SOFTWARE ENGINEERING · PLATFORM · PRODUCTION
I design and develop web systems, APIs, data flows, integrations, and delivery infrastructure. I can own a focused engineering area or take responsibility from requirement to working release.
My professional path has moved through Linux and cloud infrastructure, SRE/reliability, platform/DevOps, and backend/product systems.

Core features
Scope of responsibility
Product design, frontend, backend, data, integrations, and deployment.
System architecture
The interface, application layer, data, integrations, infrastructure, and delivery need to be designed as parts of one system.
System architecture
From the first user action to data, integrations, and production infrastructure.
Request → rules → data & integrations
05 · Technology system
Tools used in the documented projects, grouped by interface, application, data, infrastructure, and delivery.
What users see and interact with.
requests
Server-side logic, permissions, calculations and business workflows.
logic
Storage, relationships, integrity and data processing.
persistence
The environment in which the system operates.
runtime
How changes are validated and released to production.
release
Experience and responsibility
