AI Engineer
Turns machine learning into features people can rely on.
Steven has seven years of experience across data engineering, applied machine learning and, more recently, large language model systems. That path shapes how Steven approaches AI features as data problems first: where the information comes from, how quality is measured, and what happens when the model is wrong.
At KrysInfinity, Steven scopes AI work realistically, telling clients where a model will help and where a simpler rule-based approach is the better choice. Every implementation comes with evaluation sets, guardrails and monitoring, so they keep working after launch.
