Senior Full-Stack Engineer building Laravel SaaS products, including an offline-first PWA with a custom sync layer.
BrazilI merged four systems into one modular Laravel platform and built an offline-first PWA for field workers at sites without internet. Its custom sync layer handles conflict detection, user-resolved conflicts, version history, and automatic retries.
At XpertiON Sistemas, I built real-time collaborative editing for about 400 daily users and an invoicing module integrated with government and payment APIs. I also maintain B2B products with Laravel, Vue.js, MySQL/PostgreSQL, and AWS.
