Designing systems that scale with your business.
I help organizations turn their technical complexity into a competitive advantage — through clear architecture, pragmatic decisions, and full ownership of the outcome.
Areas of Expertise
Comprehensive IT consultancy services across multiple domains
Strategic IT planning, system integration, and technology roadmapping. Systems Architecture serves as the foundation that connects and aligns all IT domains to business objectives.
AWS architecture, infrastructure-as-code, and DevOps practices that make platforms reliable and teams autonomous
Scalable data platforms and pipelines that turn raw data into business intelligence — from ingestion to analytics
Framework-driven security posture embedded at the architecture level — not bolted on after
Translating business needs into technical requirements — bridging stakeholders and engineering to solve the right problem
Bridging Technology
& Business Strategy
I'm Nicolas Surleraux, a Cloud & Data Architect with 8 years of experience in regulated industries and B2B products. I design and industrialize AWS and Databricks platforms under real constraints — from secure infrastructure (NIST, SCPs) to production data pipelines.
Comfortable owning the full technical scope across architecture, data engineering, cybersecurity, and DevOps — and translating that into business outcomes that matter.
