Javier R Felix Vizcarra
@javierrfelixvizcarra
AI-focused software engineer building intelligent, voice-driven full-stack systems and autonomous diagnostics.
United StatesWhat I'm looking for
I’m an AI-focused software engineer with 10+ years of experience building intelligent systems, custom software, and full-stack applications. I specialize in Python, REST APIs, AI/ML integration, and voice technology—turning complex ideas into dependable products.
I’ve architected and deployed VoiceLab pipelines that convert voice input into structured repair instructions using Whisper STT and custom LLM prompting. I also built VoiceAgent, a conversational troubleshooting system integrated via WebSocket into a customer portal, so support becomes real-time and guided.
My work pairs automation with practical engineering: I developed AI-powered diagnostic tools using Python and REST APIs, cutting diagnosis time by 40%. With LangChain-based RAG, I index repair manuals and datasheets to deliver instant, AI-assisted answers for technicians.
Beyond AI, I bring deep electronics repair experience and leadership. I’ve managed teams, improved processes with Python automation, and founded a tech hub where I developed custom systems with Python and MySQL—always focused on precision, innovation, and remote-first collaboration.
