How I built LeadSysGen, an automated prospect discovery, qualification, and outreach system, the technical architecture, what the LLMs are actually good at, and where they fail.
After two years freelancing across France and Morocco, here's the pricing framework I use, how I handle scope creep, and why charging more often leads to better projects.
How I architected LeadPulse, a full-stack CRM with real-time pipeline tracking, automated follow-ups, and analytics, and the decisions I'd make differently.
TCP-based VPN protocols have fundamental performance limitations. TUIC (QUIC transport) and Hysteria2 (BBR over UDP) solve them differently, here's the technical breakdown of both and when to use each.
Deep dive into designing and deploying anti-censorship VPN protocols optimized for restrictive networks using Xray Core and Golang
What co-founding Vexonik taught me about high-availability distributed systems, anti-censorship protocols, and the engineering tradeoffs of running infrastructure used by thousands of concurrent connections.
