longer consulting arrangement. I have worked within FAANG teams and other big tech organizations and have a great understanding of how things *should* work when the right structures are in place. I've seen enough examples of things breaking to have a good "sixth sense" with troubleshooting and take pride in my ability to solve urgent issues.
I love to teach what I know. I think I can explain things easily with examples. I have been working as a Software Engineer for the last 5 years and have worked with some of the world's most reputed companies like **Open AI, Scale AI, Doloras Lab**, etc as a freelancer.

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.

American (native English speaker) born and raised in New York City and now living in the richest country in the world, Luxembourg! I'm a product-centric CTO, engineering leader, and software engineer with 12+ years of experience crafting world-class software. I have strong expertise in React, Node, TypeScript, Python, Go, AI/ML, Azure, and much more. I've scaled organizations responsible for defining, engineering, and operating mission-critical systems optimizing $10B+ space assets while partnering with companies like SpaceX and other space. I have a powerful track record of establishing autonomous product-minded teams, pioneering agentic development workflows, and driving measurable commercial impact. For Codementor mentees: I remember exactly what it feels like to be stuck. You are writing good code, but you aren't sure how to break through to the next level. Whether that is becoming a Senior, Staff, or Principal Engineer, or eventually a VP of Engineering or CTO. Nobody hands you a manual for that transition. I started exactly where you are. I went from building React UIs as part of a scrum team to leading large organizations engineering the systems for multi-billion dollar satellite assets. Today, as the CTO of Symphonee AI, I still code every day. I do this because you can't lead engineers if you don't understand the reality of the work. I am here to help you see the things you don't know you don't know. I want to be the mentor I wish I had. Someone to cut through the noise, show you the shortcuts I learned the hard way, and help you get to that next level faster. Whether you are feeling lost, facing a specific technical challenge, or just ready to move up, let's talk.
