## About

```text
At Kpler, I work on backend services and data pipelines for large-scale maritime data, using Java, Spring Boot, Scala, Python, and Kafka. I built and maintained real-time and batch processing flows handling millions of records, keeping data reliable and fresh for downstream services.

I’ve used production metrics and profiling to identify API and database bottlenecks, improving response times by up to 6x in some cases. I also take part in the design and evolution of event-driven systems, alongside technical design, code reviews, and production troubleshooting.

At NET2GRID, I built and evolved backend systems and APIs for production applications, contributing to product and technical design decisions. Earlier, as a Web Developer Intern at Sigmasoft S.A., I integrated ERP systems with Magento applications through PHP components and REST-based integrations with C# services.
