And led a team for 2 years. I'm used to fast-paced and adaptive environments such as startups, working close to many roles Currently, I find myself deeply engaged in the world of functional, statically typed programming with Rust and Typescript

    With more than 10 years of experience, I went from working by myself with technologies that I was comfortable with to tasks across different teams worldwide with stacks that I seldom used... I developed the FRONT-END for web apps using React, Angular and AngularJS. Worked as a BACK-END engineer with Java, NodeJS, asp.net(C#) and python. MOBILE-DEVELOPMENT with React Native including Android specific features in an "offline first" asset tracking application. Configured the basic INFRA-STRUCTURE for many projects including containers with Docker and clusters with Kubernetes. Good experience with the AWS environment. I also can handle different types of DATABASES. There were cases in which applications were struggling to complete requests when using relational databases and I got amazing results by migrating/caching specific parts of them to a better fit such as DynamoDB, Redis and MongoDB for those cases. I know good strategies to reduce costs and boost performance with CACHE and COLD STORAGE for major projects. With strong fundamentals, I am very resilient and I will be happy to help you.

    I have years of experience in analyzing and developing systems in many market segments and different-sized companies. I am selftaught, I have the ability to report independently of hierarchical levels, deal with changes, critical environments, work with diverse technologies, roles, and projects. Also, I try to be proactive and follow up on new technologies available in the market. I believe that a bad mood and lack of discussions and alignments can bring problems to the team, so I do my best to be available and doublecheck the information to ensure the deliveries, keep the great mood, and the good vibes.

    Hello, my name is Daniel I live in Brazil and work as a freelancer. I develop apps with Bubble.io because I believe that application development can be fast and easy. Our clients can not wait, so the tools to develop their solutions need to provide an environment where it's possible to quickly implement the ideas and release an MVP. With this concept in mind, I started developing applications using no-code and low-code approaches. For the last two years, I have been working as a web developer at Bubble.io. So I think I have the basic knowledge needed to help you develop your project.
