An AI-powered household productivity app

Manage habits, calendar, todos, grocery lists, and meal plans — with a chat assistant that understands your data and helps you stay on track. The AI uses retrieval-based tool calling to read and write your data, streaming responses in real-time via SSE with a proposal system that never modifies data without confirmation.

02 / AboutNathan deNoyelles

Quick learner who thrives in unfamiliar territory — from enterprise Java to AI-powered mobile apps.

I've spent 8+ years at the NAIC building and maintaining large-scale enterprise applications — designing REST and SOAP APIs, migrating legacy build systems to Maven, standing up GitLab CI pipelines, and deploying to AWS. I progressed from entry-level to Software Engineer III through consistent delivery on high-profile projects.

Now I build my own products end-to-end: from database schema to app store listing. My current focus is AI-integrated apps using Next.js, TypeScript, OpenAI, and Capacitor for Android — deployed on AWS with Terraform. I enjoy shipping complete products solo.
