Drop The Routine can be fully white-labeled for businesses and clinics. This version was customized for a prominent sports physical therapy group here in Southern California — giving their patients (and athletes around the world) a seamless way to follow prescribed physical therapy routines, complete with videos, instructions, and progress tracking. It allows practitioners to: 🏥 Assign step-by-step recovery routines directly to patients 📱 Track engagement and outcomes through the app 💬 Educate patients between visits and reinforce accountability Built with React Native and AWS — scalable, branded, and deployable in days.

Excited to share this one! Drop The Routine is a web and mobile platform where routines can be built, shared, monetized, and followed. It gives creators and specialists a new way to turn their expertise into income — and gives their followers structured, step-by-step routines designed for real results. Built-in progress tracking helps users stay consistent and accountable. From skincare and haircare to fitness, nutrition, and personal finance — Drop The Routine empowers creators across every niche to help their audiences follow through. This screen shows the creator landing page — where we introduce the platform’s vision and invite experts to join early. I built this with React/Chakra UI/Next.JS, all served and hosted on AWS infrastructure.

I built Didja — a minimalist habit tracking app — to help me achieve my longterm goals by holding me accountable to daily action. It lets users define their goals, create daily or weekly routines that support them, and stay accountable through simple, structured tracking that promotes action. I designed it to be clean, distraction-free, and genuinely enjoyable to use. I finished it a few months ago, but I still use it everyday!
