Technical Insights & Architecture Papers
Deep-dives on high-throughput backend architecture, Python & Django performance, real-time Voice AI, and resilient database modeling.
TCP BBRv3 Congestion Control in Production: Slashing Tail Latency & Bufferbloat for Real-Time LLM Token & Audio Streams
Discover how switching Linux kernel congestion control from Cubic to BBRv3 eliminates bufferbloat and slashes p99 tail latency across WebSockets, WebRTC media, and streaming LLM token delivery.
HTTP/3 WebTransport for Conversational Voice AI: Replacing WebSocket Head-of-Line Blocking with Multiplexed Unreliable Datagrams
On lossy mobile networks, standard TCP WebSockets suffer from head-of-line blocking, delaying audio streams past human conversational limits. Discover how HTTP/3 WebTransport uses QUIC unreliable datagrams to maintain sub-150ms voice pipelines.
WebRTC Selective Forwarding Unit (SFU) Architecture: Packet Loss Concealment, Jitter Buffers, and Simulcast in Voice AI
Lossy mobile networks, bursty UDP drops, and jitter destroy real-time voice AI conversations. Explore how Selective Forwarding Units (SFUs) leverage Opus in-band forward error correction and adaptive jitter buffers to maintain sub-150ms audio streams.
Real-Time Voice Agent Guardrails: Enforcing Sub-150ms Latency Budgets & Hallucination Prevention
Building production conversational voice agents demands sub-150ms audio turnaround while strictly enforcing compliance, safety, and hallucination guardrails. Discover how to architect speculative token verification and sliding-window semantic screening without blocking audio streams.
Linux Kernel TCP/IP Stack Hardening: `sysctl.conf` Tuning for 100,000+ Concurrent WebSockets
Out-of-the-box Linux kernel networking limits drop incoming SYN packets, choke on file descriptors, and exhaust connection queues under heavy real-time traffic. Discover the production sysctl parameters required to sustain 100,000+ concurrent WebSockets on a single VPS.
Multi-Agent Workflow Orchestration: LangGraph State Machines vs. Linear Pipelines with Deterministic Fallbacks
Linear LLM chains break unpredictably when tools fail or models hallucinate argument structures. Explore how to build resilient multi-agent supervisors using LangGraph cyclical state machines, typed schemas, and deterministic human-in-the-loop fallback gates.
