Senior Android
Architect & Developer

I started Android Development in 2012 inventing a solution for a real problem. Snoring and snore related diseases. SnoreWare, Sleep Data Analysis has brought me through all Android product related processes and currently I have 24 Apps published on Google Play.

Focused on Android Development I kept an eye on Snoreware, while I worked for many companies, clients and projects. I have learnt in each of them, from Wearables, Remote Internet of Things sensors, Cloud Backend, Frontend development, Bluetooth Low Energy or XMPP Communications.

My Telecommunications Engineering background (a five years University Degree equivalent to a MSc. and a BSc. that covers Communications, Electronics and Computer Science) and my curiosity have lead me to develop all technical parts of end-to-end solutions, projects that cover from the electronical sensor to the mobile phone all the way from the IoT device, the Gateway, its data encryption and transfer to the Cloud, display on a Front Panel or reading from an Android Mobile Client in (*) Real Time.

* = Almost Real Time

Projects (2012 - 2022)

Since March 2021 I am developing Apps using Jetpack Compose and the MVI pattern.

  • Dual purpose App - Taxi App for drivers and passengers

    Dual purpose App - Taxi App for drivers and passengers

    My UpWork customer requested the core of a communications system among two different user roles within one App. The goal was to communicate passengers and drivers. This was achieved thanks to the XMPP protocol, a Google Cloud Connections Server and an App Engine Java Application to register users and drivers.
