Sfxdx employs a team of specialists that have expansive knowledge and experience in solution based development across the full spectrum of innovative development needs of the client.

Our large-scale project was fully integrated with blockchain, tokenomics, smart contracts, frontend and backend developments. In each area, Sfxdx worked in a consistent manner of excellence while paying close attention to detail and achieving a meaningful solution to create the reality.

- 1 blockchain developer
- 3 backend developers
- 3 frontend developers
- 1 devops
- 1 tester
- 1 project manager
- 1 sales manager

Professional communication, straight forward dialogue, and detailed Project Management were all present throughout our experience with Sfxdx - and we will be using this excellent group of highly intelligent developers again in the near future!
