Eight days. One person. A fully shipped iOS app. That's not a pitch — it's what I built with SHRPR, a native iOS gamification app for critical thinking. Here's what shipped in that window: 29 SwiftUI source files, 105 structured content cases, a full design system, StoreKit 2 in-app purchases, Sign in with Apple, iPad support, a live landing page, legal pages, and an App Store submission. Traditional development cost for equivalent scope: $55,000–$130,000 (US rates). My actual cost: a Claude Pro subscription and a $99 Apple Developer account. That's not a fluke. It's the result of a specific method I call multi-agent AI orchestration — running 8 specialized AI agents simultaneously across design, development, content, QA, security, marketing, and architecture, while I direct every product decision, define acceptance criteria, validate output, and catch what the agents miss. The human isn't replaced. The human becomes a one-person executive team with a staff of specialists who never sleep. What I deliver for clients: Native iOS apps (SwiftUI, iPhone + iPad, App Store submission) Web applications (React, Node.js, PostgreSQL) MVPs and working prototypes (days to weeks, not months) Landing pages and marketing sites Content systems (structured case libraries, knowledge bases, editorial systems) Design systems (component libraries, brand guides, spacing/typography specs) Full product launches (design + dev + content + submission) My tech stack: SwiftUI, React, Node.js, PostgreSQL, Figma, StoreKit 2, Sign in with Apple, Vite, Tailwind, Lovable. I handle everything from architecture through App Store submission. What makes this different from hiring a developer: Most freelancers sell time. I sell outcomes. I'm not billing you for the hours an AI agent spent writing SwiftUI views — I'm accountable for a working, shipped product. The leverage I bring is knowing exactly what to build, making the strategic decisions that determine whether a product succeeds, and running a parallel execution system that compresses 5 months of traditional development into days of active work. To be honest about what this is and isn't: AI-assisted development works best on greenfield projects where requirements are clear. It is not a shortcut to a poorly-specified idea. The quality of the output depends entirely on the quality of the direction. What I bring is the product intuition, domain expertise, and process discipline to direct the system well — and the hands-on testing to catch what automated review misses. If you're a founder, startup, or small business who needs a working product built fast and without a $100K agency invoice, I can help. I've done it. I have the receipts. Typical engagements: - iOS app (concept through App Store): 2–4 weeks - Web app or MVP: 1–3 weeks - Landing page + content system: 3–7 days - Full product build (design + dev + content + launch): 3–6 weeks I take a limited number of projects at a time to maintain quality. If you have a clear product idea and need it built and shipped, send me a message describing what you're building.

Then real users arrive: costs balloon, outputs hallucinate, and there's no visibility into why. Production AI requires a different discipline: grounding, observability, systematic evaluation, not just an API call to a thin LLM wrapper. That discipline is what I'll bring. I can tell you exactly what type of AI tooling you require for your specific solution. I can help you determine the technical feasibility of your AI project 𝘣𝘦𝘧𝘰𝘳𝘦 you spend valuable time and money pursuing it. I'm here to make sure you and your team get what you need from AI technology.

I instrument observability, build eval frameworks, and optimise systematically so you know what's working, what isn't, and why. - Full-stack ownership: I can own the AI layer, the API, and the frontend. No coordination tax between specialists; one engineer who sees the whole system, a full-stack developer who owns the AI layer, the API, and the frontend. - Communication that matches your pace, async-first with structured updates, or high-touch with regular syncs. I adapt to how your team works, not the other way around. - Clarity from ambiguity: I have built production systems from partially-defined requirements many times.
