Summary
👤
Senior🎓
Top SchoolAlexander Leyva is a software engineer with 11 years of experience building reliable, production-grade web applications and payment integrations, currently at AWS in Vancouver. He brings strong full-stack skills demonstrated by contributions to the popular recurly-js library—improving TypeScript types, payment flows (3DS2, iDeal, Apple/Google Pay) and external gateway integrations. Prior roles span startups and scale-ups where he led front-end and back-end efforts at FullStack Labs, Mercado Libre, and others, and he has taught JavaScript and SPA patterns. He favors readable, maintainable code—“if you have to read your code twice, it can be written better”—and applies that discipline to complex payment and integration work. Comfortable across TypeScript, Angular/AngularJS, and systems integrating hardware standards like ONVIF, he blends practical engineering with a habit of improving developer experience.
