Featured Orchestrations
High-impact engineering artifacts demonstrating technical depth and architectural precision.
PURE HABIT
A Flutter-native Android habit tracker built around one idea: your progress should be visible without unlocking your phone. Pure Habit renders daily, weekly, and yearly habit streaks directly on the Android lock screen via a native home screen widget, with a Wear OS companion app (upcoming) that keeps your active streak on your wrist. Built with Supabase as the backend and Firebase Cloud Messaging for streak reminders — engineered with web-scale system design thinking applied to mobile.
MCP BUDGET SERVER
An advanced Model Context Protocol (MCP) server that transforms the Budget Tracker into an agentic financial assistant. Integrated with Claude, it enables natural language commands for managing transactions from any terminal. The server is Dockerized and hosted on Render, featuring a deterministic tool-calling architecture that eliminates temporal hallucinations by enforcing real-time date verification.
