At Hotline Internet and Technology Co., I developed and maintained vCommers, a B2B/B2C commerce platform, and built APIs, AI-powered features, enterprise search, and real-time services. I also managed multi-cloud deployments and CI/CD pipelines, and led a team of 8 developers.
I integrated OpenAI APIs into vCommers for automated product content generation and developed an enterprise search platform using Apache Solr and Solarium PHP. My work also includes real-time notification services with Node.js and Socket.IO, and visual search APIs using Pixolution and Flask.
