    I offer full-stack flutter development having 4 years of development experience. I can integrate mobile apps with your backend services APIs or adjust existing ones written with NodeJS (JS/TS): Express, NestJS, Fastify + SQL/NoSQL database, or Firebase/Google Cloud sets of services. Additionally, I’m up to learning specific products if it’s necessary for you to integrate them and develop a solution to your problem. I can debug, refactor and solve other issues in existing flutter applications (for example, null-safety migration) and add new features you need. I have successfully developed and released several Android/iOS apps to stores and managed their life cycles. Feel free to contact me if the description doesn’t entirely meet your needs, as I'm open to new opportunities, and I’m happy to help you build the product you want.
