À propos de l'application

Your career and your toolbox in one pocket-sized, interactive book, written for working software engineers.

LEARN BY DOING
• 43 interactive labs: slide Big-O inputs, simulate an LRU cache, tune a Kubernetes rolling update, watch consistent hashing move keys, build a STAR story, size an incident
• Step-through visualisers for data structures and algorithms: four sorting algorithms, heaps, union-find, linked lists, BFS and DFS, Dijkstra, topological sort, dynamic programming
• Quick checks inside every chapter, so you test yourself right after you read
• Missed questions come back on a spaced-review schedule until they stick
• 451 quiz questions with explanations, plus a daily question and streak

THE WHOLE CAREER PATH
• What each level expects, from aspiring engineer to junior, mid-level and senior, then on the IC path (Staff, Senior Staff, Principal, Distinguished) or the manager path (Engineering Manager, Senior Manager, Director, VP)
• Onboarding, code reviews, scoping features, design docs, RFCs and ADRs, promotion cases, feedback, incidents and on-call, behavioral interviews and the Staff archetypes
• A quick level quiz across five competencies that shows where you are and what to work on next
• Fill-in templates for design docs, RFCs, ADRs, postmortems, brag docs and more

THE TECHNICAL ARSENAL
• Core CS: Big-O, data structures, sorting and searching, graphs, dynamic programming, coding patterns
• System design: latency numbers, diagramming (C4, sequence diagrams), API design, caching, databases, scaling, messaging, observability, the interview
• Tools: Git, testing, the shell, SQL, regex, HTTP, Docker and Kubernetes, with syntax-highlighted examples
