The Problem
Generic fitness apps hand out the same plan to everyone. Elite programming is locked behind expensive coaches. The middle is empty.
The AI Architecture
3x.fit is an AI-personalized performance platform — pro-grade programming that adapts to your actual data so every session compounds.
What Aaron Shipped
- AI-personalized strength and conditioning blocks
- Adaptive progression based on real performance, not vibes
- Pro-grade programming, accessible to everyday athletes
- Built around outcomes — capability, not vanity metrics
The Outcome
Closes the gap between generic fitness apps and expensive private coaching — measurable performance gains for serious people who don't have a coach.
The architect's edge
400+ pieces of software architected.
Aaron has architected 400+ pieces of software across ventures, agencies, and Fortune 500 transformations. The skills and business acumen behind that volume are unmatched — and they show up in every system below.
Browser layer
React 18 · TypeScript 5 · Tailwind
Declarative UI, compile-time type safety, design-token CSS that flips themes from one variable.
Build layer
Vite · esbuild · SWC · imagetools
Native ES modules in dev (instant reloads) and tree-shaken, code-split, hash-versioned bundles in prod.
Edge & delivery
Global CDN · HTTP/3 · TLS 1.3 · immutable caching
Every byte served from the user's nearest PoP. Long-lived caches because filenames are content-hashed.
Backend layer
PostgreSQL · PostgREST · RLS · JWT auth · Deno edge functions
Your schema is your API. Authorization enforced inside the database. Server code without server ops.
None of this is proprietary magic. It's the modern open web — selected, sequenced, and shipped by an architect who has done it 400+ times. That's the genius: knowing exactly which piece to use, when, and why it pays off three quarters from now.
"I've used every fitness app on the market. This is the first one that actually adapted instead of pretending to. My numbers moved."
