What I'm looking for

I'm looking to build production-critical platforms where strong Laravel architecture, resilient integrations, data migrations, and disciplined testing create measurable value. I value technical ownership, pragmatic engineering, and opportunities to mentor teams.

At Reimpact, I own the architecture and technical direction for a multi-tenant Laravel and Vue.js SaaS platform handling 200k+ annual transactions across 50+ enterprise clients. I lead four engineers while building REST APIs, enterprise integrations, tenant-scoped data models, and online migrations without downtime.

I've led an 18-month CodeIgniter-to-Laravel migration at Go2 Logistics with zero data loss, built AWS event-processing backends for healthcare telemetry at Globant, and delivered regulated insurance e-commerce for Banco Consorcio. I build Laravel applications for real production stakes: tested code, resilient integrations, clean migrations, and performance-minded databases.
