Built the mobile experience for Plotlot, focusing on creating a practical, GPS-driven utility app that helps users understand and manage real-world land and property boundaries with ease. The goal was to design a simple yet powerful interface where users like homeowners, realtors, and surveyors can quickly access property insights, measure land areas, calculate distances, and view approximate boundaries using GPS data. I focused on structuring complex geolocation features into an intuitive flow that makes land visualization and measurement accessible for non-technical users. Special attention was given to usability in outdoor conditions, ensuring the app remains responsive, clear, and reliable during real-time location tracking and mapping interactions.

Built the mobile experience for Crypto Hunters – Hunt to Earn, focusing on creating an immersive, location-based Web3 gaming interface that blends AR exploration with real-world interaction. The goal was to design a smooth and engaging experience where users can hunt digital rewards, complete tasks, and interact with geo-located gameplay elements without friction. I focused on clean UI flows, intuitive navigation, and optimized in-game interactions to make the “hunt-to-earn” experience feel natural and rewarding across different environments. I also ensured performance stability and responsive behavior so the app works seamlessly during real-time location tracking, AR interactions, and reward collection.

Cover image for AI Voice Agents for Healthcare
HIPAA-Compliant

AI Voice Agents for Healthcare HIPAA-Compliant AI Receptionist & Patient Automation Healthcare teams spend countless hours answering repetitive phone calls, scheduling appointments, verifying insurance, and following up with patients. I built AI Voice Agents that automate these workflows while delivering natural, human-like conversations and integrating directly with healthcare systems. Project Overview This project showcases production-ready AI voice agents designed for clinics, medical practices, wellness centers, and healthcare providers. The system can answer inbound calls, qualify new patients, schedule appointments, retrieve patient information, send SMS confirmations, and escalate complex requests to staff when needed. Key Features • 24/7 AI Receptionist • Appointment Booking & Rescheduling • Insurance & Claims Support • Patient Qualification • Calendar Integration • SMS & Email Confirmations • EHR / CRM Integration • Human Handoff • Natural AI Conversations Example Workflows Insurance Support Patients can ask questions about coverage, eligibility, claim deadlines, and policy information. The AI provides accurate responses, sends helpful SMS links, and transfers complicated cases to a human representative when required. Patient Appointment Booking When a new lead submits a website form, the AI immediately calls them, answers questions, checks calendar availability, books an appointment, and sends confirmation automatically. Treatment Scheduling The AI verifies patient identity, retrieves treatment information, checks remaining sessions, and books follow-up appointments without manual staff involvement. Tech Stack • Retell AI • OpenAI GPT • n8n • Make.com (http://Make.com) • Zapier • GoHighLevel • Twilio • Google Calendar • Custom API Integrations Results ✔ Faster response times ✔ Reduced administrative workload ✔ Automated appointment scheduling ✔ Improved patient experience ✔ 24/7 availability ✔ Fewer missed opportunities If you're looking to automate patient communication with AI Voice Agents, I can build a secure, scalable solution tailored to your healthcare workflow.

Problem: Users need a fast, reliable, and secure way to digitize physical documents and extract text without relying on privacy-invasive cloud processing. Solution: I developed ScanIt, a native iOS utility built with SwiftUI and VisionKit. The app provides a professional scanning experience, focusing on high-speed edge detection, automatic perspective correction, and on-device OCR. Key Engineering Highlights: VisionKit Integration: Leveraged Apple’s VNDocumentCameraViewController for seamless, native document capturing with automatic shutter and real-time guidance. On-Device OCR: Implemented the Vision Framework for high-accuracy Optical Character Recognition (OCR), allowing users to search, copy, and share text directly from images without an internet connection. Advanced PDF Processing: Built custom logic for PDF generation, compression, and digital signature integration to ensure documents are office-ready. SwiftUI Performance: Optimized the UI for speed and responsiveness, ensuring large multi-page scans remain fluid and memory-efficient. Privacy-First: Designed the architecture to keep all document processing local to the device, prioritizing user security.
