Portrait of Peter Leonard Paul Asirvatham

Peter Leonard Paul Asirvatham

I am someone who seeks to live with purpose, aligning my life with God’s plan and desire is to be salt and light wherever I go. Through my journey, I hope to encourage others to walk in faith and purpose, to bear fruit that lasts, and to stay faithful in every season.

I was born and raised in a small village in South Tamil Nadu, India. My world was simple, but filled with curiosity. During my school days, I was fascinated by computer games like Ball & Paddle, Dave, and Bricks. What began as a love for gaming soon grew into a desire to understand how these games were created.

That curiosity led me toward programming. Most of my academic projects ended up being game related, including my own version of Ball & Paddle, the project that sparked my passion for coding.

Today, when I look back—from playing games in a small village to being part of the tech world, I am filled with gratitude. His guidance has led me through every step, and I remain committed to learning, building, and walking faithfully in the purpose He has given me.
