About me

Hi, I'm Yerodin, a Full Stack Developer with over three years of experience building scalable and efficient business systems.

I’ve worked on mission-critical platforms for HR and payroll, automating complex workflows and enabling multi-tenant deployments using Azure AD B2C — boosting productivity and scalability.

At Kedo Solutions, I developed robust backend services using NestJS and Clean Architecture to support 300% user growth, and delivered real-time dashboards that improved decision-making speed.

I also co-founded Quinti, a food delivery app with 5K+ downloads, built with Flutter and real-time geolocation — helping connect local businesses with remote customers.
