About the Founder

A complete reinvention arc.

I have 15+ years of experience in technology — and my career has been a deliberate, end-to-end reinvention. I started in core banking and mainframe development, moved into data engineering and test automation, built frameworks and pipelines across banking, fintech, energy, and e-commerce in both India and Luxembourg, and have now moved fully into cybersecurity governance, risk, and compliance.

Every phase added something the next one needed. The development years gave me systems thinking. The automation years gave me precision and process discipline. The GRC turn is where all of it came together — and where I found the work that actually interests me most.

This platform exists because I know what it feels like to restart, rebuild, and learn fast under pressure. The content here is built from real study cycles, real mistakes, and real exam reasoning. Some content is published under the persona #AnyaInCyberSecurity — my voice for breaking complex topics into clear, exam-ready thinking. The work and responsibility behind it is entirely mine.

01
Core banking & development
Started in mainframe COBOL and core banking — where systems thinking and precision under constraints became second nature.
02
Data, automation & architecture
Built test automation frameworks and data pipelines across fintech, energy, open banking, and e-commerce in India and Luxembourg.
03
European financial sector
Worked across EIB, LuxHub, CREOS, and Julius Baer — gaining deep exposure to regulated environments, PSD2, and institutional risk.
04
Cybersecurity GRC
Now focused on governance, risk, and compliance — exam preparation, GRC case studies, and practical security thinking for practitioners.
