About Me

Hey there! 👋 I'm a software engineer who loves turning complex problems into elegant solutions. When I'm not coding, you'll find me exploring new tech, diving into astronomy, or mastering the art of the perfect power nap.

I believe in building software that makes a real difference in people's lives. Whether it's creating intuitive user experiences or solving tricky technical challenges, I'm all about making things work better.

🚀 Current Adventure

Leading Android projects at Mercari, where I get to impact millions of users daily while working with some of the most talented engineers from around the world

💡 My Superpower

I'm a bridge-builder—connecting different technologies, teams, and cultures. My diverse experience across mobile, web, and backend makes me a versatile problem-solver who thrives in collaborative environments

🌍 Global Perspective

From Indian tech hubs to international innovative ecosystems, I bring a unique global perspective to software development, understanding how technology can transcend cultural boundaries

"If I don't know something, doesn't matter, I am damn good at figuring things out"
— My approach to problem-solving

🌏 My Journey: From College Dreams to Global Reality

Every great journey starts with a single step. Mine began in the classrooms of IIIT Gwalior and led me across continents to the global tech scene. Here's the story of how a curious CS student became an international software engineer:

🎓

The Foundation Years

July 2019 - July 2023 - Started my Computer Science journey at IIIT Gwalior. Late-night coding sessions, competitive programming contests, and the thrill of turning caffeine into code. This is where I fell in love with algorithms and discovered my passion for building things that matter.

🚀

First Taste of Real World

September 2021 - Landed my first internship at Trell! Working remotely on a platform with 10M+ users was mind-blowing. I learned that great code isn't just about logic—it's about impact. Reduced customer support queries by 15% and realized I could actually make a difference.

🔬

Research & Innovation

May 2022 - Dove into the world of research at Samsung Research Institute. Network packet analysis and SSID identification algorithms—definitely not your typical college project! This taught me that engineering is as much about curiosity as it is about coding.

🛠️

Building from Scratch

December 2022 - Back to Inito as a backend intern, but this time architecting microservices from the ground up. JWT authentication, service registries, 300+ unit tests—I was becoming a true backend engineer. The healthcare impact made every line of code meaningful.

💼

First Full-Time Role

June 2023 - Promoted to full-time Software Engineer at Inito! From intern to engineer, I was now handling data pipelines, Ruby on Rails development, and AWS deployments. The confidence boost was real—I wasn't just learning anymore, I was leading.

🛫

The Tokyo Leap

November 2023 - Packed my life into two suitcases and flew to Tokyo to join Mercari! The excitement was overwhelming, the adaptation real, but the adventure had just begun. From familiar tech parks to Tokyo's international corporate environment—what a transformation!

🍜

Cultural Adaptation

First Month in Tokyo - From mastering new work cultures to understanding international business etiquette, every day was a learning experience. Discovering that great engineering principles are universal, but communication styles vary beautifully across cultures.

📱

Android Excellence

Ongoing - Now leading core Android projects at Mercari in Tokyo, impacting millions of users globally. Working with Kotlin, Jetpack Compose, and an incredible international team. Every commit feels like contributing to the future of digital commerce.

🌸

Finding My Rhythm

Present Day - Tokyo feels like home, but India remains in my heart. I've learned that great software transcends borders, and great teamwork is about understanding and respecting different perspectives. Home isn't just a place—it's where you grow, contribute, and find your community.
