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. It provides a JSON REST API and integrates with many external systems. I started as a CHS dev and later shifted to the web app's backend (rarely frontend). I spearheaded new features, refactorings, migrations with external teams, updates, new conventions across 4 teams, CI/CD for a new project, failover in production, new architecture needs and onboarding.
