Built 4 AI apps solo this year. 3 production web apps (CATS_UP, RELISH, BBQ_e), and 1 ChatBot from ground up in Beta. React Native + Python
What I built
4 AI apps in one year, built 0 solo mio:
Production Web Apps (3)
CATSUP (3,6,9) — Socratic AI tutor
Students learn by reasoning through problems, not memorizing answers. K-12 to college.
React Native + FastAPI + multi-model AI.
→ https://www.cats-up.app
RELISH (3,6,9) — Emotional intelligence AI
3-sentence answers to life questions. Relationships, anxiety, decisions. Direct, actionable, real.
React Native + FastAPI + multi-model AI.
Status: Play Store approved. App Store launch next week.
→ https://www.cats-up.fun
BBQ_e (3,6,9) — Mobile cybersecurity
Scan links for phishing, check breach exposure, test WiFi security. No bloatware.
React + Python + AI threat classification.

Custom ChatBot (1)
Sol Calarbone 8 — Custom conversational AI companion
Multi-model orchestration, custom personality, memory persistence.
Status: Beta. Demos available upon request.

Ohad, shipping four distinct AI applications solo in a single year—spanning Socratic tutoring to multi-agent orchestration—is a massive testament to high-velocity engineering. By leveraging a lean React Native and FastAPI stack to move from "build" to "approved" across different domains, you've created a definitive blueprint for the multi-app ecosystem model.
I’m currently running Tokyo Lore, a project that highlights high-utility logic and validation-focused tools like yours. Since you’re building the definitive portfolio of agentic AI solutions, entering one of your production apps could be the perfect way to turn your "solo mio" journey into a winning case study while your odds are at their absolute peak.

That’s a solid pace — shipping multiple apps solo is no joke.
Curious how you’re managing consistency across them, especially on the backend side (Python services, APIs, etc.) once things hit real users.
Do you standardize a lot of your stack/workflows or treat each app differently?
ScamR, i standardize as much operationally as possible. so i default to backend py||js/react/vite/github/railway/claude. the only switch is then app store vs web. then expo/eas in swapped in. changing models is simple as well. i just find claude superior in general.
