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 am a DevOps engineer with experience in automation, networking, and server management. My interest lies not just in solving problems but in using industry best practices to deliver quality code. I believe that all problems have solutions, but not all solutions are best for the problem. Therefore, in finding the solution best suited for the problem, input from others is needed.
With over 25 years in the software industry, I bring a robust mix of hands-on engineering and management expertise. Currently, I lead the teams for Gemini Code Assist at Google, where we develop and scale backend systems and extensions for both VSCode and IntelliJ to deliver high-performance code assistance. As a startup founder and an innovator, I enjoy wearing multiple hats, diving into new technologies, and taking prototypes from rapid development to production-scale systems. Proficient in over 15 programming languages, I primarily focus on JavaScript, TypeScript, Node.js, Electron, and Web technologies, with occasional use of Python. My approach is rooted in scalable solutions and inspiring teams to deliver impactful results.
I've been making websites, apps, games, art, for 14 years. I've taught in-person courses about multiplayer game development, and helped many mentees learn to code and use technologies from 0. I'm patient, seek to understand what's blocking you, and genuinely want to help you grow. Let's grow and enjoy this blip of time together! :)

Hi, I'm Pablo, an Argentinian full-stack developer and team leader specializing in Node/JS/TS projects. I've built production-grade applications with React, Vue, and Svelte while managing medium to large teams. I turn complex requirements into elegant solutions—and occasionally, I turn mate into code that actually works.
I’m a Staff-level Software Engineer and Engineering Manager with over a decade of experience building and leading high-performing teams across SaaS, integrations, and cloud platforms. I specialize in JavaScript, Node.js, React, AWS, and full-stack architecture, and I’ve led large-scale migrations, AI-driven initiatives, and developer enablement programs. I currently manage engineers at Help Scout, where I oversee modernization of our settings architecture, integrations with platforms like Stripe, HubSpot, and Mailchimp, and AI-assisted developer workflows. Prior to this, I managed teams at 2U (EdTech) and Trove (Recommerce), driving platform scalability and developer growth. I can help you: Architect scalable React/Node applications or migrate legacy codebases. Design APIs, third-party integrations, or serverless systems in AWS. Improve team processes, code review culture, and developer productivity. Prepare for technical interviews or engineering manager roles. Whether you’re a developer looking for mentorship, or a founder seeking technical direction, I’ll meet you where you are and help you reach the next level in your craft or product.
