One of the biggest hurdles to B2B AI adoption is unrestricted agency. When I designed the Feature Training Center for SparkAGI, I treated Permissions as a primary user experience. Users need more than just a chatbot, they need AI Governance. By designing a modular toggle system, I’ve made it possible to: Control Scope: Limit the AI to specific business functions (like Quote Gen) until the team is ready for full automation. Manage Dependencies: The UI proactively flags what’s missing (e.g., Payment integration required), preventing broken workflows before they happen. Align Knowledge: Every toggle defines the boundary of the AI’s thought process. This is how design solves the Risk problem in Enterprise AI System. #AIGovernance #EnterpriseSaaS #ProductArchitecture #InteractionDesign #B2BTech

Built a custom Python B2B lead generation tool that scrapes business directories, bypasses Cloudflare/WAF bot-detection using curl_cffi and Playwright, and syncs verified leads in real-time to Google Sheets for outreach campaigns.

LUXE Studio is a photo and video editing app built around focused tools instead of one crowded editor.

I worked across product design, native iOS implementation, subscriptions, QA, localization, App Store presentation, and release support.

The project shows my end-to-end mobile product workflow: shaping the app experience, shipping polished editing features, refining launch assets, and supporting the product through release.
