Founding engineer at Youe, where I work on LLM and agent backends in Python and the React 19 frontends in front of them.
What I'm on right now:
- AxonPush. Open source observability for agent and inference runs. Has Python and TypeScript SDKs and an OpenTelemetry exporter, plus glue for LangChain, OpenAI Agents, Anthropic, and CrewAI.
- Athena at Youe. A streaming voice agent for salary-negotiation practice, running on SSE and LiveKit.
- A few smaller Go and C++ libraries on the side: MusixScrape, anilistWrapGO, and eru.
Happy to chat about agent observability, distributed systems, or Azure and AWS platform work. You can reach me at me@sayanbiswas.in or DM me on Twitter.
