Ale Sanchez

Ale Sanchez is a Software Engineer located in Madrid, Spain. He began his education at Computer Sciences with a Bachelor's Degree in that field. His final degree project was awarded with two prizes. That moment Ale Sanchez began to think about helping others using his knowledge on Computer Sciences.

After that he did a Master's Degree in Computer Sciences and that was when everything changed. The final project was about to build something (whatever he wanted) as an "entrepreneurship experiment". That was when he first did anything related to entrepreneurship. Ale Sanchez built UnNaranjo in 2017, a complete ecosystem for learning smartphone photography. He recorded online courses, opened a blog, gave face-to-face workshops... That entrepreneurship adventure is still going on. Ale Sanchez's photography blog has now more than 3k visitors each month and the Udemy courses are close to 50k total students.

After a year working full-time getting the project off the ground, Ale Sanchez began to work as Research Assistant for Universidad de Sevilla. He worked as a full-stack developer in the ISA Research group, developing projects for public and private companies.

Then he moved to a new position (and new city). He left his loved Sevilla and moved to Madrid for start working at Rebellion Pay as a Backend Engineer. He worked for a year mainly with NodeJS and a cloud AWS architecture. There he learned a lot more about DevOps and cloud architectures. After a year, he was chosen to plan a migration to a Microservice architecture. Then he was chosen as Tech Lead for a new project in the company built from scratch using microservices. That is his current position in which he is building a microservices architecture over Kubernetes and AWS using NestJS.

That allowed him to deploy and configure a Kubernetes cluster in AWS and a Bare Metal one in a QNAP NAS server.

This was his first job and had the opportunity to work in the Serious Games project. Ale took part in the development of video games for children with cerebral palsy. The game was developed using XNA and a Kinect device, used for controlling the character in-game. The games were mainly question and answer games and the kid had to make some movement with the head, or just say anything in order to select the correct answer. That intern made Ale realise that he could use his knowledge on computer sciences and software engineering for improving people's live in many ways.

Personal projects

Here are some personal projects Ale Sanchez has developed. They are both telegram bots and Alexa skills. Since at work Ale mainly uses JavaScript, all the personal projects listed here are written in Python.

Telegram Projects
Your English Teacher

This bot is for helping people to acquire new vocabulary in english. It is designed for English language students, as it provides word meanings, examples and an audio with the word pronunciation.

Anyone who wants to use this bot just have to talk to it and will receive a new word each day.

Traveller bot

Actually this is a scrapper that retrieves new travel sales every two hours. Then, a bot sends those new travels automatically to a telegram channel.

This channel is intended for people living in Spain, because all the sales are from travels departing Spain.

Alexa Projects

The Alexa Skills listed here are only available for Spanish marketplace.

On a day like today

This skill provides the user with historical moments. Each day the skill has a list with important events that happened on a day like today.

This skill has events related to different fields. It can give facts about art, wars, births and deaths...

True or False

This skill allows the user to play a questions and answers game with Alexa. Alexa will begin to ask true or false questions until the user tells Alexa to stop.

With each question, Alexa will give the user some extra information about the question answered.

Other Projects
Seed/Template project for python telegram bot

This is a skeleton/seed/template project. Since I develop all my telegram bots using the same base library and the same schema, I decided to create a seed project for making my workflow easier, faster and smarter.

This project allows me (and whoever wants to use it) to implement the basic structure of a working telegram bot in minutes, substantially reducing the time and effort I have to invest on developing new bots.

Ale as a Person

Ale Sanchez isn't just a professional. He has also interests, concerns and aspirations. Leaving aside all the cliche interests like travelling, music, reading etcetera, which Ale obviously shares, here are presented other (less-typical) hobbies.

Hobbies and interests
Wood Carving

Ale is just a beginner, but during woodcarving, his mind is completely empty and 100% focused on the hands and the knife.


Ale really likes taking photos. Photography trains the eye and the mind to see things within a different perspective. Ale's work can be explored at Instagram or 500px.

Escape Rooms

Escape Rooms are a great activity to strengthen ties and friendship. Ale is part of a group of friends that usually solve rooms together.


Ale is now beginning to learn rollerblading. He sees that activity as a way of doing exercise and as a test of his motor skills.


Nature is where Ale has to return from time to time. Not always the same place, but he needs to do some hiking or spend a weekend away from the city frequently.


Ale is not embarrassed of saying he loves food. The photo shows a croqueta, a typical spanish dish that is a pleasure for the senses.
