Backend-focused engineer building systems, tools, and autonomous agents, mostly the kind that behave differently once more than one person shows up.

WHAT GETS INTERESTING

I enjoy systems most when the happy path stops being enough.

I like the moment a system stops being simple - state disagreements, backed-up queues, an agent that isn't sure. That's where the real engineering starts for me.

2026SYSTEMS & AI
ASYNC AI INFRASTRUCTUREIN PROGRESS

C-Flux

An asynchronous RAG pipeline that answers questions grounded in a user's own documents, without blocking on parsing, embedding, or inference.

WHAT I LEARNED

Separating requests from expensive work

  • Node.js
  • WebSockets
  • Redis
  • Pinecone

AUTONOMOUS AGENTSSHIPPED

CarbonCopy

An AI agent that represents me and knows when to involve me directly instead of guessing on my behalf.

WHAT I LEARNED

Designing for uncertainty

  • Python
  • LLM APIs
  • Custom Agent Logic
  • Gradio

ENGINEERING CURIOSITIES

01CLOSED

How do AI agents actually work without abstraction libraries?

02OPEN

What actually happens when a WebSocket connection dies mid-operation?

03OPEN

How much autonomy should an AI agent really have?

04OPEN

When does a Redis queue become a problem instead of a solution?

05OPEN

What should happen when the system doesn't know?
