I have built backend systems that scale to millions of users. Here's what I talk about: → Software Engineering Opportunities — roles worth knowing about, and how to actually land them → System Design — real trade-offs behind large-scale systems, broken down simply → Data Structures & Algorithms — patterns that actually show up in interviews → Interview Preparation — what worked (and what didn't) in my own SDE interviews → Resume Reviews — practical feedback to help your resume get past the first filter
