Summary
👤
Senior🎓
Top SchoolNicolas Schirmer is a Principal AppSec Mobile Security Lead based in São Paulo with over a decade designing and hardening mobile platforms for high-risk environments, currently leading iFood’s mobile AppSec team with a purple-team approach. He combines deep low-level expertise (assembly, kernel, NDK/NDK drivers, reverse engineering) with cloud and DevSecOps practice to build SDKs, RASP integrations, threat intelligence pipelines and automated security tooling. His background spans product-focused security architecture, fraud prevention and bespoke research projects—from a unique device fingerprinting SDK to an Android app intentionally full of vulnerabilities used for training and CTFs. Nicolas has a track record of turning research prototypes into production features (Motorola code-offloading and ML battery prediction) and shipping integrations that bridge security, developer experience and incident tooling. Known for curiosity-driven problem solving, he brings both hands-on pentest skills and systems-level thinking to mentor teams and reduce real-world risk.
