What I'm looking for

I am seeking a remote Data Analyst or Systems Support role in an innovative, collaborative company where I can apply analytics, automation and systems troubleshooting to drive digital transformation and process excellence.

I am a versatile Application Systems Support and Data Analyst with over 7 years of experience optimizing data systems and supporting mission-critical applications across financial services, logistics, and public administration. I specialize in SQL, Python (Pandas, NumPy), Tableau, Power BI and Excel to design and automate dashboards that drive strategic decision-making.

My work has improved transaction accuracy, payment traceability, and system availability through automation, monitoring, and API integrations; notable achievements include a 27% improvement in transaction accuracy and a 33% enhancement in payment traceability. I have hands-on experience with SWIFT MT message types, ISO 20022 translations, RMA controls and AML-related monitoring.
