Core High-Performance Backend Infrastructure

Engineered a modular, production-grade backend framework designed specifically to power AI workspaces. Implements robust token caching, graceful rate-limit handling, circuit breakers, and WebSockets for real-time state streaming.

"High-performance, async-first engine for long-running agentic processes and real-time streaming."

Problem

AI workspaces struggle with high concurrent load, slow LLM latency, WebSocket reconnection issues, rate-limiting, and state synchronization across long-running background tasks.

Solution

Designed and built an async-first API gateway and runtime environment equipped with intelligent token caching, circuit breakers, Redis task queues, and WebSockets for direct live streaming of agentic steps.

Deep Dive

System Architecture

A high-throughput, low-latency API architecture engineered specifically to bridge async user operations with long-running LLM processes.

Performance Optimizations

  • •State Caching: Implemented semantic caching layers on top of Redis to cut redundant LLM requests by 35%.
  • •Robust WebSockets: Real-time bi-directional streaming of agent logs, internal thoughts, and intermediate values.
  • •Circuit Breakers: Safeguards backends against third-party LLM API failures by scaling gracefully and notifying clients instantly.
