BIT_on_Tech™ is the signature I publish under. Bit Veil is the veil itself.
I’m drawn to the space where electronics, software, radio, sensors, and systems meet reality — often in the grey areas where things are
rarely ever just black and white. Not malicious. Not reckless. Just curious, analytical, and willing to open systems
to understand how they truly work.
I’m drawn to systems that don’t fully explain themselves: undocumented behavior, edge cases, and the layers you only see
when you look beneath the surface. My core belief is simple:
“Everything can be analyzed, everything can be understood—if you have the courage to open the lid.”
For me, freedom means being able to inspect, trace, reverse, and reason about a system — not to break it, but to know it.
I operate methodically, but I don’t rely solely on manuals. Some paths aren’t documented. Some answers require going upstream.
Understanding systems by looking beneath the surface.

Contact boundaries
I don’t actively seek projects, and I don’t operate as a consultancy. Any engagement is highly selective and contingent on a problem being technically interesting, well-defined, and personally sustainable for me. If something resonates, I may be open to a conversation.
All messages are read manually. Replies are not guaranteed and should not be expected; they may occur only when relevance and clarity align with my capacity to engage with the problem at an appropriate depth.
Contact formats
Mail and SMS are distinct channels, each with a different intended scope.
Mail
- Preferred for introductions and technical context.
SMS
- Reserved for short, time-critical matters.
