I built Veecall as a real-time communication platform using Node.js, WebRTC, Redis, RabbitMQ, and MongoDB. It supported hundreds of simultaneous users, and I investigated bottlenecks across signalling, backend throughput, and hosting.
At IOXIS SARL, I developed C#/.NET and SQL Server functionality for internal applications, data processing, and reporting. At IP Performance / IPAfrica, I delivered PHP/Magento features and REST integrations, and worked on OpenSearch-backed product search and hosted services.
In independent work, I built an MQL5 trading engine and integrated it with Python transformer inference, then operated and evaluated the system on a Windows VPS. I also built web backends, API integrations, and a car-rental invoicing application.
