I built several interconnected components inside a unified AI chatbot SaaS platform designed to automate complex workflows across multiple industries. One of the core modules is an EV diagnostic system that allows users to select their vehicle, describe symptoms or enter error codes, upload photos, and receive an AI‑generated diagnosis with severity, probable causes and recommended next steps. The system also connects to a product and service catalog, enabling the assistant to suggest compatible accessories such as chargers, cables, auxiliary batteries, boosters, wallbox installations and safety equipment. The entire flow is multilingual, available 24/7 and optimized for natural‑language interaction. I also developed the voice automation layer of the platform, integrating real‑time call logs, cost tracking, call‑end reasons, timestamps and assistant performance metrics. This module supports AI voice agents used for support, claims and customer operations, giving teams full visibility

I contributed multiple modules to a full AI Chatbot SaaS platform designed to automate communication, operations, and customer workflows across different industries. 1. AI Voice Automation (VAPI Call Logs & Monitoring) I implemented the call‑tracking and analytics layer for the platform’s voice AI system. This includes real‑time logs for outbound calls, showing call IDs, assistant identity, customer numbers, call type, end reason, timestamps, duration, and cost. This module integrates directly with the platform’s Assistants, Squads, Tools, Phone Numbers, Metrics, and API Keys, giving operators full visibility into AI‑driven conversations. 2. Claims Automation – Insurance Company Management I built the company‑management dashboard used in the platform’s automated claims workflow. Operators can sync phone numbers, add/edit insurers, manage working windows, and toggle active/paused states. This module powers automated ticket routing and AI‑driven communication with insurance com

I developed and integrated two operational modules for an AI‑driven communication and claims‑processing system. 1. VAPI Call Logs & Monitoring Module I implemented a real‑time call analytics dashboard that displays outbound AI‑assistant calls, including call ID, assistant identity, customer number, call type, end reason, timestamps, duration, and cost. The system supports detailed monitoring for each call, enabling teams to audit performance, detect issues (e.g., silence, customer hang‑ups), and optimize assistant behavior. The module is fully integrated with VAPI’s Assistants, Squads, Tools, Phone Numbers, Metrics, and API Keys sections, ensuring seamless observability across the entire voice automation pipeline. 2.

designed and implemented a mobile solution that transforms traditional paper forms into fully interactive smart mobile forms. The project included creating digital versions of work orders, jobsite inspections, and field reports with support for images, sketches, maps, and digital signatures. The interface was optimized for field technicians, enabling fast data entry, photo capture, and real‑time syncing. The system also integrates with external business applications, allowing automated workflows, centralized data storage, and improved operational efficiency.

I created a promotional UI/UX showcase for a food‑focused social networking mobile app. The design highlights the app’s core features, including location‑based restaurant discovery, reviewer following, video review feeds, in‑app ordering, and user‑generated ratings. Each screen was crafted to clearly communicate functionality while maintaining a clean, modern visual identity. The layout uses a warm color palette, intuitive navigation, and high‑contrast elements to ensure clarity and engagement. This project demonstrates my ability to translate complex app features into a visually compelling and easy‑to-understand presentation.

Architected and developed a full-stack platform for buying, selling, and managing fine wine as an asset class. The system solved complex problems unique to alternative assets: **provenance tracking** (chain-of-custody recorded on a private blockchain ledger for high-value lots), **condition grading** (users submitted cellar photos analyzed by computer vision to suggest storage quality), and **dynamic valuation** (integrating auction API data, critic scores, and market demand signals). The marketplace backend (Node.js, Postgres) handled bid/ask order matching and escrow services. The core for users was the "Digital Cellar" – a React frontend allowing collectors to catalog bottles, view estimated portfolio value over time, and get AI-driven selling recommendations ("Drink, Hold, or Sell") based on peak maturity windows. A standout B2B feature was the "Trade Liquidity Pool" API for wine merchants, enabling them to programmatically list and source inventory. T
