Armstrong Olusoji
Applied AI engineer building the infrastructure for domain-specific AI co-pilots.
I design and ship systems that turn deep domain knowledge into intelligent products — from the primitives layer up. Below is the work: platforms, shipped tools, and the engineering breakdowns behind them.
Projects
Poysis
The infrastructure layer for domain-specific AI co-pilots.
A no-code platform that lets domain experts compose customer-facing AI co-pilots from seven reusable primitives — no transformer knowledge required.
Product Scout
Semantic search that understands what shoppers mean, not just what they type.
A Shopify app that replaces keyword search with intent-aware discovery — the first Poysis primitive deployed in production e-commerce.
Simasia
A brand-tone guardrail that scores whether an AI reply sounds like you — and steers it until it does.
A small, cheap Python library: one frozen embedding model plus one logistic head per brand. It scores any LLM output 0–1, explains the score with real examples, and refines the reply until it passes.
