D.L. Timmerman

DL Timmerman is an award-winning writer, indie filmmaker, martial artist, and battle-hardened investigator with over 20,000 hours in the trenches.

A licensed private investigator and certified OSINT professional, he currently serves as a OSINT Product Manager in software, transforming raw data into powerful SaaS intelligence platforms. For two decades he has hunted truth through the shadows — cracking major fraud cases, dismantling theft rings, and waging a relentless personal war to find his kidnapped daughter.

He writes like he fights: raw, relentless, and unflinching. His gritty first-person noir thrillers fuse elite martial arts with real world OSINT tradecraft. No fluff. No mercy. Just the brutal cost of chasing justice in a broken world.

Author of Vehemence, a superhero thriller manga, and Creed: For God & Country. Upcoming work: Building Blocks: A Practical Guide to OSINT Investigations booklet and Hidden Ledger, a future noir thriller.
