System X Engineering
Hi, I'm Denny — a backend engineer with 13+ years of IT experience (9 years Android, 4 years Java backend).
On this channel, I teach working software engineers how to: ✅ Master Java, Spring Boot & Microservices ✅ Crack system design & backend interviews ✅ Grow into senior roles in India and Europe
No fluff. No theory dumps. Just real production patterns, war stories, and interview-ready breakdowns from someone who's been in the trenches.
