The Fundamental AI launch was happening. Designs were still changing less than a week before go-live. A $1.4B company was coming out of stealth mode, covered simultaneously by AWS and Axios.

My decision concerned managing information flow. I could have just built what came in, delivered it, and finished. The client would have seen progress when it was complete.

Instead, I gave them updates on every small step. This included progress on layouts, components, and minor CSS adjustments. This meant more communication for me, but every stakeholder saw the project evolve in real-time.

That transparency created a feedback loop. They could flag issues early, before problems arose. It also built trust, quickly. They needed someone reliable who kept them informed.

The project launched with no issues. Clear, consistent communication yields this outcome on a high-stakes project.

Cool and beautiful

Wellcue – Comprehensive Health Tracking Mobile App

Wellcue is a production, cross-platform mobile app (iOS and Android) that helps people build and sustain healthy habits by tracking all of their health and wellness data in one place. It's built with Flutter on the frontend and powered by Supabase for the backend — PostgreSQL, authentication, storage, and Edge Functions — and is fully localized in English and Spanish.

Users log and monitor a wide range of health categories: blood pressure readings, exercise activities and duration, nutrition and hydration intake, medication schedules, sleep patterns, and body measurements. Each category supports detailed, timestamped entries and clear progress views, so people can see trends over time and stay consistent.

At the heart of the app is a robust reminder and notification engine. Users create fully customizable reminders with flexible recurring schedules (daily, specific days, or custom intervals) and receive reliable push notifications to keep their routines on track. The system is engineered to handle the real-world edge cases most apps miss: exact-time delivery, timezone-safe scheduling of the next occurrence, deduplication across devices, per-occurrence tracking, and automatic "missed reminder" follow-ups when a scheduled action goes unaddressed. Time-sensitive medication reminders are treated as critical health notifications on iOS.

Engineering highlights:

Reliable scheduled push notifications via a Supabase Edge Function + cron backend (Pushy / FCM), with retry, deduplication, and delivery verification

Strict per-user session isolation, guaranteeing that no data leaks across accounts on shared devices

Subscription and free-trial system integrated with RevenueCat and synced through a server-side webhook

Privacy-first monetization: GDPR/UMP consent flow and non-personalized ads (Google AdMob)

Riverpod state management on a Clean Architecture foundation, with resilient background sync

Full internationalization (EN/ES), including Unicode-safe validation for Latin American input

Wellcue is live and actively maintained on the App Store and Google Play, and meets Apple's and Google's health, privacy, and advertising review requirements.

Flutter with Supabase Edge Functions is a solid pairing here. The part I'd stress-test is a reading logged with no signal, since health data is what users assume is safe the second they hit save. Vitals and medication schedules also tend to want different conflict rules, because...
