Hey! 👋 

I’m a software engineer passionate about building scalable systems that enable rapid innovation and software development

I’m a University of Waterloo Computer Science graduate with 4+ years of experience across high-growth startups including Persona, Wish, and Snapcommerce. I specialize in architecting systems that accelerate product development while maintaining reliability at scale.

At Persona, I’ve built platforms compressing deployment cycles from weeks to same-day releases, supporting 1000+ concurrent users with sub-second response times. Previously at Wish, I developed product review pipelines enhancing quality across 12,000+ merchant items, while at Snapcommerce I architected authentication systems migrating 650,000+ users seamlessly.

What drives me: Creating software that empowers teams to ship faster while maintaining safety and quality. I’m drawn to scaling AI systems responsibly—from real-time data processing to fraud detection to reliable experimentation platforms.

Key accomplishments:
• Server-driven UI systems enabling A/B testing across 50+ component types
• Multi-source SQL platforms with real-time schema introspection at enterprise scale• Graph database architectures tracking 100K+ entities with 99.9% uptime
• Reduced 15,000+ fraudulent accounts through optimized device ID systems
Technical expertise: Full-stack development (TypeScript/React, Ruby on Rails, Go), distributed systems (AWS, Kubernetes), real-time data processing (Snowflake, PostgreSQL, Elasticsearch), workflow orchestration (Temporal).

Excited about software engineering and AI adjacent projects. Always interested in connecting with teams pushing boundaries and building new things.
