Architecture and system design
Finding boundaries that make software easier to understand, change, and operate.

Siavash Arzhangi
I work on software systems where architecture, reliability, and product decisions meet.
Most of my work has been around communication platforms: systems that need to stay understandable as they grow. This site is where I keep longer notes from that work.
I tend to care about clear boundaries, calm systems, and decisions that remain explainable later.
Work
A few areas I keep returning to.
Real-time communication
VoIP, SIP, WebRTC, media flows, and the operational details that make them dependable.
Technical direction
Thinking through engineering choices in relation to product needs, team constraints, and the cost of change.
Perspective
I start with the constraints, not the tools.
Before choosing a pattern or a technology, I try to understand where the system can fail, what is likely to change, and what complexity is worth carrying.
