Today marks a massive milestone in my tech journey. I am officially starting the #90DaysOfDevOps Challenge!

I firmly believe in the concept of "Learning in Public." By documenting my daily progress, configurations, and troubleshooting steps right here, I am holding myself accountable to build consistency and improve day by day. My goal is simple: to transform from an aspiring learner into a highly skilled DevOps Engineer.

🧑‍💻 About Me My name is Vansh Yadav. I am a Graduate student of Bachelor of Computer Applications (BCA) at Shri Shankaracharya Professional University.

Over the course of my degree, I've loved building things. I have some hands-on experience under my belt, including:

Developing an Expense Tracker Web Application using Spring Boot, Thymeleaf, MySQL, and Docker.

Creating an AI-based Smart Resume Classifier Project using Python, Natural Language Processing (NLP), and Streamlit.

Deploying applications using architectures like Nginx on standard AWS Free Tier setups.

While building these projects, I fell in love with automation, deployment, and infrastructure. That's exactly what brought me to the world of DevOps. I realized that writing code is only half the battle; knowing how to deliver it efficiently, securely, and reliably at scale is where the real magic happens.

🎯 Why the #90DaysOfDevOps Challenge? DevOps isn't just about learning a single tool; it’s a culture, a methodology, and a vast ecosystem. It can easily feel overwhelming.

I am taking this public challenge to:

Build Consistency: Forcing myself to learn, practice, and write every single day.

Bridge the Gap: Transitioning from basic application development to true cloud-native infrastructure automation.

Help the Community: I want this blog to serve as a practical, real-world handbook for anyone else starting out. If I run into an error and fix it, I will write the solution here so you don't have to struggle!

🗺️ My 90-Day Learning Roadmap To keep this journey structured, I have broken the next 90 days into dedicated technical phases:

🐧 Phase 1 (Days 1-15): Linux & Shell Scripting – Core OS fundamentals, file permissions, and automation scripting.

🌿 Phase 2 (Days 16-30): Git & GitHub Workflows – Version control mastery, branching strategies, and collaboration.

🐳 Phase 3 (Days 31-45): Containers & Microservices – Deep dive into Docker, custom images, volumes, and networking.

⚙️ Phase 4 (Days 46-60): CI/CD Automation – Building automated pipelines with Jenkins and GitHub Actions.

☁️ Phase 5 (Days 61-75): Infrastructure as Code (IaC) & Cloud – Provisioning resources on AWS using Terraform and configuration management with Ansible.

☸️ Phase 6 (Days 76-90): Container Orchestration – Managing production-grade clusters with Kubernetes, culminating in a comprehensive capstone deployment.

🚀 Let's Connect! I am incredibly excited to share everything I build and learn over the next three months. If you are a DevOps professional, a fellow student, or just curious about cloud engineering, let's connect and grow together!
