CO-FOUNDER @ CODEXYO · FRACTIONAL CTO @ HAYA TRADING (CANADA)

AMIR AIJAZ AI ENGINEER

Full-stack AI engineer and co-founder of Codexyo, building LLM systems, RAG pipelines, voice agents and computer vision that actually hold up in production. I care about the stuff that matters once real users show up, like cost, latency and reliability, not just a demo that looks good on launch day.
