Portrait of Fuad Efendi

Fuad Efendi, MSc

I’m the founder of Tokenizer Inc. and the publisher behind a portfolio of independent knowledge bases and exam-prep products. I hold an MSc in Mathematics from Moscow State University and began my career teaching quantitative subjects. Over the past 23 years, I’ve engineered financial systems—capital-markets data platforms, risk-modeling integration, and regulatory reporting—for major Canadian and U.S. banks. Today I combine math → software → teaching to build study tools that are practical, transparent, and aligned to official blueprints.

Biography

Teaching runs in my family. I taught mathematics, statistics, and quantitative methods before relocating to Canada and moving into software engineering. That transition reinforced a constant theme: reduce complex systems to first principles, then rebuild with transparent, verifiable steps.

Across banking/fintech I’ve worked on core financial systems, capital-markets data platforms, risk-modeling integration, and regulatory reporting. I’ve contributed to the Apache Solr/Lucene ecosystem and led teams on testing, observability, and performance at scale.

Mastery Exam Prep extends that approach to certification learning—clear explanations, runnable/interactive practice, and honest trade-offs anchored to official blueprints and primary sources, aligned to current outlines and regulator guidance (e.g., CIRO, FINRA/NASAA, AICPA, CFA Institute).
