Senior engineers think in blast radius. Before shipping: * Who does this affect? * How bad is failure? * How fast can we recover? Speed without containment is recklessness. #EngineeringLeadership #SystemDesign

In der Wirkungsökonomie sprechen wir oft über abstrakte Systeme, CO2-Bilanzen und Kapitalströme. Aber Systeme wirken immer auf den kleinsten gemeinsamen Nenner: den Menschen und seinen Körper. 🧵 #Wirkungsökonomie #Systemdesign #Selbstbestimmung

Day 2/100 of Interview Prep Challenge 🚀 Moving from "Cost" to "Scale." Today was all about CDNs & Edge Caching—learning how to serve users globally without melting the origin server. #100DaysOfCode #BuildInPublic #SystemDesign #InterviewPrep

🚀 Learning System Design in Public — Day 10 So far I’ve learned a lot about caching inside backend systems. But one big question remained: How do systems serve users quickly across the entire world? That’s where CDN Caching comes in. #SystemDesign #Backend

Key takeaway: Multi-leader replication can boost availability and performance but at the cost of consistency and complexity. Understand your use case and implement robust conflict resolution strategies. Choose wisely! #SystemDesign

The most flexible systems are those in which source code dependencies refer only to abstractions, not to concretions. - Robert Martin #software #programming #systemdesign

Built a real system. Not a project. Handled researchers, payments, and deadlines for RACS 2026. Live conference platform → racs2026.in End-to-end. In production. This is what I want to keep building. #FullStack #Backend #SystemDesign

We are seeing a hard pivot from "Autonomous" to "Governed" agents in regulated industries. 📉🚀 Would you trust an autonomous agent to plan a city's 5G grid, or is "Governed AI" the only safe path forward? Let's discuss! 👇 #TelcoAI #PhysicalAI #SystemDesign #EdgeComputing #raNora #Aircom
