Good day!

I am interested in your vacancy. I have over 10 years of commercial experience in React / React Native, mainly with supporting and developing existing projects — I am used to carefully entering someone else's code, understanding the architecture, and not breaking what works.

Regarding the stack and tasks:
- RN (functional components, hooks, TypeScript), native modules, integration of REST/GraphQL API;
- performance and stability optimization, bug fixes, working with crashes;
- participation in task estimation and proposing technical solutions.

In terms of format — I am a sole proprietor, official contract without questions.

I am ready to discuss the scope of work, stack, and expectations regarding workload. If convenient, I can take a look at the repository. Expand

Good day!
I am a full-stack mobile/web developer with over two years of commercial experience working with React Native. During this time, I have created and released over 20 mobile applications on Google Play and Apple Store - from idea and architecture to release and support.

I have experience in:
- developing new features and supporting existing projects;
- integrating APIs and optimizing performance;
- working with someone else's code and making careful changes;
- estimating tasks and proposing technical solutions.

I have worked both in companies and as a freelancer, so I understand the importance of responsibility, meeting deadlines, and quality communication.

Collaboration through an official contract will definitely not be a problem!!

I would be happy to discuss the possibility of long-term cooperation and connect to the development of your application.

Sincerely, Andriy! Expand
