A Master's graduate in Computer Science with strong experience in backend engineering, AI systems, and data platforms. I build scalable, high-performance systems for AI-driven applications.

Currently at Rackspace Technology, I design multimodal AI pipelines (OCR + LLM) for document processing and lead GraphQL API development for enterprise data platforms on Azure Cloud.

Previously at VNG Corporation, I built big data platform APIs, managed Kubernetes infrastructure, and developed React/Electron desktop applications for data engineering teams.
