About Iain

I’m a Senior Full-Stack Engineer & MVP Builder with 8+ years of experience shipping products from idea → scale across healthcare, fintech, logistics, and creator tools.

I specialize in turning messy early-stage problems into clean, working software. That means:

Building full-stack apps with React, Next.js, Node.js, TypeScript, Supabase, MongoDB

Designing scalable APIs & cloud infra (AWS, Azure, Terraform)

Integrating AI/LLM workflows (LangChain, RAG pipelines, Claude, OpenAI, Cursor AI dev flows)

Creating polished UI systems (Tailwind, shadcn/ui, Storybook, design tokens)

💡 Recent wins:

Built a Google Calendar + Supabase integration that auto-preps meetings with strategic checklists.

Led dev for a fintech MVP that validated product-market fit and raised pre-seed in <60 days.

Designed a supply-chain scheduling dashboard (React + GraphQL) used by enterprise clients.

🔑 What you get when working with me:

Fast MVP turnaround (2–4 weeks) → so you can test with real users.

Founder-style thinking → I don’t just code, I refine the product with you.

Scalable, production-ready code → not throwaway prototypes.

Whether you’re a startup founder looking to validate an idea or a scaling team needing fractional CTO firepower, I’ll help you ship faster, smarter, and cleaner.
