I love programming, study new technologies and solve puzzles. I started programming 11 years ago. Currently, I'm a web developer based in Brazil. I'd worked in the Public Sector as a Software Engineer for over 5 years as a fullstack developer (python/django/html/CSS3) using PostgreSQL, Celery, Sentry, Docker, Pytest, CI/CD and Scrum. In my professional career I already worked part-time as IT professor in two differents educational institutes (IFSP and UNIVR). I had been a Mozilla volunteer where I had contributed to optimize the javascript's .split() function. At Mozilla I had improved my knowledges in C++ and Javascript. My last job I worked as a senior software engineer in a startup where I helped to build a WMS (warehouse management system) using Django, Redis, Kubernetes , GraphQL (graphene) and others. The startup had a fast growth , from 30 to 180 clients, where we needed to find solutions to scale up the website to serve all our clients. I am graduated in Analysis and Systems Development (IFSP) and I have specializations in Software Quality (SENAC) and Systems Security (CENES). My goals are to build new systems to help people, improve myself professionally and mentally and meet awesome people. Thank you for your consideration. * Python/Django * Kubernetes * GraphQl * Javascript * GIT * HTML5 * CSS3. * Clean Architecture
