As an experienced and multi-skilled developer for over 10 years, I understand the ins and outs of your project needs. Though my expertise lies largely in MQL4 and MQL5, my background in the trading-view using Pine Script, Trade Station using Easy language, Ninja trader, JForex, Amibroker, ProRealTime, aligns perfectly with your requisites. At the crux of it all are my programming languages: C++, C, Java, VBA, MQL4/5 demonstrating vast knowledge in reverse engineering -- essential for deobfuscation and conversion tasks proposed in your project.
Additionally, I recognize the importance of clear communication throughout project timeframes and my tendency to provide quick answers to technical queries further ensures streamlined operations. My proficiency with dnSpy/ILSpy and their likes would be invaluable for successfully deobfuscating your DLL while ensuring that the organized code is stripped of all obfuscation artifacts.
Ultimately, choosing me means not just getting your deliverables (cleaned and readable version of DLL along with full source code converted into Indicators + strategy), but also an open door for further collaboration if need so arises. I am excited about the possibilities this project holds and look forward to bringing your vision to life!
