Cover image for Built an end-to-end lead capture
Built an end-to-end lead capture and follow-up automation triggered by a Voiceflow chatbot. The workflow parses and formats user inputs, logs each lead to Google Sheets for tracking, sends an internal notification via Gmail, and syncs the contact into Mailchimp with custom fields for segmentation and automated nurturing. This system reduces manual data entry and ensures every lead gets captured, routed, and followed up consistently within minutes. Highlights Voiceflow trigger (Custom API Response) → workflow automation Data parsing/formatting (split fields) for clean CRM-ready inputs Lead logging to Google Sheets + internal email notification Mailchimp contact creation with custom fields for tagging/segmentation

FastMind is a fasting tracker I built with product-grade logic — not a basic stopwatch. The app treats fasting as a structured workflow with multiple states (e.g., started, active, paused, ended), and persists time correctly across sessions. Users can log notes and mood states during a fast, creating a dataset that the AI layer can summarize into useful insights and patterns over time. What makes this non-trivial Reliable fasting time calculations + persistence (not just UI) State-driven flow handling edge cases (pause/resume/end scenarios) Notes + mood tracking tied to the fasting lifecycle AI-generated summaries and insights based on user entries Clean UX built on top of complex underlying logic
