Hello po,
I have some 26 years of experience in the telecommunications industry and previously worked for Globe. My expertise lies in systems and integrations (APis and complex integrations) much like yours and I have previously implemented similar systems for large companies like Globe (Spotify, HooQ, NetFlix, Disney, etc) SingTel and in Australia for Optus (Optus Cable, Optus TV).
I would like to discuss more with you in detail and can be reached on +63 908 412 2748 for further discussions.
Salamat po,
Stephen Lombard
