I am an enthusiastic individual always eager to communicate with all stakeholders and very familiar with the open-source projects, startups and enterprises. My strengths lie in identifying problems and proposing solutions for automating people's everyday life, devising innovative product features in software engineering around all life-cycles, from inception to production. At a professional level, I have (re)architected and developed a variety of computer systems, ranging from specialized softwares to network protocols. Senior software engineering experience developing cloud-native, high-scalable systems based on microservices and/or serverless architecture; 20+ years developing solutions for startups and in cooperation with large companies, such as Samsung, Petrobras, Nokia, Epson and BlackBerry. Currently, I am very excited about the new era of decentralized solutions based on Blockchain and Smart Contracts that will raise a series of new applications (Web 3.0), such as Decentralized Finance (DeFi), Non-Fungible Token (NFT), Metaverse and some others that we even don't know yet. At a research level, I have worked as a full-time lecturer and researcher, giving classes about Distributed Systems and Computer Networks. In my Ph.D. I have proposed and developed the Global Media Transmission Protocol (GMTP), a cross-layer optimized protocol for massive distribution of live multimedia content, supporting P2P sockets in the transport layer and building a network of favors in the network layer, implemented in the Linux kernel.

Bachelor of Information Systems (2023.1), software developer with 6 year experience with Electrical Engineering background. In the last years I've been involved in some fintech projects, developing backend features, maintaining data pipelines (processing, transforming, loading) and deploying to cloud. Also, contributing to escalate and enhance products. Nowadays, during my free time, I'm studying about Financial Systems, watching the macro economic cycles and how do they interact with our lives. Last, not least, I strongly believe that technology came to improve our life quality and social environment. I'm passionate about personal exchanges and good feeding.

Rafael N.

Vetted Network developer in Brazil (UTC-3)

I'm a Software Engineer with 6 years of experience building distributed systems in the financial and network industries. I grew the most at Siden. I got a chance to work in an environment of fast iterations in the development cycle of software and I also was introduced to a lot of different technologies in a very brief moment of time, with a great team of engineers. I also was assigned more responsibility as I designed and implemented entire microservices and integrations with other services. I would highlight two projects. The first one is a payment processing microservice that I developed at SICOOB Pagamentos and that currently processes millions of transactions on a daily basis, it was developed using Spring Boot (Java) and it acts as a gateway to the Central Bank of Brazil. The second one is a service that I developed at my last job site (Siden) and it was a certificate manager that integrated other services and issued/renewed/revoked certificates on devices that the company was manufacturing. It was used extensively and it was developed using Go. If you feel that you need more details about these projects please let me know. Reach out so we can talk more about my strengths and weaknesses in the Computer Science field.
