What I'm looking for

I'm looking forward to find a place where I can:

Deliver value to customers and be proud of it
Learn from my teammates
Write clean code
Scratch my head while solving issues
Keep work/life balance but been available when problems arise

I'm a software developer since I was a child. So, when I graduated from high school I started to my professional career.

I did the whole expected career from junior to manager in a multinational company. The main project was the firmware of Fiscal Printers (mainly in C). There I've learned how to develop code with a strong focus on quality in a limited resources environment. Bugs could lead to really expensive solutions. Also I developed a lot of side projects in the Fiscal Printer ecosystem which includes: integration with big companies software, tools for government, libraries for third party developers. From those tasks I've learned to adapt to client requirements and restrictions.

After the pandemic I realized that my real passion is still be a software developer, learn new technologies and work together with other developers. So, I decided to follow my heart and focused on development of web applications with Python and React.

My first step was to develop a solution to automate the invoicing of a family business using government and marketplaces APIs. Later on I decided to quit my manager job and start a new journey in B-Yond as a Full Stack developer. There we where responsible for developing a solution for Ooredoo Qatar to help them to monitor the state of the communications network during the World Cup. There I worked with microservices in Python with a lot of SQL queries to a Vertica DB and, also worked in UI with React and Next.js. Now I'm ready to continue with a new challenges in another place.
