It can also help prevent bugs and security vulnerabilities from making it into production code, which can save time, money, and resources in the long run.

 

Setting high expectations: To set high expectations for code reviews, I would ensure that all code is reviewed by at least two developers with expertise in the relevant technologies, such as C# .NET Core, Oracle SQL, web services, and AWS Cloud. For example, if we are working on a project that involves building a cloud-based application using AWS Lambda, I would require that all Lambda functions be reviewed by two developers who have experience working with AWS Cloud and are knowledgeable about serverless architecture. In addition, I would require that the code be thoroughly tested before any feedback is provided, by ensuring that the developers have tested the application across multiple environments and that they have written automated tests for their code.

 

Creating a clear and consistent process: To create a clear and consistent process for code reviews, I would establish a standard set of steps and criteria for each review and would use a specific tool or platform to conduct the reviews. For example, if we are using GitHub for version control, I would create a checklist of items to review for each code submission, such as ensuring that the code follows the project's coding standards, that there are no syntax errors or bugs, and that the code is well-documented. I would also use a tool like Code Climate to automatically analyze the code for issues such as complexity and duplication.

 

Ensuring knowledgeable and skilled reviewers: To ensure that reviewers are knowledgeable and skilled in providing feedback, I would provide training and mentorship programs for new reviewers and would regularly practice reviewing code with the team. For example, I might organize a workshop on best practices for reviewing AWS Lambda functions, or pair up junior developers with more experienced developers to review code together. Additionally, I would encourage the team to participate in online communities and attend conferences related to C# .NET Core, Oracle SQL, web services, and AWS Cloud to stay up to date on the latest developments in these technologies.

Imagine you are playing as an architect role in cloud based services for Samsung TV Streaming Project, and your project is breaking production system twice in a month. How do you fix this issue and how to ignore such issue in future by modifying the code review process

 

As the architect for the cloud-based services for Samsung TV Streaming Project, it is my responsibility to ensure that the system is stable and reliable. If the system is breaking in production twice a month, it indicates that there are some serious issues that need to be addressed. Here's what I would do to fix the issue and prevent it from happening in the future:

 

Conduct a thorough investigation: The first step is to conduct a thorough investigation to understand the root cause of the issue. I would analyze the system logs, performance metrics, and other relevant data to identify the specific causes of the production issues. Once the root cause is identified, I would work with the development team to address the issue.

 

Improve the code review process: One of the key ways to prevent such issues in the future is to improve the code review process. I would modify the code review process to include additional checks and balances to catch potential issues before they make it into production. For example, I would add automated testing tools like unit tests, integration tests, and load tests to ensure that the code is functioning as intended. I would also require that all code changes go through a code review by at least two developers, including an architect like myself, to ensure that the code is following the best practices and is aligned with the project's architecture.

 

Implement a production monitoring system: In addition to improving the code review process, I would also implement a production monitoring system to detect issues in production as soon as they occur. This would involve setting up automated monitoring tools that would alert us in real-time when there is a problem with the system. With this system in place, we can quickly identify and fix issues before they have a chance to impact the users.

 

Conduct regular reviews: Finally, to ensure that the code review process is effective in the long term, I would conduct regular reviews of the process itself. This would involve collecting feedback from developers, reviewing metrics related to code quality and system stability, and making continuous improvements to the process over time. By doing this, we can ensure that the code review process remains effective and continues to catch potential issues before they make it into production.

How will you demonstrate the leadership traits as an architect in interview setup. Use real project example as shared to you?

 

As an architect, demonstrating leadership traits is important to inspire confidence in the project stakeholders, team members, and potential employers during an interview. Here's how I would demonstrate leadership traits in an interview, using the Samsung TV Streaming project as an example:

 

Clear communication: Clear communication is a crucial trait of a good leader, especially in the role of an architect. During the interview, I would demonstrate my ability to communicate complex technical concepts in a clear and concise manner. For example, I might explain how I worked with the development team to identify the root cause of production issues by using a specific tool like New Relic or Splunk to analyze the system logs.

As an Engineering leader what are the top 03 critical decision you have taken which is initially not liked by many people but at the end with result it is hugely appreciated by Everyone even the CEO nad CTO of company?

 

Certainly, here's an updated response with Multi-Service Architecture (MSA) instead of cloud computing:

 

Implementing MSA: One of the first critical decisions I made was to implement Multi-Service Architecture (MSA) across the engineering organization. Many people were initially resistant to this change, as it required a significant shift in the way we designed and developed our applications. However, by breaking down our applications into smaller, independent services, we were able to improve our development speed, increase scalability, and enable faster time-to-market for new features. This decision was ultimately appreciated by everyone, as it helped us to improve our overall efficiency and reduce development costs.

 

Investing in Containerization: Another critical decision I made was to invest in containerization for our services. Initially, some people were skeptical about moving our applications to containers, as they were used to monolithic architectures. However, by adopting containerization, we were able to improve our infrastructure efficiency, reduce maintenance costs, and increase the reliability of our applications. This decision was ultimately appreciated by everyone, including the CEO and CTO of the company, as it helped us to become more competitive and respond to changing business requirements faster.

 

Refactoring Legacy Code: A third critical decision I made was to invest in refactoring our legacy codebase to align with MSA. Many people were initially resistant to this change, as they felt that it would be a waste of time and resources to rewrite code that was already working. However, by refactoring our legacy code, we were able to align with the principles of MSA, make our systems more modular and maintainable, and reduce the risk of downtime caused by dependency on any one service. This decision was ultimately appreciated by everyone, as it helped us to avoid technical debt and ensure that our systems were up-to-date and competitive.

 

Overall, these decisions required a lot of courage, persistence, and vision. However, by taking these decisions, we were able to achieve significant improvements in our engineering organization and deliver greater value to our customers by adopting the latest technological advancements.
