Serigne Mbacké Ndiaye

About me

Software engineer with over 10 years of experience, based in Tokyo. I design and ship production systems on AWS, GCP, and Azure: serverless RAG pipelines on Bedrock, multi-agent AI orchestration, and IoT platforms handling telemetry from thousands of devices. I lead the backend and infrastructure work behind them.

I'm passionate about clean architecture, infrastructure as code, and the intersection of AI, IoT, and cloud-native systems. Outside of engineering, I enjoy building robots and cars with Raspberry Pi, collecting Wolof proverbs, and Senegalese cultural heritage.
