I am currently a Software Engineer II at Microsoft, building the M365 Copilot mobile app. Previously, I was an SDE at Amazon, where I engineered highly available distributed backend systems that processed billions of dollars in transaction volume. Because my career spans from building native mobile apps from scratch to architecting fault-tolerant backend microservices, I understand system design from end to end. The biggest hurdle to breaking into FAANG/Big Tech isn't just knowing how to code - it's knowing exactly what interviewers are looking for. During my time at Amazon, I conducted 50+ technical interviews for SDE roles. I know the exact difference between a "strong hire" and a "reject," and I know how to help you demonstrate the technical depth and leadership signals that top companies demand.
