Dittmer Sensible Leadership Coaching, LLC henry@sensible-leadership.com +1 (303) 810-4905 BEN TOMLIN (btomlin@uw.edu) I’m pleased to share my wholehearted recommendation of Paul Stewart. I originally worked with Paul at the intersection of technology and learning innovation. At a time when digital collaboration was just beginning to take shape, Paul helped us envision and execute an ambitious solution that merged content, community, and utility in a single, intuitive system. What impressed me most was Paul’s ability to deeply understand the people at the center of the work. He actively engaged all stakeholders—whether strategic leaders or frontline users—to co-design meaningful outcomes. He guided us through choices with clarity, balancing bold innovation with practical delivery. The result was something visionary, built well before many of today’s mainstream tools emerged. And yet Paul’s strength wasn’t just technical—it was his commitment to solving real- world problems and advancing the mission through design and engineering. Even as our careers progressed, I’ve remained inspired by Paul’s foundational approach: engage thoughtfully, build iteratively, and measure success by impact. The principles I observed in those early years have clearly endured in the way he continues to lead teams and deliver change across sectors. I hold Paul in the highest regard as an innovator, mentor, and leader. Any forward-thinking organization would benefit greatly from his presence. Warmly, Ben Tomlin Senior Director, Communications btomlin@uw.edu To whom it may concern, It’s my pleasure to offer this recommendation for Paul Stewart, whom I’ve had the opportunity to work with closely over the past several years on the development and continuous evolution of a specialized digital platform. From the beginning, Paul brought more than just technical expertise—he approached the work as a strategic partner. He took time to understand the needs and dynamics of our clients and end users, and he translated that understanding into a platform that was not only robust and secure, but remarkably intuitive. Paul was instrumental in shaping a product that handles complex workflows and permissions without ever losing sight of user experience. One of the things I appreciate most about Paul is his ability to manage complexity with calm clarity. He leads with thoughtfulness, listens intently, and never loses sight of what success looks like for the people on the other side of the screen. Under his leadership, projects were delivered on time and under budget, and always with scalability and adaptability in mind. Beyond the technical scope, Paul has been a valued thought partner as our work has grown. Whether navigating tight timelines or evaluating new opportunities, I’ve consistently relied on his clear thinking, grounded perspective, and collaborative spirit.

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.

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.

Chris Thorne

Hi, I'm Chris, a software engineer based in London working primarily with web technologies. As an experienced professional with a computer science background, I can help you learn or improve in many areas of software development and am happy to tailor sessions to your needs. In terms of topics we can dive really deep into, my professional toolset nowadays is primarily: - Python - Django - JavaScript - React - PostgreSQL - Docker - AWS (qualified Solutions Architect) - Azure I also conduct technical interviews and would be happy to work through some interview-style questions if that's something you need to prepare for. I have around 10 years of professional experience but my interest in programming goes back 17 years when I first started learning Lua scripting as a hobby with a mentor of my own. I strongly believe that anyone can learn to code if they set their mind to it with access to the right support for the questions we all have when learning something new. In the past, I've also done some open-source work and notably managed to contribute a bug fix to CPython in one of the language codec modules. This is something I'd love to do more of or guide others in doing. If you're looking for a patient mentor with a wide range of experience who can break things down into plain English terms, don't hesitate to get in touch! ---- **Links:** - LinkedIn: https://www.linkedin.com/in/libcthorne/ - GitHub: https://github.com/libcthorne/
