Konstantinos Anastasiou

Founding product designer for an enterprise AI model training platform. Shipped MVP and early iterations while defining UX patterns, workflows, and a design system from zero. Designed an evaluation and diagnostics loop where failure modes become training data so bad scores turn into diagnoses and then fixes. Rebuilt the dataset builder around templated, inspectable starting points to make input schemas legible. Created artifact-centric information architecture with explicit dependency and lineage tracking across datasets, models, evaluators, inference configurations, and experiment graphs. Designed operational jobs and alerting UX for long-running training/evaluation with email notifications, and embedded with ML engineering to translate metrics, drift, and pipelines into interfaces enterprise teams can use.

Designed UX for ML-driven anomaly detection to surface model-flagged outliers across thousands of Kubernetes metrics. Paired anomaly scores with dense visual telemetry so engineers could judge whether a flag was real before taking action. Architected modular data-visualisation UX for dark/light SRE workflows and data-heavy tables, including colour-safe encodings beyond the red/green convention.

Embedded contract product designer selected into Toptal’s top 3% of global designers. Led UX across multiple applications for Carrier Global (Oct 2023–Feb 2025), including smart home app redesign and an AI-assisted field service technician app. Built and governed an atomic multi-mode mobile design system across ~100 components, versioned via a contribution model to prevent breaking imports, and fixed issues identified through component detachment analytics. Integrated smart home with Leap’s virtual power plant platform, adapting flows to different state programme rules (e.g., Texas vs California). Also led end-to-end UX/UI for EquitySet (stock research & investment platform), including discovery, personas, information architecture, screening/backtesting flows, and data visualization components; revenue increased 98% after launch and it won a Benzinga Global Fintech Award (2023).
