Led efforts to scale an energy trading platform called Joule Direct. A multi-tenant, SaaS platform designed to replace the previous generation of the trading software known as Trading Gateway, which was deployed per customer.
The work involved a lot of stress testing, covering the entire platform stack including networking and infrastructure. This resulted in my recommendation to use HAProxy which not only significantly reduced costs but also improved our ability to make changes faster. In doing this, I also introduced Grafana and Telegraf which helped us improve observability of the platform and finally gave us a better insight into key performance metrics such as tail latency and throughput.
From a development point of view, a lot of work was done to reduce contention in multi-threaded code, improve the reliability of timers, reduce memory allocations to lower garbage collection pauses and improve network throughput with batching.
