Mobile-First Inventory & Spatial Mapping
A cross-platform mobile application designed to digitize the logistics of local retail (sari-sari stores). This required architecting a system capable of real-time inventory synchronization and visual shelf-mapping across multiple concurrent users (owners and staff).
Engineered with Flutter for native mobile performance and backed by a robust ASP.NET Core API, the application seamlessly handles complex relational state, role-based access control via Auth0, and live data sharing without degrading the user experience on lower-end hardware.

💜 Smart crypto, designed for smarter decisions.
Created a modern crypto finance mobile app concept focused on making complex market data feel simple, clear, and easy to understand.
I designed the visual experience in Figma and explored the product direction with a strong focus on mobile-first UI, data visualization, and AI-powered insights.
What I explored:
• Crypto finance app UI/UX
• AI-powered market insights
• Portfolio and asset tracking
• Real-time market data interface
• Custom mobile dashboard
• Interactive data visualization
• Clean financial UI
• iOS app presentation
• Custom branding and visual identity
• Product design presentation
The concept combines a clean editorial aesthetic with a bold purple visual system to give the product a modern fintech feel.
Designed in Figma. Built around a real product experience.

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...
