Many streaming services ignore older adults. I designed and engineered a high-performance web app with senior-friendly accessibility controls and a serverless backend supporting 300+ active users.

Email production at Serasa Experian was bottlenecked by manual HTML coding. I built a visual compiler that reduced campaign build times from 80 minutes down to just 10.

Gamification for an EdTech platform. I designed and built real-time leaderboards using server-side rendering (SSR) and aggressive caching to handle massive launch-day traffic spikes.

Support Queue

Customer support lacked a triage system, leaving all tickets in a single pool. I researched user pain points, designed an automated priority queue, and reduced average wait times by 22%.

Reading docs only gets you so far. I designed and built a multimodal AI sandbox to master and de-risk token streaming and model orchestration before client work.

Language teachers run 1:1 and group lessons across Zoom, WhatsApp, and disconnected docs. I built a live classroom that puts video, interactive activities, and a CEFR-mapped progress trail on one screen.

// ABOUT THE HUMAN

Human intention, amplified by AI.

Today, anyone can generate a user interface with AI in seconds. But a great product needs direction, clear design, and real user empathy. To me, "Human intention, amplified by AI" means using technology to build faster, but keeping human vision in control.

Outside of work, I love travel and new adventures. I pay close attention to details and I am always open to change. I love learning about new AI tools, and I really have fun doing this every day.
