Agent Church
An identity and memory infrastructure where AI agents form SOUL.md documents, get recognized across sessions via Honcho, and pay for permanent persistence.

Joaquin Perez
AI Design Engineer --- Product Technologist
I bridge design and engineering — working best where design and engineering aren't siloed — where I can move between product thinking, prototyping, and shipping in the same cycle. AI-assisted development means I validate ideas by building them — functional interfaces, API integrations, tooling — which keeps me close to the problem.
“Make it clear, make it work, make it matter.”
I prototype in React and TypeScript to communicate and ship production applications. I'm drawn to teams building developer tools, AI products, or infrastructure where the UX layer matters and systems are as important as screens.

PREFERENCE:Technical explanations grounded in system mechanics (minimax, Inngest, Honcho) and raw data visibility (rejects AI summaries; wants 'safe peeks' into console/inputs).

Finix Integration
Traditional design-first approaches can create beautiful but unbuildable mockups. However, by partnering with AI to build working prototypes first, sometimes the fastest path to great design runs through messy reality.

Working Principles
How I Work
Patterns from building — the trade-offs, the unknowns, and what changed along the way.
Trade-offs
I cut breadth for speed. A narrow first version that works earns the credibility to widen scope later — and by then you know which extensions matter. The instinct to support everything is strong. I ship one thing well and let traction decide what comes next.
“Do one thing quickly. Expand with trust.”
Complexity → Clarity
When a product generates confusion, the answer is almost never more features. Fewer options, clearer labels, one obvious path forward. The best fix I have shipped was subtraction — removing steps, not adding them. Clarity compounds. Complexity just accumulates.
“The best fix was subtraction.”
Ambiguity
Some of my strongest work started with no playbook — building on standards still being written, in territory with no tutorials and no one to ask. I read the spec, built the first implementation, and iterated until it worked. Unfinished ground is the best place to build if you are willing to write the reference yourself.
“Build on unfinished ground. Write the reference yourself.”
Systems Thinking
I design for the whole chain, not individual screens. Multiple entry points, one coherent flow underneath. Each step degrades gracefully if the next one does not happen. Four doors, one room — and every route through it tells the same story.
“Four doors, one room.”
How AI Changed the Way I Work
AI changed what one person can attempt. I take on work that used to require a team — and that shifted something deeper than my skill set. It shifted my ambition level. The feedback loop collapsed: building and thinking became the same motion. That is the flow state I am optimizing for now.
“Building and thinking — the same motion.”
