    I am an integration specialist who can connect different services! My main specialization is automation using Make (formerly Integromat) I have knowledge in: *Microsoft office products; *Webservices, API (RESTful); *SFTP, file management; *File transformation, structuring (XML, JSON); *HTTP(S) requests; Why do I specialize in Make? Because it is very easy to use, and maintain and you have full control of processes. Make has a very big variety of modules already implemented (like Calendly, Zoho, HubSpot, Xero, and more..) and in this way, I can get the job done very fast and in the best possible practice.
