Data Analyst | Security & Compliance
My portfolio reflects a data-driven journey rooted in analytics, risk, and regulatory compliance. It starts with four years analyzing financial and business data, building dashboards, KPI frameworks, and credit risk models that support real decision-making, the analytical core of how I work.
That foundation now extends into security and GRC: identifying vulnerabilities, mapping controls, and translating regulatory requirements (DORA, GDPR, ISO 27001) into auditable, structured frameworks. I've also explored smart contract development in Solidity and Foundry as part of expanding my technical range into Web3 fundamentals.
The common thread across all of it is analytical precision applied to complex, structured problems, whether the structure is a P&L, a compliance framework, or a smart contract.
