Understand
I start with the business problem, not the stack. Half-formed ideas get turned into a scope someone can actually agree to before any code is written.
Open to new opportunities
I turn half-formed ideas into software people actually use.
I'm Keegan. Eight years building web applications, SaaS platforms and automation systems with React, Next.js, Node.js, Python and Supabase. Lately most of my work is AI: LLM-powered agents, chatbots and prompt engineering that solve real business problems rather than just demoing well.

About
Implementation experience, product judgment, and hands-on delivery.
I'm a full-stack and AI developer with about eight years of experience building web applications, SaaS platforms and automation systems that actually get used, not just launched.
My day-to-day toolkit is React, Next.js, Node.js, Python, Laravel and Supabase. Over the last couple of years a lot of my work has shifted toward AI: building LLM-powered agents, chatbots and prompt engineering systems that solve real business problems rather than just demoing well.
What I enjoy most is taking a complex, half-formed idea and turning it into something people can actually use, whether that's an early MVP or a fully deployed platform. I care as much about how a product feels to use and how fast it runs as I do about whether it works, because those things usually decide whether a business actually benefits from it.

How I work
Built to be used, not just launched.
Build
Full-stack delivery end to end — interface, API, database, auth, integrations and deployment. One person accountable for whether the thing works.
Sustain
Performance, security and how the product feels to use decide whether a business benefits from it. That work continues after launch, not just up to it.

Questions
Things people usually ask.
Are you available for new work?
Yes — open to full-time roles and selected contract work, based in Chandler, AZ and comfortable remote or hybrid. Email is the fastest way to reach me.
What do you work with?
React and Next.js on the front, Node.js, Python, FastAPI, Laravel, PostgreSQL and Supabase behind it. Recent work leans heavily on LLM agents, the OpenAI API and prompt engineering.
What does the AI work actually involve?
Building LLM-powered agents, chatbots and automated workflows that solve a specific business problem — prompt engineering, external API integration, and the plumbing that makes them reliable enough to put in front of real users.
Can you take something from idea to launch?
That's most of what I do. Scope, interface, API, database, auth, integrations, deployment — from an early MVP through to a fully deployed platform.
