Hi, I'm Jaohar Raihan

I'm a focused and passionate Software Developer who builds cross-platform mobile apps using React Native (CLI & Expo). React Native is my main skill, but I also enjoy working on different parts of software—from web development to integrating AI models into all kinds of services.

About Me

I come from Sandwip, a quiet island in Chittagong where life feels calm and people truly care for one another. Growing up there, I was surrounded by love, support, and a strong sense of community. It's a place I'll always be proud to call home. My family means everything to me. They've always stood beside me, and their love gives me strength. I also deeply value the people who take a little time from their lives to talk with me. Even a short conversation can mean a lot.

I'm proud to say that I'm Bangladeshi 🇧🇩. In my teenage years, I spent hours watching sports and cheering for my heroes. Shakib Al Hasan and Leo Messi have inspired me for years. After Messi, Neymar became a favorite, and in cricket, I've always admired Mashrafe Bin Mortaza. Their journeys taught me about passion, discipline, and staying true to yourself.

Now, I build apps using React Native. I try to learn something new every day — not only from writing code but also from life and from the people around me. I'm still learning, still growing, and always thankful for the people and places that shaped who I am.
