I am software developer, inventor, patent author, startup founder, CEO, CTO and freelancer with over 20+ years of experience, most of it in high tech software companies. I can help you with the development of your platform no matter the stage of the journey you are at.
You can leverage my lifetime curiosity in technology and materialize it into software architecture, back‐end or frontend/mobile development, database design, startup advice, inventions, patents and much more.
TECHNICAL STRENGTHS
Backend development: Java, C++, C, Shell Scripting, Ruby
Frontend development: Dart, Flutter
Infrastructure: Kubernetes, Microk8s, Docker AWS, Bare Metal, Google Cloud
Delivery Platforms: Jenkins, GoCD
IDEs: Qt Creator, Visual Studio, Android Studio, Eclipse, IntelliJ
Version Control: Git, Gerrit, Mercurial, Subversion
Platforms: Linux, iOS, Android, Windows, QNX
QA tools: JUnit, CppUnit, Cucumber, Jenkins, Jira
Storage: MongoDB, SQLite, LevelDB, AWS S3
Recommendations from my clients:
“I had the pleasure to work with Francisco for 1 year. Francisco has strong technical skills (Flutter & beyond), is quick & eager to learn if some knowledge is missing, very flexible and highly committed to the tasks assigned. Furthermore he comes with own initiatives/ideas and is very diligent towards documenting code/processes/… for future need. Therefore I can strongly recommend him!“

Present
I built the first real estate platform in Europe that allows its users to find their new living place by com‐
mute time to work, daycare or anywhere else by car, public transport or bike. I released mobile apps for
both Android and iOS, as well as a web version of the platform. In summary, I took care of all aspects
related to startup founding and platform development, including:
· Pioneering the industry: I invented and built a functionality never seen before in Europe, even for big
real estate software platform companies. Searching for place to live by commute time is a feature that
only Doopla provides.
· Backend and frontend development: Writing both backend (Java 11 and Spring Boot) and fronted
software (mobile development with Dart and Flutter) for the platform.
· Database management: Designed the database (MongoDB) schema and its connections to the back‐
end software. I also built scripts to regularly made backups of the database and defined processes for
disaster recovery.
· Miscellaneous work: Building a startup from the ground up requires knowledge of a very wide variety of technologies, including security (DDoS prevention), infrastructure (Docker and Kubernetes on
bare metal), scripting (Shell), REST API definition and documentation (OpenApi), performance optimizations, technology exploration, documentation and much more.
The technologies I got to work with include Java 11, Spring Boot, Dart (with null safety), Flutter, Docker,
Kubernetes and Microk8s, iOS and Android development, MongoDB, Shell Scripting, REST APIs, Authentication‐Authorization‐Accounting with Firebase, OpenApi for automatic code generation, SSL certificate management (Cert‐Manager with LetsEncrypt), security implementation including brute force auth prevention, freelance work management, platform marketing and many more.

I brought technical leadership, best practices and software development processes to a cross-functional
architecture and research team, including:
· Technical exploration: Writing architecture studies to support technology choices on microservices
architecture.
· Technical leadership: Managing outsourced development from the technical point of view, ensuring
system designs are not compromised by their implementation and no corners have been cut.
The skills I'm developing in this post include microservices architecture deployed using Docker and Kubernetes,
Java, MongoDB and NGINX, among others.
