Software Engineer
Celfocus - Unified Communications - One Net
Aug. '19 - Feb '23
Tech: Java (JBoss, Spring, Hibernate), React, PostgreSQL, ActiveMQ; Docker, Bash, Gitlab CI (K8s on GCloud), Helm, Terraform
One Net is Celfocus's enterprise voice solution with 5 international deployments. The Call Handling Server (CHS) is a 190k SLOC C++ backend with an in-memory DB (no ORM). It speaks telco protocols (SS7 and SIP) and so has strict SLAs. Its database is provisioned via a web app written in React and Java. I did both CHS and backend development (rarely frontend): new features, refactorings, failover in production and new architecture needs.
