## What I'm looking for

```text
I'm looking to build and evolve robust full-stack systems, critical business platforms, and cloud-integrated applications, applying my experience in APIs, automation, production support, and scalable architecture.
```

## About

```text
I build and maintain robust full-stack systems for critical business operations, with 92 months of experience across development, infrastructure, and production support.

I'm currently developing and maintaining an ERP for mining companies, delivering operational, management, maintenance, tax, and commercial modules. I implement business rules, validations, REST and GraphQL APIs, authentication, access control, and AWS integrations using NestJS, TypeScript, Angular, RxJS, S3, SQS, and DynamoDB.

I evolved Ward, an investment analysis tool for stocks and real estate funds, building features for presenting, querying, and evaluating market data with C#, ASP.NET, Angular, Bootstrap, and SQL Server. At Grupo ITSS, I also maintained PM RUN, an SAP PM-integrated platform for industrial maintenance planning, including web and mobile applications and REST API integrations.

My background also includes 60 months in DevOps and SRE, supporting production environments, automating provisioning, containerizing applications, implementing CI/CD, monitoring with Zabbix and Grafana, and migrating applications to the cloud.
