Top SchoolMarcio Castillo is an Information Technology Specialist and cybersecurity-focused IAM engineer with 11 years of experience building secure, automated IT services for public-sector environments in New York. At NYSIF he combines ServiceNow development, Azure DevOps administration, and change management to deliver auditable CI/CD pipelines and identity lifecycle automation. He pairs hands-on scripting (JavaScript, Python, Bash) and automation tools like Ansible and Omada with a practical security posture to reduce risk across access controls and deployments. Outside work he is an active open-source Bitcoin developer, running full nodes, building wallets, and contributing privacy- and security-focused tooling for regtest/testnet environments. That crossover between enterprise identity controls and self-hosted cryptocurrency infrastructure gives him a unique perspective on secure, user-centric system design.
