AI/ML security, identity, cryptography, fraud, and platforms
AJIT GADDAM
I currently lead Fraud, AI & Trust Platforms at HealthEquity. Before that, I built security and fraud systems at Wells Fargo, Visa, Progressive, a startup of my own, and Google.
This is my personal index: work, inventions, writing, and small things I am building outside the job.
BUILD SIGNAL
CURRENTLY
Working on AI-native fraud defense, autonomous-system trust, and platforms where models can take action—not only make suggestions.

BUILDS
01 / IOS + IPADOS + MACOS
The family app I wanted when a child asked for one specific coloring page and school artwork kept turning into a paper pile. It makes, prints, scans, and keeps the work without ads or child accounts.
02 / MACOS + STORAGE INTELLIGENCE
The storage recovery app I needed when my own Mac had less than 1 GB free. It explains what is growing, puts the safest meaningful decision first, and proves what changed.
03 / FRAUD + VOICE AI
A voice agent designed to consume a scammer’s time without putting a real person or real personal information into the conversation.
AI / ML + AUTONOMOUS SYSTEMS
The through-line is turning frontier capability into systems that can survive adversaries, customers, and scale.
My path began in AI and robotics at Carnegie Mellon, with work connected to the DARPA Grand Challenge. Today the system is software: agents that need bounded authority, evidence, and accountability.
Research and inventions on untrustworthy models, behavioral signals, and adaptive defense treated machine learning as an attack surface before AI security became a category.
A decade building ML-driven cybersecurity products at Visa, followed by fraud and generative-AI platforms in banking and healthcare, kept models close to customers and operating risk.
I have built as a founder, inside global platforms, and outside the job—keeping the loop from problem through architecture, release, customer reality, and operation visible.
