## What I'm looking for

```text
I'm looking to build backend platforms, APIs, and microservices where I can apply Java, Spring, cloud, testing, and technical leadership experience to payment, banking, or SaaS products.
```

## About

```text
I'm currently building Account Closure functionality for Santander Bank at Globant within a hexagonal microservices ecosystem, using Java, Spring Boot, REST, AWS, LocalStack, and automated testing.

I've designed and maintained checkout and payment APIs for PayPal through Taller Technology, and delivered payment and banking platform features for Mercedes-Benz through Starfish using Java, Kotlin, Spring, Kubernetes, React, and Docker.

Earlier, I spent nearly eight years evolving AnswerHub's SaaS platform, building core features and REST APIs, improving performance, supporting search with Elasticsearch, Lucene, and Solr, and integrating Slack and Microsoft Teams. My background also includes technical leadership and Java delivery for Globant, IBM, Nimbuzz, EDS–HP, and Gameloft.
