THE JOURNEY

Experience

Leading consulting engagements across AI platform engineering, cloud-native data systems, and public sector digital transformation.

  • Generative AI Platform for Enterprise Data Access: Designed and implemented a multi-agent GenAI application that streamlines access to enterprise data through natural language queries. The platform integrates multiple agents (PDF parsing, BigQuery search, routing logic) within a unified GCP-based architecture using Vertex AI and Streamlit.
  • Cloud-Native SDMX Data Platform for Public Sector Reporting: Developed a secure, cloud-hosted solution for acquiring, transforming, and publishing statistical data in SDMX format. The system ingests semi-structured files (PDFs, XLSX) and converts them into ready-to-publish datasets using generative AI and metadata-driven workflows on Azure and GCP.
  • Sustainability Intelligence with AI-Powered Classification: Built a document classification pipeline using Retrieval-Augmented Generation (RAG) to assess environmental reports. Applied confidence-based scoring to classify topics and determine coverage and criticality levels for ESG evaluation.
  • Enterprise Training and AI Enablement: Serve as an instructor and consultant for organizations adopting AI and cloud. Deliver tailored training sessions in Azure, GCP, AI fundamentals, document intelligence, and containerized app deployment.

Delivered data engineering and ML solutions for banking and retail clients across European markets.

  • Data Platform and Data Exchange API for a Central Bank: Engineered and implemented a robust and secure data platform along with a data exchange API for a central bank in Europe. Integrated data from multiple SDMX data providers ensuring comprehensive data collection with strong regulatory compliance.
  • Demand Forecasting and Replenishment Strategy: Contributed to the implementation of a machine learning-based demand forecasting system for a major retail client. Assisted in designing a replenishment strategy using real-time sales data and seasonal trends to improve inventory management and supply chain efficiency.

Leading development of a modular geoscientific visualization and analysis platform combining scientific computing with modern cloud infrastructure.

  • Interactive Geoscientific Visualization Platform: Designed and developed a modular web application for visualizing and analyzing geotechnical datasets. The platform supports real-time interaction with point cloud data, discontinuity mappings, and stereographic projections.
  • 3D Grid Classification & Stereographic Workflow: Built a custom interface to display geological cube classifications by z-level, enabling users to select spatial regions via interactive, image-backed buttons. Developed an intuitive overlay and grouping system for domain experts.
  • Cloud-Native File Ingestion & Scalable Deployment: Implemented secure, chunked file uploads to Google Cloud Storage, optimized for large scientific files. Managed containerized deployment using Docker and NGINX, with migration plan toward Kubernetes (GKE) for production scalability.
  • Monitoring and Observability: Engineered a lightweight monitoring service to track Docker container health and resource usage. Designed automated alerts with HTML email reports and integrated loguru-based diagnostics for production environments.
