Book your React and React Native consulting session with senior developers and Core Contributors!


Do you often feel like it would be great to ask somebody else about a potential solution? To be able to jump straight to the code with another developer, pair-program on it and figure out what’s wrong? Worry not, Callstack got you covered.

We offer paid consulting services in the field of React and React Native development. The consultations will be held by our experienced senior React and React Native developers.

What do the React and React Native consultations look like?

The consultations last for 60 minutes, take place online (by video-chat), and can be booked online by Calendly. The calendar invite will include a link to a video call that you can use in order to jump on a consultation.

The price - 349 EUR - includes 1-hour video-chat consulting plus preparations for your questions.

The consultation process is divided into 5 steps:

  • Step 1. Book a consultation.
  • Step 2. Describe your problem, send us reference materials (screenshots, videos, code snippets).
  • Step 3. Our senior developers perform deep research and prepare solutions for your inquiry.
  • Step 4. If we were able to find any solving, we meet with you on a 1-hour video-call and present our findings. If not, we return the money.
  • Step 5. After video-chat, we send you the meeting notes via email.

Who are our consultants?

We are Callstack - the official Facebook partners on React Native and have been working on React and React Native projects for over 5 years with a wide range of clients - from large enterprises to startups. Besides delivering high-quality solutions for our clients, we also work on the development of React Native ecosystem by our Open Source projects.

The consultant will be appointed at Callstack's discretion based on the expertise required to resolve the submitted issue.

Now let’s meet our consultants!
