Mobile AppSec / RASP / iOS & Android

Milton Leslie
Senior Mobile Application Security Engineer
iOS & Android Hardening • RASP

I specialize in securing mobile applications operating in adversarial and high-risk environments. My work focuses on protecting iOS and Android apps against reverse engineering, runtime attacks, tampering, and unauthorized manipulation — particularly in fintech and regulated contexts.

Threat model first. Runtime matters. Assume compromise.

What I Do

Experience Snapshot

I currently work on mobile security solutions focused on application hardening and runtime protection, contributing to platforms designed to prevent reverse engineering and active exploitation.

My background includes more than a decade building and securing systems for financial institutions, including international money transfer platforms, banking integrations, and mobile applications operating under regulatory pressure.

Security Mindset

I design mobile systems under the assumption that the attacker has full access to the device, can intercept traffic, manipulate runtime behavior, and analyze binaries offline.

Security decisions are driven by realistic threat models, not by checklists. Defensive measures are applied where they meaningfully reduce attack surface and increase exploitation cost.

Zero trust on client-side. Defense-in-depth. Runtime-aware.
