Summary
👤
Senior🎓
Top SchoolJose Bustillo is a software engineer based in Barranquilla, Colombia, with a strong full-stack focus and eight years of practical experience culminating in hands-on work with React, Redux, Ruby on Rails, Next.js, NestJS, GraphQL and Redis/Sidekiq. At Horbath Technologies he optimized complex queries and indexing to cut response times by an order of magnitude, built a Next.js customer portal tied to a NestJS backend for a potential 600K+ user base, and led security improvements including facial validation and 2FA. He is comfortable across the stack—designing APIs and background jobs, translating Figma into responsive Material-UI components, and maintaining robust test suites with RSpec and Jest—while leveraging AI-assisted development tools to accelerate delivery. Equally at home in agile Scrum teams, he balances performance-first backend work with polished front-end UX and pragmatic business logic reviews. Notably, he pairs systematic performance tuning with practical product impact, turning slow queries and manual flows into scalable, secure features that improve conversion and fraud resilience.
