Roshan Justin

I build businesses and the technology behind them. Founder of AppTeky, a Flutter team-as-a-service company. Partner at Adoni Traders, an FMCG distribution business in Trivandrum. Before that — 4 years of engineering enterprise apps for government agencies and tech companies at Technopark. I operate where code meets commerce.

About

Who I am

Passionate about building innovative mobile applications and exploring the endless loop of technology. Driven to create Apple-competitive products.

My journey started with mastering OOP in C++, becoming proficient in Flutter and Dart, and exploring Swift for native iOS. I'm a tech enthusiast with 6+ years of Linux experience, and a startup consultant helping entrepreneurs navigate technical decisions. Three years building enterprise apps at Technopark, Trivandrum — for clients like KSRTC and Kerala Police — taught me what real-world software demands.

But I've always thought like a businessman, not just an engineer. In 2024 I founded AppTeky, giving companies a dedicated Flutter team without the cost of hiring in-house. As a partner at Adoni Traders, an FMCG distribution business in Trivandrum, I run real operations on the ground — delivery routes, credit cycles, supply relationships, and the market itself. That mix of code and commerce shapes how I build products, advise startups, and grow businesses.
