Software Engineer
Worked on the payment API system, over a cluster of node servers, for Mytoddlr, an application that school teachers use to keep parents updated on their children's' daily progress.
Integrating a simple payment solution proved problematic, our business logic was complex, this meant working closely with the business team in the UK to build a system that worked for our unique use case (allowing payments from parents to nanny and school bank accounts).
Developed a dashboard to gather intelligence on how users used our mobile apps.
Built a robust Payment Platform that served our fast-growing 20,000 customers (parents and nannies).

Outcome: Increased payments (received) by 80%.
Increased monitoring of failed payment by 100%, because we could log those requests after the rebuild.
