Project history
Lead data architecture and AI strategy engagements for enterprise clients. Design end-to-end data pipelines and GenAI solutions on GCP and AWS, from data readiness assessment through architecture to delivery. Collaborate directly with client stakeholders and translate business requirements into data engineering and architectural solutions. Advise on data modeling, pipeline design, and cloud platform selection.
Conformly AI develops tools for AI-powered compliance analysis in automotive safety engineering, supporting standards including ISO 26262, ASPICE, and ISO/SAE 21434. Designed and built the compliance-analysis backend end to end including document ingestion, retrieval, and an LLM evaluation engine. Diagnosed and fixed a production defect reducing unparseable evaluator responses from 32% to 3.6%. Established the evaluation and governance framework including pre-registered experiment cards, Inspect AI harness, bootstrap confidence intervals, and data governance per EU AI Act and ISO/PAS 8800. Built the model-adaptation programme with a 4,615-document synthetic corpus and a 90-run LoRA grid on Axolotl. Secured and delivered a EuroHPC allocation on MareNostrum 5 (100,000 CPU-hours).
Designed and developed software and data systems, and modeled databases and computational systems. Engineered data systems, applied ML techniques, and developed GenAI solutions. Built and maintained Databricks and Snowflake pipelines in PySpark, including streaming and real-time processing on Databricks and GCP. Designed, implemented, and managed infrastructure across GCP, AWS, and Azure.
