Full Automation from Lead to Payment: A Case Study of End-to-End Sales Process Transformation Using n8n and AI

This article provides an in-depth analysis of a real business project—the quote-to-cash automation system built for a Texas window replacement company. Using 7 n8n workflows, Claude AI quote generation, ElevenLabs voice agents, and a Stripe payment closed loop, the system reduces the originally fully manual sales cycle to just one click of approval by the sales manager.

Splinter: A Lock-Free Zero-Copy Shared Memory KV and Vector Storage Library That Eliminates Socket and Memcpy Overhead for LLM Inference

Splinter: A Lock-Free Zero-Copy Shared Memory KV and Vector Storage Library That Eliminates Socket and Memcpy Overhead for LLM Inference

Splinter is a minimalist, high-performance key-value (KV) and vector storage system enabling zero-latency inter-process communication via shared memory and atomic operations. With only 766 lines of core code, it supports millions of operations per second and 768-dimensional vector storage, offering a new architectural approach for local LLM inference and data-intensive applications.
