Über mich

I'm a senior software developer with +15 years of back-end experience.

I thrive in agile and fast-paced environments particularly in remote-first teams.

I’m a versatile professional and can work as a sole-contributor, integrated in a team or leading one.

--
Experience
--

Back-end development: my work usually involves integration or exposing an API by means of REST/ SOAP Web Services using a SQL database (MySQL, PostgreSQL, etc) or NoSQL (mainly MongoDB but also Neo4J).

I’ve got a strong background with Java (core, multi-threading, JavaFX, etc), JEE (servlets, EJBs, Hibernate, JPA, JMS, JSP, etc) and the Spring Framework (AMQP, Batch, Boot, Cloud, MVC, Data, Integration, Security, Social and Web Flow).

I'm also familiar with JavaScript/ TypeScript (Node.js, NestJS and Express.js), Python (Django, Beautiful Soup, NumPy and Pandas) and Go (Gorilla, gRPC, go-micro, etc).

Blockchain development: I have exposure to the Ethereum ecosystem where I developed, tested and deployed smart contracts using Solidity and Hardhat.

Front-end development: I've implemented simple tasks with Angular.js/ React.js and I’ve got some exposure to HTML, CSS3 and Bootstrap.

Mobile development: I’ve taken part in the development of mobile applications with Android.

Cloud technologies: Amazon AWS and Azure are the cloud providers I’m more experienced with but I’ve also dealt to a minor extent with Google Cloud and Sap HANA cloud.

CD/CI: I’m used to dealing with build libraries like Gradle, NPM and Maven and have also worked with tools like Git, BitBucket, Gitlab, ArgoCD, Octopus, Sonar and Jenkins to perform dev-ops tasks like automatizing processes or implementing pipelines.

Testing: I believe in rigorous unit/ integration testing and have used BDD/ TDD methodologies in combination with Cucumber, Chai, JUnit, Mocka, Mockito, Serenity and Selenium.

Interests
--

I have a genuine interest in the blockchain domain: cryptocurrencies, Bitcoin, Ethereum, DeFi, smart contracts, Solidity, etc.

I'm also interested in traditional finance particularly in compliance topics such as KYC, AML, etc.
