Projects
Self-Hosted AI & Knowledge Systems Architecture
Design and deployment of a production-grade, fully self-hosted AI assistant within a secure national infrastructure.
The system leverages Retrieval-Augmented Generation (RAG) to deliver precise, knowledge-base-grounded guidance across digital health platforms, identity systems, and health information ecosystems.
Architectural emphasis included secure inference pipelines, high-concurrency model serving, controlled knowledge retrieval, and strict institutional response constraints.
Digital Health Platforms & Interoperability
Design and operationalization of interoperability-aware digital health systems, including large-scale deployments of national health information platforms.
Work involved metadata harmonization, standards alignment, system integration strategies, and the development of middleware architectures enabling structured data exchange.
Identity & Access Architecture
Deployment and integration of federated authentication frameworks supporting secure access across distributed digital platforms.
Focus areas included trust models, identity governance, and secure gateway design within institutional environments.
Email Infrastructure & Security Systems
Design and deployment of enterprise-grade email infrastructure and security mechanisms, including domain authentication, reporting analytics, and operational monitoring systems.
Includes development of specialized tools such as DMARC analysis dashboards and administrative plugins.
Health Data & Terminology Systems
Technical contributions to classification systems, metadata dictionaries, terminology governance, and standards-driven data structures supporting national health information ecosystems.
Infrastructure & Virtualization Engineering
Design and management of virtualization environments, infrastructure resilience strategies, and system performance optimization across distributed services.
