Summary

4 years designing, building, and shipping production software — expert-level in OutSystems (Reactive & Mobile), with real integration work across AWS S3, Microsoft Graph, OpenAI, and Calendly. Delivered multiple end-to-end logistics platforms, built OAuth 2.0 authentication flows from scratch, and embedded interactive 3D visualizations directly into enterprise dashboards. Alongside client work, builds voice-driven AI experiences — interview bots with real-time lip-synced avatars, hand-tracking browser games — combining low-code delivery speed with genuine ML/3D engineering depth.
