Deep dive into a past project
Deep Dive: Past Project You Led or Owned
Provide a thorough walkthrough of a project where you had ownership or leadership responsibility. Your presentation should cover the following aspects:
1. Problem and Context
- What specific problem were you solving and for whom?
- Explain the importance of this problem, detailing its business and user impact.
- Identify key constraints that influenced the project, such as time, budget, compliance requirements, and Service Level Objectives (SLOs).
2. Architecture Overview
- Present a high-level system diagram, describing its main components and the flow of data.
- Detail the technologies, data stores, communication protocols, and the deployment model utilized.
3. Critical Design Decisions
- Discuss the major architectural or design choices you made and any significant alternatives considered.
- Articulate the reasoning behind your decisions, including the trade-offs evaluated (e.g., latency, cost, complexity, reliability, team skill set).
4. Role and Contributions
- Describe your specific responsibilities, the scope of your ownership, and how you collaborated with other functions or teams.
- Highlight specific components you personally designed or built, and any leadership actions you took.
5. Toughest Technical Challenges
- Detail the most difficult technical issues you encountered during the project.
- Explain how you diagnosed and resolved these challenges, including any tools, experiments, or validation methods used.
6. Measurable Outcomes
- Provide quantitative results of the project (e.g., improvements in latency, availability, cost reduction, revenue generation, user engagement).
- Present before/after metrics and describe how these measurements were obtained.
7. Hindsight and Lessons
- Reflect on any trade-offs or decisions you would change if given the opportunity to revisit the project.
- Summarize the principles and practices you learned and would carry forward into future work.
