Hey, I'm André

Security researcher, reverse engineer, and builder. I break things open to understand how they work, then build something better — and ship it.

What I do

Reverse engineering & security research — firmware cryptanalysis, ARM/DSP binary analysis, protocol reconstruction, and building emulators from the ground up. I crack proprietary systems and turn the findings into open-source tools.

Machine learning & quantitative finance — feature selection via block permutation importance, multi-objective gradient boosting, out-of-sample validation with statistical rigor (bootstrap CIs, effect sizes), and end-to-end backtesting infrastructure.

Systems programming — performance-critical C/C++, real-time audio DSP, JIT compilation, and low-level optimization on Linux.

Products & AI tooling — SaaS applications, API services, AI-powered developer tools, and business automation. From architecture to deployment.

Featured project

Zamphenom — the first open-source emulator that runs real Kemper Profiler firmware as a real-time VST plugin. Built solo in one month: cracked the firmware encryption, reverse-engineered both the ARM host and the Motorola DSP56720 signal processor, contributed fixes to an established open-source emulator engine, and wired it all into a DAW plugin.
