Jun 2021 – Jan 2022

Nairobi, Kenya

Built the payments backbone for a streaming platform serving Africa and its diaspora. A Spring Boot microservice bolted onto a legacy PHP backend cut transaction issues by 40%, and the Android casting feature I led lifted engagement while slashing cross-platform drop-off. Dockerised the lot and shipped it on Linode.
