Operations professional with 4+ years in back-office operations, transaction processing, and financial workflow management — transitioning into Security GRC and risk analysis. My day-to-day centers on the disciplines GRC roles run on: defect resolution, root-cause analysis, incident escalation, internal controls, and audit-ready documentation.

I hold a BSc in Computer Science, am completing an MSc in Economics & Finance, and have completed foundational training in Web3 security through Cyfrin Updraft and Harvard's CS50 Cybersecurity. Currently pursuing CompTIA Security+ and Microsoft SC-900.

Strengths

What I Bring to a Team

📋

Operations & Incident Handling

Four years managing transaction processing, defect resolution, and incident escalation in zero-error-tolerance environments — the daily muscle that GRC and risk-analyst roles run on.

🔍

Root-Cause Analysis

First point of contact for complex operational defects — running root-cause investigations, implementing corrective controls, and producing post-incident documentation across multiple teams and systems.

📄

Process Documentation & Internal Controls

Author of BRDs, SOPs, and process maps that support audit readiness, internal control standards, and operational accountability — the documentation discipline GRC roles rely on.

🎓

Computer Science Foundations

BSc in Computer Science providing the technical literacy to talk to engineers, read documentation, and understand the systems behind the controls I'm asked to enforce.

💹

Financial & Economic Literacy

MSc in Economics & Finance in progress — econometrics, financial market analysis, macroeconomics, international commercial law — relevant to fraud analysis, AML-adjacent work, and financial-risk operations.

⛓️

Web3 & Blockchain Foundations

Completed Cyfrin Updraft's Smart Contract Engineer & Security Researcher track — Solidity, Blockchain Basics, Wallet Security, and Zero-Knowledge Proofs — building foundational vocabulary for Web3-adjacent security and risk work.
