If you want to know more about me, please read my blog at https://jorge.aguilera.soy
In every project I have worked I participated in budget and recruitment although my main role is technical leader. I design the architecture, decide and configure collaborative tools, assign tasks, and work close to developers team in an agile process
I believe in the Open Source Spirit and, as such, I have created and participated in several international projects. I am the main contributor of asciidoctor-extensions, asciidoctor-themes and groogle open source projects. I am also the main responsible for the 101-scripts blog about Groovy and author of the book "Tutorial Básico de Asciidoctor" (sold in Amazon). Also I’m an asidual tech talker in differents meetups as MadridGuG, Codemotion and esLibre


As system administrator I have proven experience installing and maintaining, in house or cloud, Windows and Linux machines

As developper I have 25 years of experience programming in C, C++, Java, Javascript, Groovy languages. Also I have proven experience with SpringFramework stack (SpringBatch, SpringBoot, SpringIntegration,…​) Grails 1.x, 2.x and 3.x and Micronaut, also starting with Quarkus. I work usually with Gradle, Maven and Git and organize my tasks with Jira. I have developed solutions in disparate environments as web applications, desktop, cash machine, point of sales, web servers and android devices.

As software architect I designed solutions for middle and large distribute environments applying SOA, REST, JMS (with Rabbitmq). I’ve some experience with Google Cloud and Amazon AWS implementing solutions using Google Cloud Run or Lambdas.

As solution provider I develop rapid prototypes to gain visibility arround the problem to solve, helping the customer to discover what is looking for.

As team lead I have experience working with small groups (5-6) using agile methodologies, helping them to discover how to use the tools, frameworks and how to focus in testing approaches.

Some achievements

Tymit migration of a monolithic application in Grails 3.x to a microservices architecture with Grails 3.x, Micronaut and Quarkus. I redesigned and splitted the code into differents projects, delimiting business boundaries and applying a step by step methodology moving different parts in each iteration. Design the integration of new microservices during this migration using Rest and Event Driven approachs

Plaxo a Groovy framework oriented to QA to test backends and front navigation for an international airline company that replace SoapUI. It allows to different teams share Specs test, Geb navigations automations and generate evidences for each test.

SII Design and implement a microservices event drive architecture in order to allow consume huge files of invoices (over 10K per request) and send all of them via SOAP to the Agencia Tributaria Española.

Gredos Design and development of a Java application oriented to optimize the stock of stores (90+) using historical data series and applying statistics functions for the forecast of sales in a non-assisted fashion. After two years, all stores have been able to optimize their stok, reducing costs and improving their estimation of workload.

Frappe Full redesign of ERP proprietary from Informix 4GL to a web application using Grails and Ajax Javascript (Dojo). Requirement analysis, architecture design and main developper. No install procedures, increased number of users, different business views and drastically improved management of characteristics and prices of articles are some of the new improvements

Merlin Development of a touch application (JavaFX & SOAP) for the control of an airline crew. Reduce the time spent signing in an old 3270 terminal using a modern interface from several minutes to few seconds

SONAR Grails REST backend & AngularJS application to collect children’s comment. WordPress plugin to show them into the corporate portal


Principal Software at Tymit

As Principal Software and due my experience with Grails I assume the responsability of propose improvements to the application as migration to a microservice architecture, new functionalities, etc.

We have transformed a monolithic application with releases every month to multiple independent services with releases every week improving the general performance.

Design the integration of new microservices during this migration using Rest and Event Driven approachs

Startign from a closed Docker swarm where main communication between services was RabbitMQ we moved to a more decouple architecture with:

  • Authorization service using signed JWT in Micronaut

  • Proxy View (Backend For Frontend) in Micronaut

  • Communicating different services (some in Grails and others in Quarkus) using SQS, Rest

Playing a Principal Software Developer role I assume the responsability of redising the monolithic application plus doing support task to the QA team helping in the automatization of the release process.

Software Architect at Enxendra

Company focused about digital signature as e-invoice, sign documents with local and cloud certificates, etc

As software architect I’m working transforming a monolithic application into a microservices architecture. We are introducing new languages and frameworks, mainly Spring Boot and Groovy/Grails, meanwhile we adapt functionality to this new architecture without disrupt the service.

In this way, I have introduced Docker and Docker Compose as the new way to deploy applications to avoid typical problems about configuration, versions, and so on. Also I have created different Jenkins’s jobs to implement a CD/CI process.
