Acerca de Sergio
Who I am
I am a Freelance GenAI Consultant with 8+ years in ML, including 2.5+ years leading GenAI at a major European payment processor.
I build production-ready GenAI systems for startups and scale-ups, with the evaluation rigor and operational discipline needed to ship GenAI reliably at scale.
Most companies can build a proof of concept. Few get it to production without wasting months or shipping systems that break. I bring production discipline from enterprise experience to help startups ship fast while building robust systems.
What I bring
- Production-grade engineering: Architectures proven at enterprise scale, with evaluation, monitoring, and observability built in.
- Battle-tested experience: RAG pipelines, agent workflows, and LLM applications in high-stakes industries.
- End-to-end capability: From design through deployment, delivering complete working systems.
- Evaluation-first: Rigorous methodology, test datasets, metrics, and continuous monitoring.
Typical projects
- GenAI Product Development: RAG systems, AI agents, semantic search, intelligent workflows, content generation.
- Fractional Engineering Leadership: Technical roadmap, architecture, team enablement, quality standards.
- Production infrastructure: Deployment, evaluation frameworks, monitoring, cost control.
Selected experience
- Owned delivery of production GenAI systems at enterprise scale supporting global operations: ticket routing, summarization, semantic retrieval, chatbots, QA, and AI-assisted KYC/AML workflows.
- Designed and deployed production ML systems with monitoring, retraining, and explainability across fintech, real estate and telecom.
How I engage
- Senior individual contributor or fractional technical lead.
- Mid-term engagements (3+ months).
- Remote-first, EU-based projects.
- Ownership from problem framing through delivery.
I work with startups and scale-ups that understand getting production GenAI right the first time is cheaper than rebuilding later.
