The person behind the poor site.
A little context about who I am, what I work on, and the perspective behind POZHAN.

AI & Software Engineering
Engineering Leadership/Financial Technology
I work at the intersection of software engineering, architecture, AI, and the systems and teams required to turn technology into something useful.
More than a decade building and leading software engineering teams in financial technology.
My experience includes 13 years at a leading global investment bank and, more recently, working in technology at a major financial exchange.
That background shapes how I think about architecture, engineering practices, delivery, risk, collaboration, and the difference between technology that looks interesting and technology that survives real-world constraints.
Things I keep returning to
Software Architecture
System boundaries, trade-offs, evolution, and architecture decisions that remain understandable as systems grow.
Personal Knowledge Systems
Building systems that preserve what I learn and turn accumulated information into usable knowledge.
AI-enabled Productivity
Exploring where AI can remove friction, improve decision-making, and meaningfully change how work gets done.
Self-hosted Infrastructure
Running the tools, platforms, and delivery infrastructure behind my own experiments and projects.
Applied AI
Moving AI ideas beyond demos and into systems that solve real problems reliably.
How I tend to work
A place to document what I learn, build what I want to understand, and connect research, projects, experiments, and knowledge over time.
Explore/Build/Learn/Repeat
Tools I tend to reach for
For ideas, engineering discussions, or things worth exploring.
