Built and scaled a Node.js (TypeScript) conversational AI backend, integrating Azure AI Language and Microsoft Cognitive Services to process image/audio inputs and deliver speech-to-text / text-to-speech, including Flemish and Belgian Dutch language support.
Developed a Python serverless function (Azure Functions) using spaCy to process and analyze documents/text, enriching the bot with NLP outputs consumed by the platform.
Implemented robust input validation, control, and debugging using regular expressions, plus entity extraction (names, user responses, attributes) to improve data quality and NLP accuracy.
Delivered a React admin console to manage intents, utterances, flows, texts, and bot configuration, and added conversation summary features for both end users and agents.
Developed a .NET (Razor) operational screen and backend services backed by Redis caching, efficiently serving bot data produced by the Node.js platform.
Owned CI/CD and infrastructure-as-code (Azure Bicep), and drove the migration of the bot platform from OpenShift to Azure and Azure DevOps, improving deployment reliability and operational consistency.
