About Me
Hello, I'm Mithlesh Kumar
I'm a Full-Stack Software Developer (SDE-2) with 5 years of experience building scalable web applications that solve complex problems. Currently working remotely at eKincare, I specialize in Ruby on Rails and React, creating healthcare solutions that impact over 800,000 users.
"I love solving complex tasks and building scalable applications that make a real difference in people's lives."
My Journey into Programming
I've always been a geek at heart, and computers fascinated me from an early age. That curiosity led me to think, "Why not give programming a try?" So I did, and I haven't looked back since.
I started my development journey in January 2021 with a formal education — a Bachelor's degree in Computer Science. Over the past 5 years, I've grown from a curious beginner to an SDE-2, working on production systems that serve hundreds of thousands of users.

What Drives Me
I'm passionate about architecting scalable systems and leading technical initiatives that deliver measurable business impact. I thrive when designing solutions that serve hundreds of thousands of users, mentoring development teams, and driving technical excellence through architecture reviews and best practices.
My experience includes architecting systems for 800K+ users, leading cross-functional projects, and driving technical decisions that balance scalability, performance, and maintainability. I'm ready for Senior Engineering (SDE-3) roles where I can take on greater architectural ownership, lead development teams, and shape the technical direction of impactful products.
Beyond Code
When I'm not coding, you'll find me:

Swimming — Staying active and clearing my mind -
Reading about tech — Keeping up with the latest in software development, architecture, and best practices
Why This Blog?
I'm starting this blog to keep a record of my personal learning and growth. It's a space where I can document new technologies I explore, challenges I overcome, and insights I gain along my journey as a developer.
Years from now, I want to be able to look back and see how much I've grown — and hopefully, my experiences can help other developers on their own journeys too.
