I built a multi-tenant WhatsApp AI assistant that lets businesses manage conversational agents from a shared dashboard. It supports text, image, and voice interactions, including Whisper transcription and ElevenLabs-generated speech.

As an independent developer, I also built an Instagram outreach engine using Playwright and a Pinecone-based RAG pipeline. I delivered mobile and web applications for healthcare, retail management, and service-booking platforms, and reduced application startup time from approximately 5 seconds to under 2 seconds.

At Jam Juggler, I delivered 8+ client applications and developed reusable Flutter UI components. I also worked on YourCoach and GoJoe, and built PGS Learning as a Flutter, web, and backend platform with offline-first video delivery.
