Experience Highlights

Founder
Sep 2025 - Nov 20252 months
Project Overview

A polished cross-platform habit-building app available on both Google Play and the iOS App Store, designed to help users build and maintain positive habits with minimal effort. Its AI-assisted onboarding allows users to describe a habit in natural language, automatically generating an appropriate schedule and reminder plan, while an integrated notification system encourages consistency and long-term engagement. The app transforms simple intentions into structured, trackable routines through an intuitive, native user experience.

Responsibilities:
  • Independently designed, built, and released a cross-platform habit-building application from concept and architecture through development, app store submission, and production release on Google Play and the iOS App Store;
  • Built the application with React Native and Expo, using NativeWind for styling and a local SQLite database via Drizzle ORM to support an offline-first experience;
  • Developed an AI-assisted habit setup flow powered by a Cloudflare Worker integrating the DeepSeek API, enabling users to create personalized habits from natural language input;
  • Architected a hybrid notification system combining local notifications with a Cloudflare Worker-powered push notification service to deliver reliable reminders across different usage scenarios;
  • Implemented a subscription model using RevenueCat, supporting monthly and yearly plans while managing premium feature access based on real-time subscription status across both platforms;
  • Owned the entire product lifecycle independently, including UI/UX, data architecture, AI backend, notification infrastructure, monetization, and cross-platform release pipelines with Expo EAS, making all key technical and product decisions.

Project Overview

A SaaS platform that digitizes the service of process workflow, enabling law firms, government agencies, and other legal organizations to manage court document delivery through a unified web and mobile solution. The platform combines a client-facing web application with a location-based marketplace that matches service requests to vetted process servers, while automating evidence collection through GPS tracking, timestamped photos, and digital affidavits. Additional features, including real-time tracking, in-app messaging, a public REST API, and integrations with leading case management systems, streamline legal operations and improve transparency throughout the process.

Responsibilities:
  • Led the migration of a legacy React application to a TypeScript monorepo, introducing end-to-end type safety that reduced runtime errors, improved refactoring confidence, and increased long-term maintainability;
  • Established shared tooling, linting, and build configuration across the monorepo, eliminating duplicated setup and standardizing the frontend development experience;
  • Architected reusable shared libraries for components, utilities, and types within the monorepo, accelerating feature delivery and ensuring consistency across multiple products;
  • Led a cross-team frontend working group, defining architectural direction and driving the adoption of shared patterns, standards, and best practices;
  • Mentored engineers through code reviews, pair programming, and hands-on technical guidance, improving code quality and strengthening TypeScript and modern React expertise;
  • Championed frontend consistency by aligning teams on shared conventions, reducing fragmentation and lowering long-term maintenance costs;
  • Owned the full frontend development lifecycle, from scoping and architecture through implementation, testing, and delivery, for the client-facing platform;
  • Partnered closely with the backend team on API contract design, shaping request and response schemas and data models to ensure seamless integration, reduce rework, and maintain alignment throughout development.
