Reginaldo in wenigen Worten

Results-oriented software engineer with 12+ years of experience developing, testing, and maintaining enterprise software applications. I am versatile, self-organized, cross-functional capable, with relevant international experience in early-startups to enterprise-class companies.

I am experienced working with local or remotely distributed teams and Scrum/Agile software development process. My task versatility covers: engaging in product brainstorms, technical design discussions, pair programming sessions, assisting hiring processes, code reviews, mentoring, or guiding less or non-experienced tech staff.

Strong JVM Internals knowledge. Main development languages Java, Kotlin, and Scala with practical exposure in frameworks like Spring, Play, Akka, Lagon, Vertx, and as legacy J2EE correlates. Currently, I am skilling myself in React-JS, Angular, Android API.

In the last four years, I've been working mostly with JVM languages and back-end development and data engineering, helping to design more resilient/scalable systems based on micro-services and cloud-oriented architectures and services (AWS, GCP). Handling very-large datasets, building data pipelines, in-memory data grids, and draining to No-SQL databases, RDBMS, streaming data/events with processing engines (like Apache Spark/Hadoop/Storm).

Current main knowledge areas: JVM languages and architecture, Reactive programming, Distributed ledger technology, big-data/No-SQL multi-model DB's, cloud-native architecture, infrastructure as code.
