Two engineers building products they actually want to use.

We're Corneliu and Anthony. We spent years designing and shipping production-grade generative AI systems — scalable cloud architectures, applied AI for enterprise customers. A lot of that work was prototyping: helping customers figure out what was possible, what was production-ready, and what was just hype.

Somewhere in that work, a pattern emerged. The same problems kept showing up. The same gaps. And we started thinking: if we're solving this over and over for different customers, maybe it deserves a proper solution.

That's how we build. We don't start with ideas — we start with problems we've seen firsthand.


What We Ship

Agent Squad — Open-source multi-agent orchestration framework

Flexible, lightweight framework for orchestrating multiple AI agents to handle complex conversations.

While building AI prototypes for customers, we kept running into the same wall: how do you intelligently route user queries across multiple specialized agents, maintain context across turns, and ship something that actually holds up in production?

There was no good answer. So we built one. We started with a project called multi-agent-orchestrator — and as it grew, it became Agent Squad. We're the authors, the main maintainers, and we're still actively evolving it.

7,500+ GitHub stars. Used in production worldwide.

  • Intelligent intent classification — Routes queries to the most suitable agent based on context and content
  • Context management — Maintains conversation history across agents for coherent multi-turn interactions
  • Streaming support — Real-time responses from any agent type
  • SupervisorAgent — Coordinate teams of specialized agents working in parallel
  • TypeScript & Python — Fully implemented in both languages
  • Universal deployment — AWS Lambda, local, any cloud

Available on npm and PyPI. Source on GitHub.


StreetLens — iOS audio tour app

Every place has a story. StreetLens lets you hear it — in your language.

Same instinct, different domain. We kept having the same experience as travelers: standing in front of something remarkable, knowing there was a story behind it, and having no good way to access it. Not a fixed group tour. Not a schedule. Just — the story of this place, right now, in the language I think in.

So we built StreetLens. An iOS app that gives visitors a personalized audio guide to any place around them.

No account. No advertising. Just put in your headphones and walk.


Q Developer Wrapper — SDK for Amazon Q Developer CLI

A lightweight SDK that enables seamless integration of Amazon Q Developer CLI into your applications, scripts, and automation workflows. TypeScript & Python, real-time streaming, cross-platform.
