Owned logistics products end to end, migrating six legacy modules and adding four new ones while introducing bounded-memory processing, Kafka, Redis and AWS CDK.
As a Fullstack Software Engineer at Tracktec S.A. (2024-present) in Santiago, Chile, I build B2B SaaS products for industrial telemetry and logistics.
I own SGT Reservas V2 end to end, defining its versioned API architecture and migrating six legacy modules while delivering four new modules. I also delivered Embarques to Google Play and the App Store, including Auth0, route selection, OCR of Chilean identity cards and seat assignment.
For high-volume reports, I established bounded-memory processing over millions of records, buffered S3 writes and live job status over WebSockets and Server-Sent Events. I improved Angular monitoring and event-explorer views with server-side pagination, virtualized tables and real-time updates, and introduced Redis caching, Kafka integration and AWS CDK infrastructure-as-code standards.
