Dynamic Data Engineer | Data Analyst - I Help Founders Track What Matters & Make Smart Decisions. I have a proven track record of implementing innovative systems that boosted report accuracy by 25% in high-pressure projects by leveraging automation tools — such as VBA, Python, SQL and Power Automate — and employing advanced data visualization skills using PowerBI and Excel. What I have learned along this journey is that leading a high-performance team requires more than a reactive approach. Instead of putting out fires, I believe in precise error identification and the promotion of structured solutions; asking - “What can I do to ensure they don’t make this mistake again?” - is essential for continuously optimizing processes, whether through a framework review or small strategic adjustments.

I have a strong background in deciphering highly encrypted and obfuscated software systems and am a self-taught enthusiast for reverse engineering. Understanding and navigating intricate software protection layers using a combination of low-level analysis, perseverance, and systematic problem-solving is my area of expertise. I've gained practical experience using cutting-edge security measures over the years, such as: Obsidium, VMProtect, and Themida (anti-tampering, anti-debugging, and virtualization); heavy code obfuscation and binary encryption; implementations of custom virtual machines and multi-layer packing. I can analyze binaries both statically and dynamically thanks to my proficiency with programs like x64dbg, IDA Pro, Ghidra, and others. In order to understand underlying structures, I frequently reverse-engineer logic, circumvent layered protections, and analyze application behavior at the assembly level.
