I help startups and growing businesses stabilise, improve, and ship digital products — especially platforms built with AI tools, low-code workflows, and vibe-coded apps on platforms like Replit. If you have a product that was built fast and now needs to be fixed, cleaned up, extended, or made reliable for real users, that’s where I come in. I work with founders and teams to turn fragile MVPs into usable, scalable products by improving UX, fixing broken flows, refining the product strategy, and helping engineering move faster with less chaos. What I can help you with • Stabilising platforms built on Replit, AI app builders, low-code tools, and vibe-coded workflows • Improving broken or confusing user journeys • Turning rough prototypes into production-ready product experiences • Designing and shipping SaaS platforms, internal tools, dashboards, and client-facing apps • Adding AI features that are actually useful to users • Scoping MVPs, prioritising features, and reducing product risk • Leading product execution from idea to launch What clients hire me for • Platform rescue: fixing products that were built quickly but are now unstable, messy, or hard to maintain • UX + product improvement: making apps easier to use, clearer, and more likely to convert • Rapid prototyping: building and testing new features quickly before teams overinvest • AI workflow implementation: integrating OpenAI, automation tools, and smart product experiences into existing platforms • Founder support: helping non-technical or overstretched teams make better product decisions My approach I don’t just make screens look better or build random features. I help clients figure out what is breaking, what matters most, and what needs to happen next to make the product more reliable and more valuable. That might mean: • auditing the product and identifying friction points • redesigning key flows • improving onboarding and conversion • cleaning up the product structure • working with developers to implement better solutions • using tools like Replit, Figma, React, Laravel, Supabase, n8n, OpenAI, and payment integrations to move quickly Types of projects I’m a strong fit for • Startups with an MVP that feels unstable or unfinished • Founders who built fast with AI tools and now need product structure • Teams that need a UX/product partner who also understands implementation • Businesses adding AI features, automation, or new digital services • Companies that need someone to bridge strategy, design, and delivery If your app was built quickly and now needs to be stabilised, improved, or prepared for growth, I can help you get it there.
