About this Gig

IMPORTANT!! PLEASE REACH OUT TO DISCUSS PROJECT VIABILITY AND DELIVERABLES BEFORE PLACING AN ORDER.


Need to understand an application, diagnose an error, or maintain software without source code?

I provide reverse engineering and debugging for Windows applications, Android APKs, and Java JAR files. Using static analysis and runtime evidence, I explain software behavior, identify problems, and assess practical fixes.


Services include:

  • EXE, DLL, APK, and JAR analysis
  • Windows API, file, and registry tracing
  • Crash, startup, and dependency troubleshooting
  • Software version and patch comparison
  • Network and USB communication analysis
  • Undocumented file formats and configurations
  • Targeted modifications, rebuilding, and repackaging
  • Python scripts for extraction and automation

I select the tools and techniques that best fit your project, including Ghidra, IDA, CFR, Python, and other specialized debugging and analysis tools. Depending on scope, delivery includes documented findings, reproduction steps, scripts, or tested modifications.

You receive clear updates, realistic expectations, and explanations you can act on.

Message me before ordering with your files, issue, and desired outcome.

    Very pleased with the service I received from Brian. He understood my request and sent the revised firmware files very quickly, and they worked as I hoped they would first time!

    I've worked with Brian multiple times now and each time he doesn't disappoint me. He understands his domain well and is great at communication. I like that he tells me about potential hurdles beforehand and doesn't overpromise. I'll definitely be buying from him again.
