About this gig

Need a web app, website, or Android/multiplatform app built or fixed? I'm a full-stack developer working with React, Next.js, and Kotlin/Jetpack Compose, and I can help whether you need something built from scratch or an existing app fixed and improved.

What I can help with:

  • Building web apps and websites with React & Next.js
  • Building native Android or multiplatform apps with Kotlin & Jetpack Compose
  • Fixing bugs, crashes, or broken features in an existing app
  • Clean, well-structured, documented code not just something that works once

I also have real-world experience with CI/CD (Jenkins, Docker, GitHub Actions), so if your project needs a reliable build/release setup, I can help there too.

Not sure which package fits your project? Send me a message before ordering and I'll help you figure out the right scope.
