I help teams turn AI ideas into working, evaluated, product-ready workflows. If you need an LLM app, RAG workflow, agentic prototype, AI product strategy, or a practical build/no-build recommendation, I can help you move from "we should use AI" to a working plan, prototype, and next decision. I bring an uncommon mix of product leadership, UX judgment, and hands-on build fluency: - VP Product Manager, AI in MLIO at JPMorgan Chase - Former VP User Experience, AI across regulated banking workflows - Former Microsoft AI product designer during the Microsoft/OpenAI partnership era - Microsoft Global Hackathon winner - 60 Upwork projects, $200K+ earned, Expert-Vetted - Portfolio across enterprise AI, healthcare AI, financial services, marketplaces, SaaS, and product systems What I can help with: - LLM product strategy and opportunity assessment - RAG workflow design and prototype planning - Agentic workflow design with human-in-control guardrails - AI evaluation plans, success criteria, and readiness checklists - OpenAI / Anthropic / LangChain-style prototype direction - Product UX for AI assistants, copilots, dashboards, and internal tools - Executive-ready AI roadmap, risk, and implementation recommendations Typical deliverables: - AI workflow audit - Use-case prioritization matrix - LLM/RAG architecture sketch - Prototype scope and build plan - Prompt/system design recommendations - Evaluation and quality checklist - Product requirements and implementation roadmap - Working MVP or prototype when the scope is clear I am especially useful when a team has a real business workflow, messy requirements, security or governance concerns, and needs someone who can bridge product, design, engineering, AI capability, and executive decision-making. Best fit projects: - AI prototype or MVP for a defined workflow - RAG or LLM feature inside an existing product - Agentic workflow planning before build - AI readiness review for a product, team, or operation - Product strategy for AI-enabled SaaS, CRM, internal tools, or service operations If you want a flashy demo with no operational thinking, I am probably not the right fit. If you want practical AI work that can survive real users, real constraints, and real decision-makers, I can help.

You hired developers to build your product, but you’re not sure if they’re really building the right thing or building it the right way. Progress seems to be slowing, things feel like they’re drifting off-track, and you’re not sure how to turn it around. Maybe your CTO has left. Maybe you've never had one. Maybe an agency built the platform and you're now left with the challenge of trying to take it forward. I'm a Fractional CTO for startups and scaling businesses that can provide the expert senior leadership without the full-time commitment. 𝐖𝐡𝐚𝐭 𝐈 𝐃𝐨 I step into your business and take ownership of the technology side. I work directly with founders, developers and agencies — joining standups, reviewing code and architecture, resolving technical decisions and keeping delivery on track. Whether you're replacing a CTO, struggling with an outsourced team, rescuing a project that's gone off track, or turning a prototype into production software, I've probably dealt with something similar before. I've spent more than two decades building software, so when a developer tells me something will take three months, the architecture needs rebuilding, or a problem "can't be fixed", I can evaluate that myself. 𝐇𝐨𝐰 𝐈 𝐖𝐨𝐫𝐤 I don't want to be the CTO you speak to once a month. I embed with your team and stay close to what's actually being built. That means standups, Slack or Teams, architecture decisions, code reviews and regular releases. I favour short development cycles, clear priorities and visible progress. If the team is slowing down, I'll find out why. If it's a process problem, I'll fix it. If it's technical, I'll help solve it. If it's a capability problem, I'll tell you. You shouldn't have to wait three months to discover that a project is three months behind. 𝐄𝐱𝐩𝐞𝐫𝐢𝐞𝐧𝐜𝐞 I've worked across Banking, Travel, SaaS, healthcare, AI, mobile applications, data platforms and enterprise software. I'm hands-on technically, with experience across React, Angular, Node.js, TypeScript, AWS, GCP, Azure, databases, AI/LLMs, DevOps and security, but I'm stack-agnostic. Technology should fit your business. 𝐖𝐡𝐚𝐭 𝐈 𝐃𝐨𝐧'𝐭 𝐃𝐨 I'm not an agency and I'm not tied to a development shop. If I recommend someone, it's because I think they're right for your business. I'm not simply a project manager either. A PM can tell you a developer says the project is 80% complete. I can look at the code, architecture and infrastructure and tell you whether that's actually true. And while I can get hands-on when needed, you're hiring me to make sure the whole technology function works. 𝐅𝐀𝐐𝐬 𝐐: We got burned by a previous agency. How is this different? 𝐀: I'm on your side making sure whoever builds your software does it properly. I review the code, challenge estimates and technical decisions, identify scope creep and catch problems early. If something is going wrong, you should know before the budget is spent. 𝐐: We already have developers. Why do we need a Fractional CTO? 𝐀: Developers build the product. Someone still needs to make sure the architecture is right, technical risks are understood, quality is maintained and the team is delivering effectively. Without senior technical leadership representing the business, those decisions often end up being made by the developer or agency you're paying to do the work. 𝐐: Can you audit what my current developers or agency have built? 𝐀: Yes. This is often where I start. I'll review the code, architecture, infrastructure, security and development process and give you a clear picture of what you actually have, what's good, what's concerning, what needs fixing now and what can safely wait. 𝐐: Our CTO, developer or agency has left. Can you take over? 𝐀: Yes. I'll establish what exists, make sure your company controls its code, hosting, databases, domains and third-party services, identify immediate risks and put a practical plan in place. If you need new developers, I can help recruit and assess them too. 𝐐: What if my developers or agency are underperforming? 𝐀: I'll work out why. Sometimes it's process, sometimes poor requirements, sometimes technical problems, and sometimes it's capability. I'll fix what can be fixed and if the team needs to change, I'll tell you. If any of this sounds familiar, send me a message. Tell me what you're building, who's building it and what's going wrong. I'll tell you whether I can help and what I'd do next.
