I recently decided to dive deep into the world of DevOps, and I want to take you along for the ride. If you’re curious about DevOps or just starting out too, this post might resonate with you — or even better, we can learn together!</p> <p>Right now, I'm still curating the best roadmap to follow and then start</p> <h4> 🧠 Why DevOps? </h4> <p>I come from a background in Robotics Process Automation, using tools like UiPath, Automation Anywhere, and Power Platform. I’ve always been drawn to systems that make work more efficient, automated, and scalable.</p> <p>Over time, I kept hearing the buzzwords: CI/CD, Docker, Kubernetes, Jenkins, Cloud, and so on... It felt overwhelming. But I also knew that behind all the jargon was a philosophy that made tech teams faster, stronger, and more reliable.</p> <h4> So I asked myself: </h4> <p>What if I give DevOps a real shot?<br> In the next few days, I will be sharing my DevOps journey here. I hope in the next few months or probably years, I'll look back on my DevOps journey and be happy I did.</p> <h4> <strong>💬 Let’s Connect!</strong> </h4> <p>Are you also starting with DevOps? Or are you further ahead and have some advice for me? Let’s chat in the comments — I’d love to hear your thoughts or book recommendations.</p> <p>✍️ <em>Feel free to connect with me on <a href="https://www.linkedin.com/in/oluwatimileyin" rel="noopener noreferrer">LinkedIn</a> or follow my journey here if you’d like to keep up with my DevOps series.
