Real senior Python interview questions from a top outsourcing company in Vietnam — covering data structures, memory management, async concurrency, database optimization, and code quality.

Most developers struggle not because they lack technical skill, but because they can't communicate clearly upward. Here's a practical framework for talking to your manager with precision and confidence.

Every software project exists to solve a real-world problem. But developers aren't domain experts — and that gap is exactly why you need someone who is, sitting with you from day one through delivery.

Coding is just one tool in a developer's toolkit. The real job is solving problems — and that means adapting to any tech stack, understanding the business, and thinking beyond syntax.

Learn how to write effective design documents that clarify thinking, surface trade-offs, and drive better technical decisions. Includes templates, real examples, and a framework for when to write one.

Companies are cutting junior roles and investing in AI, but they're destroying the pipeline that creates senior engineers. Why this 'structural collapse' threatens the entire tech industry by 2030.

A personal reflection on my VNG fresher program in 2012 — the 6 months that taught me more real-world engineering than 4 years of university. From Windows to Linux, C# to Java, SQL Server to Redis.

A curated list of pet projects that actually build real full-stack skills — from URL shorteners to real-time chat apps. Each project targets specific technologies and grows your portfolio with something worth showing.

The developers who never get replaced share specific habits: they do excellent work, love fundamentals, wire learning to their jobs, seek challenges, and intentionally improve over time.
