My ownIndipreneur - Founder of chatcampaigner.com
Aug. 2019 - Oct. 2020I've founded Chat Campaigner (chatcampaigner.com), an online service that brings the power of chatbots, the Facebook / Instagram ads ecosystem and AI to the E-Commerce sector. I've brought this project to life completely on my own: from market research and product design to implementation, and everything in between (finance, web design and development, marketing and sales process definition and implementation; even a bot to support visitors on the website!). This is one of the first chatbot based marketing agencies in Europe. Do you have an E-Commerce that is not doing well? Have a look at our website and let's see what we can do for you!

Teavaro LimitedSenior Software Engineer (contractor)
Jul. 2018 - Mar. 2019RemoteWorking along with the Teavaro technical team, I participate in the architectural design, maintenance and evolution of the Teavaro Digital Marketing Platform writing (as usual) Scala code. In order to help devs in understanding the complex business domain and express it in clean code even readable by business stakeholders (as it we want it to speak the business language and look pretty much like pseudocode at the highest levels of abstraction) we are borrowing some DDD concepts, such us ubiquitous language and bounded contexts; and also techniques, such as context mapping. As code design principles we stick to a ports and adapters high level architecture, with different compilation units and compile time dependencies for each of those. The core module we are working on is pure functional, making extensive use of the finally tagless encoding to represent effects as values in an abstract way. For the interpretation, we tend to use the cats-effects arsenal, using intermediate compilation layers to inject dependencies using the reader monad when required. We also religiously follow the "make illegal states unrepresentable" principle using the Scala type system to encode business semantics into types as much as the language allows us to do so. We tend to replace if expressions (we don't use if as an statement at all) with type classes for cleaner design and code extensibility. We use monads all over the place to tell apart error conditions (and short-circuit computations) without polluting our code with defensive programming dirt. We use an applicative style instead not only for validation but also to express complex execution flows that involve interaction with third party systems to separate the description of those flows from it's implementations details (for example concurrency management). We leverage functional programming to the max we are capable of to solve complex problems in a way we can easily (and locally) reason about. And we learn on the go as required.
CllucSoftware Engineer (Scala)
Apr. 2017 - Jun. 2018Madrid Area, SpainAs part of a really talented crew we use Scala and perform somewhat as full stack engineers in order to bring Blockchain technology to the masses. How? Making it simple and usable as mobile Apps have got us used to do things nowadays in the digital world.
Among our toys we have: Play framework (with Silhouette), Postgres, Terraform, Ansible, Scala (with cats) and Parity as Ethereum client.
GeenySenior Scala Engineer
Jan. 2017 - Apr. 2017Berlin Area, GermanyAs part of a large team of really talented people, I leverage the power of functional and reactive programming to bring the Internet Of Things closer to it's users. Some of our toys: Scala, akka, AWS, Docker, Terraform, Mesos, Marathon, node.js and Play Framework. Disclaimer: I haven't played with them all in this position.
Self employedScala engineer in personal projects

Gennion SolutionsLead Architect / Scala developer
Jun. 2015 - Sep. 2016Madrid Area, SpainAs en engineer with also an architect role my goal at Gennion is to strive for the best possible architectural design and implementation of our smart spaces services platform. We leverage the power of a distributed microservices design, reactive technology and functional programming to give our clients outstanding business intelligence on their Big / fast Data Streams. My key activities:
* Find out with the rest of the technical team the best architectural design and technological stack to build an scalable and performant solution for all our clients.
* Provide the analytics team with the infrastructure and APIs they need to improve the actionable information and insights we get from our devices data.
* Play a key role to adopt a devops approach in our team. Design and implement the required elements to build, test and deploy our services into a Kubernetes cluster using Docker containers; and operate those in production.
* Design and implement the continuous integration / continuous deployment pipeline to be used from the very first iteration of our software development process. We don't want to start coding without having all the tools needed to automatically build, test and deploy our code to any environment.
* Write code to let the magic happen. Be one of the main contributors of the production codebase. The tools we are using for that (to name a few): Java, Scala, Akka, RabbitMQ, MongoDB, Docker, Kubernetes, Google Cloud Platform and our talent and imagination.
