Software Engineer at Grupo GPS, developing GPS 360 for 50,000+ users and automating client surveys through WhatsApp.
What I'm looking for
At Grupo GPS, I own end-to-end development of GPS 360, a client portal serving 50,000+ users. I developed its automated delivery of labor and tax documentation to reduce payment withholding, and built its WhatsApp Business Cloud API survey integration, which sent 3,000 messages in its first round.
I also delivered the customer-satisfaction module, which collected about 10,000 responses in its first three months, and migrated 26 database entities across 24 modules from TypeORM to Prisma with zero incidents. Before software engineering, I taught English and coordinated teachers, students, and classes at Wizard by Pearson.
