He emphasizes that management is a "side step" not a "step up" from an Individual Contributor (IC) role. The conversation moves into why engineers often leave jobs after two years, the importance of finding fulfilling work, and how a colleague's comment ("planted the seed") and the book "Staff Engineer's Path" helped him pursue the promotion.A significant portion covers Santhosh's personal health journey after a Type 2 diabetes diagnosis, which led him to prioritize health, drop conference speaking, and take up running. He shares his progress from struggling with 3km to completing a half marathon, emphasizing listening to his body, proper gear, rest, and not comparing himself to others. This inspired him to launch devswhorun.dev to motivate other developers.Other topics include:- The value of validation and good managers.- Dealing with toxic work environments (advice: leave).- Productivity while working from home.- His podcast "This is Tech Talks" and interest in home automation.The core message: cherish what you have and the importance of health for sustainable impact.Chapters00:00:00 Santosh Yadav00:04:31 Introduction and Guest Welcome00:05:31 Career Progression and Promotion Journey00:11:36 The Importance of Staying in One Place00:15:21 Understanding Solonis and Its Impact00:19:29 The Role of a Staff Engineer00:24:29 The Value of Validation in Career Growth00:31:31 Balancing Health and Career00:39:44 Conclusion and Future Aspirations00:40:39 Fitness Journey and Personal Records00:41:31 The Impact of Niceness on Management00:45:25 Transforming Toxicity into Calmness00:50:25 Building Connections Beyond Work00:52:55 The Importance of Compassion in the Workplace00:54:39 Work from Home vs. Office Productivity00:57:59 Exploring AI and Home Automation01:07:37 The Evolution of Angular and Personal Health Journey01:10:11 Health Transformation and Running a Half Marathon01:16:38 The Journey of Personal Growth Through Running01:20:23 Understanding the Importance of Recovery and Rest01:22:32 Choosing the Right Gear for Running01:25:12 Leveraging Technology for Training and Recovery01:33:36 Community Building Through Shared Experiences01:36:16 Transforming Personal Challenges into Community Impact

Follow me on 𝕏: https://x.com/tejaskumar_This podcast episode dives deep into the world of Event Sourcing, a powerful architectural pattern used in modern software development. Beginning with a clear definition of Event Sourcing, the episode explores its roots in Domain Driven Design and its critical role in recording and storing every change made to the state of an application in an event store. I break down complex topics, such as the nature of events, the intricacies of implementing Event Sourcing in real-world applications, and the various benefits and challenges associated with this approach.Listeners will gain insights into the practical aspects of Event Sourcing, including detailed discussions on storage costs, computational expenses, and the practice of snapshotting to optimize performance. The episode also covers the concept of event ownership, Command Query Responsibility Segregation (CQRS), and ensuring data consistency using Apache Kafka, a distributed event streaming platform known for its high throughput, reliability, and scalability.Further, the episode delves into Kafka's performance mechanisms, its use as an event store, and the transition from Zookeeper to KRaft for cluster coordination. Alternatives to Kafka, such as using Postgres' Write-Ahead Logging (WAL) as an event store, are examined, providing listeners with a comprehensive view of the options available for implementing Event Sourcing.The discussion extends to real-life use cases of Event Sourcing, highlighting its application across various industries and projects. The experts also tackle some of the common problems encountered when adopting Event Sourcing, offering practical advice and solutions. Finally, the episode concludes with a thoughtful analysis on whether Event Sourcing is the right choice for your project, helping listeners to make informed decisions based on their specific needs and project requirements.This episode is a must-listen for software developers, architects, and technology leaders looking to understand Event Sourcing, its benefits, challenges, and implementation strategies. Whether you're new to Event Sourcing or looking to refine your existing knowledge, this episode provides valuable insights into making the most of this powerful architectural pattern.Chapters00:00 - Intro03:33 - Sponsor (CrabNebula.dev)04:21 - Defining Event Sourcing07:47 - What are Events?
