Design Thinking

Design Thinking for Software Engineers

Learn how to think, design, and reason about systems like a senior engineer. Master design thinking fundamentals, problem-solving frameworks, trade-off thinking, and architecture patterns that keep systems adaptable and scalable.

What Is Design Thinking in Software Engineering?

Learn how design thinking transforms unclear product requirements into practical, reliable, and scalable system architectures. Master the skill that differentiates junior engineers from senior ones.

Structured Problem-Solving Framework: The 7-Step Approach

Master the 7-step design framework that FAANG engineers use in real design reviews. Learn to clarify requirements, identify constraints, sketch architecture, and evaluate trade-offs systematically.

Intermediate20 min

Trade-Off Thinking: The Heart of Design Thinking

Great engineers don't pick technologies—they pick trade-offs. Learn how to justify architectural choices like Redis, Kafka, MongoDB, or MySQL with measurable reasoning.

Intermediate25 min

Architecture Thinking: Decomposing Problems into Components

Learn how to break down vague product problems into API flows, storage layers, caching layers, queue pipelines, and background workers. This skill differentiates junior engineers from senior ones.

Real-World Design Templates

Templates help you avoid blank-page syndrome. Reusable thinking models speed up reasoning in interviews and real work.

Beginner18 min

Case Studies in Design Thinking

Learn from real-world systems: Instagram's sharded MySQL, WhatsApp's Erlang architecture, Uber's dynamic pricing, Slack's WebSocket management, and Netflix's microservices migration.

Advanced30 min

High-Level Architecture Patterns

Learn the big patterns you'll repeatedly use in real products and interviews: event-driven architecture, layered architecture, CQRS, microservices, real-time systems, and batch-processing systems.

Intermediate25 min

Anti-Patterns & What Not To Do

Knowing what not to do improves your design instincts faster. Learn to avoid over-engineering, under-engineering, premature optimization, and other common mistakes.

Intermediate20 min

Communication & Interview Strategy

Design thinking is useless unless you communicate it well. Learn how to speak clearly, structure thoughts, and demonstrate senior-level confidence in system design interviews.

Beginner18 min

Decision-Making Under Real Constraints

Senior engineers excel at architectural decisions under uncertainty. Learn time vs correctness vs cost trade-offs, build vs buy vs defer, and MVP vs long-term architecture.

Failure-First Design Thinking

Design for failure before scale. Learn failure modes, blast radius analysis, graceful degradation vs hard failure, and SLOs/SLIs/error budgets in system design.

Senior LensAdvanced24 min

Trade-offs at Scale

Beyond buzzwords: when microservices are wrong, when eventual consistency fails, and how to choose strong consistency, latency vs throughput, and read vs write amplification.

AdvancedReal-World Trade-offAdvanced26 min

Cost-Aware Architecture

Design systems with cloud cost in mind. Over-engineering vs under-engineering, cost of reliability, and when cheaper infrastructure is the wrong choice.

Evolutionary Design

Design for change, not perfection. Migration strategies, schema evolution, backward compatibility, incremental rollouts, and feature flags. Staff-level thinking.

Ambiguity Handling & Problem Framing

How senior engineers ask clarifying questions, reframe vague problems, identify the real vs stated problem, and recognize premature optimization.

Non-Functional Requirements Deep Dive

Security vs UX trade-offs, compliance (PII, GDPR, SOC2), multi-region vs multi-AZ, and observability as part of system design. Senior interview gold.

Team & Org-Level Design Thinking

Design systems for team ownership. Conway's Law in practice, API contracts between teams, reducing cognitive load, and Amazon's two-pizza team. Staff+ signal.

Interview-Specific Senior Mistakes & Anti-Patterns

What senior candidates get wrong in system design interviews. Over-engineering, jumping to tech before clarifying, failing to justify trade-offs. How to avoid these pitfalls.
