I designed and developed several projects where Internet connectivity was provided to industrial equipment (e.g. press machines, weighing scales or remote controls). The webapps I built let customers monitor their equipment, actuate over it and exploit the data they send to guarantee their correct maintenance.

• Data visualizations in Single-page applications using React and Redux. Interaction with devices using websockets and MQTT protocol.
• Web APIs using AWS API Gateway or Springboot and integrating several authentication services.
• Data ingest using Spark structured streaming, Apache Kafka and AWS Lambda functions.
• Storage using both relational and NoSQL databases like PostgreSQL, DynamoDB o InfluxDB.
• Automated deployment using Serverless framework, Maven and Docker containers.

Lead design, development and maintenance of PT Anywhere,
a web version for the popular network simulator (Cisco Packet Tracer).
Scaling up PT to run more than 500 simultaneous instances per machine using Docker.
Creating web API for managing instance allocation and creation based on the computer load.
Creating tools and visualizations to aid teachers improving students' learning process.
Creating automatic provision scripts for every component of the architecture.
Research on Technology Enhanced Learning within FORGE and weSPOT EU projects.
Additional skills: agile methodologies & problem assessing and solving.

I installed and managed a multi-node OpenStack cloud. This cloud hosted the components of a web application (a remote laboratory) ensuring its high availability. I co-designed and implemented an authentication and authorization mechanism for hardware-constrained devices. I ported the CLIPS rule-based reasoner to Android. Additional skills: team working, self-learning, agile methodologies, working to deadlines & problem assessing and solving.

I taught BSc and MSc students programming (data structures and algorithms in Java) and development tools (VCS, unit testing, continuous integration and issue tracking systems). Additional skills: communication & working to deadlines.
