About

Self-taught Senior Backend Developer with 13+ years of experience building VoIP infrastructure, CRM/business integrations, and AI-powered voice/chat solutions. I lead end-to-end projects, ship event-driven microservice architectures, and ramp up quickly on new technologies without formal training.

I’ve driven large-scale telephony migrations (17,000+ seats across 15 cities), built integrations from scratch (25+ CRMs, 400+ active client integrations), and pioneered LLM/voice bot solutions embedded into customers’ workflows—helping automate call handling, transcription, and support experiences.
