Alex Peng

Software Engineer
Open to new opportunities

I'm a Software Engineer based in Toronto with over seven years of experience building full-stack products across fintech, SaaS, and hospitality tech. I'm currently looking for my next role.

Most recently at Touchbistro, where I worked on the end-to-end delivery of merchant onboarding for DoorDash integrations across the merchant base, and built an internal guest management platform in Node.js and React.

Before that at Jobber, I helped migrate the mobile codebase from Ember.js to React Native, integrated Twilio Programmable Voice for real-time calling, and architected a Redis pub/sub presence system for low-latency state sync. I also mentored engineers on GraphQL best practices and led the delivery of an online booking feature that directly drove customer activation.

I also previously worked or consulted at Scotiabank, BMO, and MPAC.

My stack: TypeScript, React, Node.js, Ruby on Rails, PostgreSQL, Redis. I care about reliability, clean API design, and code that's easy to hand off.

If you're hiring or want to chat, I'd love to hear from you.
