Outcomes
Context
Mi Telcel is how Telcel's customers manage their lines, data and plans. I've designed and built on Telcel's self-service platforms since 2015: features on Mi Telcel's Java microservices, the data-center migration of the business portal, and in 2025 the analysis and first steps of its modernization.
What I built
- 01
Customer features: frequent numbers, suspending a line or IMEI, shared-data packages and prepaid internet offers.
- 02
Integration with 60+ SOAP back-end services behind Feign, Ribbon and Hystrix, with Redis sessions.
- 03
Migration of Mi Telcel Empresas to Telcel's Ixtlahuaca data center (2022–23): high-level design, acceptance tests and the handoff to operations.
- 04
Modernization of the business portal's profile service: Java 8 → 21, Spring Boot 2 → 3.3, Consul replacing Eureka and Config, and Resilience4j.
