CRISTIAN APARA
@cristianapara
Executive enterprise and data architecture leader modernizing SAP and cloud ecosystems into API-driven, secure platform architectures.
What I'm looking for
I’m a technology leader with 18+ years designing and operating enterprise architectures and data platforms for large-scale, regulated organizations. I specialize in connecting complex ecosystems (SAP S/4HANA, Azure, Databricks, IRIS InterSystems) and modernizing legacy systems into scalable, secure, API-first architectures.
In my current role as Head of Enterprise & Data Architecture at ACHS, I lead the enterprise and data architecture strategy for 500,000+ insured workers. I defined and implemented the enterprise architecture framework across 15+ mission-critical systems, designed API-first governance that reduced time-to-integration by 40%, led USD $8M+ CAPEX/OPEX management with ~25% YoY cloud spend optimization through FinOps, and improved core platform availability to 99.95% for 24/7 operations.
