About
Hi 👋 I’m Vishnu, a backend engineer who struggled with Low-Level Design interviews despite years of experience. Most LLD resources I found were either PDFs, theory-heavy, or influencer-style content that didn’t reflect how interviews actually work. So I built LowLevelDesignMastery — a visual-first platform where engineers practice LLD the same way interviews happen: clarifying requirements, designing class diagrams, applying patterns, and writing real code. The platform now has paying users across multiple countries, and I’m actively building it in public based on real user feedback. Always happy to chat about backend design, system architecture, or indie building 🚀
