Strong and weakness

My Weak Areas:

Advanced Networking in Kubernetes:
While I can work with basic network policies, ingress controllers, and load balancers, I am still working on mastering advanced networking concepts like service meshes (e.g., Istio).
Programming Skills Beyond Automation: My Python and shell scripting are strong for automation tasks, but my experience with developing more complex applications or advanced programming concepts could be improved.
Multi-Cloud Expertise: My experience is primarily focused on AWS. I am less familiar with Azure or GCP but am eager to upskill to support multi-cloud environments.

Strong Area:

CI/CD Pipelines: Proficient in designing, implementing, and maintaining CI/CD pipelines using tools like Jenkins, GitHub Actions, and Argo CD. This includes stages for testing, code analysis, security scanning, and deployments.
Containerization & Orchestration: Strong experience with Docker and Kubernetes, including creating Dockerfiles, Kubernetes YAML manifests, managing EKS clusters, and using tools like Trivy for container security.
Infrastructure Automation: Skilled in writing Ansible playbooks for configuration management and automating deployments across environments. Also adept at Terraform for infrastructure as code.
Cloud Services (AWS): Expertise in AWS, including EC2, S3, VPC, ELB, IAM, ECR, and Route 53. Can design highly available, fault-tolerant applications leveraging AWS services.
Monitoring & Alerting: Experienced in setting up monitoring with Prometheus and Grafana, as well as AWS CloudWatch for alerts and log management.
Problem-Solving: Strong analytical skills in troubleshooting issues like failed deployments, Kubernetes node upgrades, and resource allocation challenges.

Hobbies

Example Answer for Hobbies:

“I enjoy exploring new technologies and experimenting with tools in my personal lab environment. For instance, I recently set up a Kubernetes cluster at home to better understand advanced configurations.

On a more personal level, I enjoy playing team sports like cricket or football, as they help me unwind and improve my teamwork skills, which I find valuable even in a professional setting.”

How You are updating yourself with new technology ?

“I make it a priority to stay current with the rapidly evolving technology landscape, especially in the DevOps field. Here’s how I do it:

Online Resources: I follow leading platforms like Medium, DevOps.com, and the AWS Blog to stay informed about new tools, trends, and best practices.
Learning Platforms: I regularly take courses on platforms like Udemy, Coursera, and Pluralsight to deepen my understanding of new technologies.
Hands-On Practice: I have a personal lab setup where I experiment with tools and concepts I encounter, such as exploring advanced Kubernetes features or trying out new CI/CD tools.
Community Engagement: I participate in DevOps-focused webinars, tech meetups, and conferences, where I learn from industry experts and exchange ideas with peers.
Certification and Training: I pursue certifications in areas relevant to my role, like AWS and Kubernetes, which help me stay structured in my learning.
Collaboration: I engage with colleagues and teams to discuss innovative approaches and share knowledge, which broadens my perspective on how to solve problems.

One thing you hate most in devops ?

“One thing I dislike the most in DevOps is handling repetitive manual tasks that could be automated but aren’t due to time constraints or organizational priorities. While automation is a core principle of DevOps, sometimes immediate deadlines force us to handle things manually, which can feel inefficient. I always try to find time later to automate such processes and make them smoother for the future.”

What is the toughest challenge you faced in your career ?

One of the toughest challenges I faced was with the “ibis” microservice , which is critical for automating infrastructure tasks. Oneday , the ibis service unexpectedly failed after a routine configuration update. This caused automation workflows to halt, impacting multiple dependent systems. The issue was critical, as it disrupted ongoing operations and escalated to senior management.

During troubleshooting, I discovered that the Raptor service was failing due to a conflict between the updated configuration and the external database it was using. Specifically, the logs indicated an error: Database connection timeout: failed to retrieve metadata. This pointed to an issue with the database connection parameters.

Steps to Resolve:

Log Analysis: I first reviewed the logs using monitoring dashboard and CLI tools. The logs showed that the ibis service was attempting to connect to a database endpoint using an outdated TLS version due to a mismatch in the security settings introduced by the update.
Rollback Attempt: I attempted to roll back the configuration changes, but the rollback failed because the service had already partially applied the new settings, making the older configuration incompatible.
Root Cause Identification: I traced the issue to a misconfigured TLS version in the Raptor microservice’s configuration file (raptor-config.yaml). The service was set to use TLS 1.1, while the database endpoint required TLS 1.2.
Reconfiguration:
- I updated the raptor-config.yaml file to enforce TLS 1.2 under the database.connection.security section.
- I also adjusted the database connection pool parameters (maxPoolSize and connectionTimeout) to handle high request loads better, as the default values were insufficient for peak operations.
Service Restart and Validation:
- I restarted the Raptor service using the CLI (systemctl restart raptor).
- I ran a series of automated health checks and manually triggered a few automation tasks to validate the fix.
Database Performance Optimization: To ensure stability, I also applied a performance tuning update to the database, optimizing query execution plans and clearing connection locks.

What is devops ?

DevOps is a set of practices that combines software development (Dev) and IT operations (Ops) to improve collaboration, automate processes, and enhance software delivery. It emphasizes continuous integration (CI), continuous delivery/deployment (CD), infrastructure as code (IaC), and monitoring. The goal is to deliver high-quality software quickly and efficiently.

Benefits of DevOps:

Faster Time to Market: Accelerates the delivery of new features and updates.
Improved Quality: Enhances software quality through automated testing and continuous integration.
Increased Efficiency: Reduces manual tasks and increases productivity through automation.
Better Collaboration: Fosters a culture of collaboration and shared responsibility.
Enhanced Reliability: Improves system reliability and uptime through continuous monitoring and automated deployment.

Introduction:

–> I completed my engineering from BPUT in 2018 and started my career at Blackknight in 2020 as fresher
–> Later In 2022, I joined HCL Tech
–> I have overall 4 years of experience in devops and cloud.
–> I Worked for various tools for build and release engineering, even automation and orchestration

–> To create infrastructure for environment like dev, QA, stage and production
–> Building CICD pipeline, so in my project we used Jenkins and GitHub as ci tool
–> writing the dockerfile for creating images.
–> writing Kubernetes YAML file for the deployment
–> Debugging the application if in case of any issues
–> Monitoring the entire Application
–> we are using the ansible for downloading and updating multiple dependencies in the host machines at the same time

Coming to the AWS cloud part
–> I have good knowledge in EC2, Storage, IAM, S3, VPC, ELB, EKS, SNS, Route53 services in AWS.
