About Nicolas

Senior Infrastructure & Batch Operations Specialist with over 15 years of experience in Mainframe and Midrange environments, ensuring continuity of critical services in banking and regulated sectors. Proven expertise in incident management, batch ecosystem optimization, and strict SLA compliance, with a strong track record in resilience and continuous improvement.

I bring a hands-on approach, strong root cause analysis (RCA) capabilities, and experience with modern observability tools (Grafana, Dynatrace, Mainview, among others). My core value proposition is to guarantee stability, performance, and high availability in complex infrastructures, bridging traditional operational environments with modern technologies.

PurePlay is a local AI-based tool that turns real songs into practical material for music practice. It separates key elements like vocals and instruments, allowing users to isolate and study each part while keeping the original track intact. The system runs fully offline, ensuring control, privacy, and consistency.

I am particularly interested in international projects that require operational excellence, automation, system reliability, and practical AI integration — connecting legacy infrastructure with modern system design principles.
