GenAI Engineering Lead
Building production-ready GenAI systems with the evaluation rigor and operational discipline needed to ship GenAI that works reliably at scale. 9+ years in ML, including 3 years leading GenAI at a major European payment processor.
Background
9+ years building production ML systems, including 3 years leading GenAI initiatives at a major European payment processor.
My experience centers on bridging the gap between GenAI prototypes and production systems. This includes building evaluation frameworks to measure quality, implementing monitoring to catch issues early, and designing architectures that scale reliably under real-world usage.
At enterprise scale, I've shipped LLM systems processing thousands of daily cases in high-stakes financial services environments. This work required the evaluation rigor and operational discipline necessary for systems where failures have significant business impact.
This hands-on production experience has shaped my approach to building GenAI systems that operate reliably at scale.
Core Strengths
Production-grade engineering
Experience with architecture patterns proven at enterprise scale. Built evaluation frameworks to measure quality before shipping. Implemented monitoring and observability from day one across multiple production systems.
Battle-tested in high-stakes environments
Shipped RAG pipelines, agent workflows, and LLM applications at enterprise scale in financial services. Debugged production failures and learned the common pitfalls in real-world deployments.
End-to-end ownership
Full-stack capability from system design through production deployment. Deep understanding of AI/ML, backend systems, evaluation frameworks, and operations that enables delivering complete working systems.
Evaluation-first mindset
Strong foundation in rigorous evaluation methodology. Experience building test datasets, metrics frameworks, performance benchmarking systems, and continuous monitoring for production GenAI.
Areas of Expertise
Core technical capabilities in GenAI engineering, from building production systems to providing technical leadership.
Production GenAI Systems
End-to-end implementation of RAG pipelines, AI agents, semantic search, and intelligent workflows with comprehensive evaluation frameworks and operational monitoring.
Key capabilities:
- RAG systems with hybrid search and retrieval optimization
- AI agents with tool use and structured reasoning
- Evaluation frameworks (quality, latency, cost metrics)
- Production monitoring and observability
- Infrastructure and deployment automation
GenAI Engineering Leadership
Technical leadership for GenAI initiatives from architecture design to team enablement. Establishing technical direction, quality standards, and enabling teams to ship production systems.
Key capabilities:
- GenAI strategy and technical roadmap
- Architecture design and technical decisions
- Evaluation frameworks and quality standards
- Code reviews and technical mentorship
- Cross-functional collaboration
What I've Built
Production systems built in high-stakes financial services environments, where reliability and evaluation rigor are non-negotiable.
