Petro Hrys
Digital infrastructure builder.
Building and researching search systems, AI architectures, automation, and independent digital products.
Positioning
I work independently on the layer beneath the visible web — how search systems index and retrieve content, how language models surface information, and how discovery is shifting from keyword matching toward entity and intent understanding. Alongside the research, I build and maintain a small set of independent digital products.
Current focus
- Search-system indexing behavior
- Retrieval & LLM surfacing
- Independent product maintenance
