Hi, I'm Robert!

• Architected and delivered a fully autonomous alert triage pipeline, from signal detection to root-cause diagnosis to stakeholder notification. Response time fell 85%, from 30 minutes to under 3 per incident.
• Scaled coverage to 78+ alert recipes across 5 critical journeys (Deposit, Withdrawal, GamePlay, Login, Registration), each giving a confidence-scored verdict grounded in live SQL evidence.
• Built an AI-driven daily anomaly sweep that replaced a 60-minute manual routine with 5 minutes, with provider-level and hour-level attribution.
• Set up the "explain-why" analytics layer for journey monitoring: 62+ alert rules across 4 markets, so ops teams act on root causes, not symptoms.
• Ran daily UX health reporting on registration conversion, deposit success, retention and game errors, surfacing cross-market patterns for product and engineering.

• Led end-to-end UX for risk-adjustment products, turning technical clinician workflows (HCC coding, chart retrieval, encounter submission) into focused, low-load flows.
• Ran research with clinicians and operators, then turned insights into prototypes and experiments that moved coding accuracy and throughput.
• Designed and evolved an accessible (WCAG 2.1+) design system used across the product suite.
• Explored responsible AI patterns: explainable UI, human-in-the-loop review and trust-building micro-interactions.
• Used AI-assisted prototyping (Lovable, Bolt, GitHub Copilot) to shorten the path from idea to clickable prototype and validate flows with stakeholders sooner.

• Designed a cross-platform web and mobile experience for clinicians and nurses: real-time messaging, task management and patient monitoring.
• Ran interviews, built personas and mapped nursing-home journeys, then took wireframes through to interactive prototypes.
• Built an accessible visual system that works for users with very different levels of tech confidence.

• Led UX across patient-management, telehealth and EHR products, balancing business goals, technical limits and user needs.
• Ran qualitative research, thematic analysis and observation studies; the personas, journey maps and wireframes drove design decisions.
• Maintained a shared design system that kept every product consistent and accessible as the portfolio grew.

• Owned end-to-end UX for a new decentralised exchange, built to make crypto trading less daunting for new users.
• Led cross-functional research and testing that produced a personalised first-time experience. Daily trading volume grew 100%, and new-user acquisition followed.
• Turned design, business constraints and accessibility into a repeatable UCD process, and supported design-to-engineering handoff.

• Designed end-to-end UX/UI for a top-tier Vietnamese banking app: UX artefacts, UI, prototypes and interaction patterns shipped at scale.
• Set mobile guidelines, patterns and component libraries used across the org, and cleared blockers between design, BA and engineering.
• Brought design thinking to cross-functional teams, turning qualitative and quantitative data into insights that shaped the roadmap.

• Built a school-management platform from concept to MVP: UX/UI documentation, project plan, task breakdown and change-request management.

• Designed and helped launch Vietnam's first online career-fair platform from zero: wireframes, sitemaps and flow diagrams.
• Shipped the MVP and iterated on feedback from early users.
