Jasurbek Umarov 👋

Full Stack Developer. I build modern web and mobile apps with Next.js, React Native, TypeScript and NestJS.

My work experience

At Basaltium, BIKO, AIKO and SoftTurtkul, I built internal automation systems, e-commerce websites and mobile apps. I can bring the same experience to your project.
