Oleksii Popov

Expert Software developer at TomTom
Amsterdam, Netherlands
I speak English, Ukrainian, Russian, Dutch (A2)


I am a skilled software developer with 11 years of experience in web technologies. I am passionate about developing user-friendly products and have a track record of designing and implementing full-stack solutions, combining frontend, cloud native, and backend areas. My expertise lies in the architecture and development of high-scale single page applications, UI libraries, and SDKs, as well as in the implementation of CI/CD, hosting, and distribution solutions.

I am proficient in TypeScript and JavaScript across all stacks and use them whenever possible. However, I am also experienced in maintaining projects in other languages such as Java and PHP.

I am enthusiastic about optimizing applications for improved runtime and faster loading speeds, both for existing projects and new ones.

I am looking for an opportunity to build a distributed, remote, asynchronous, and self-sufficient team around an exciting project.
