About

Marvin Dsouza is an experienced full-stack developer with over 11 years of relevant experience in the field. He is a skilled professional with expertise in creating web apps and services with ownership of front/back end components. Marvin is proficient in backend development with a focus on designing APIs, data models, and pipelines, as well as microservices. He is also adept at developing front ends for SPAs using React/Redux with a focus on usability and workflow efficiency. Marvin is passionate about supporting end-users through documentation, tutorial videos, feedback loops, and mentoring teams. He is well-versed in languages such as Python, C, JavaScript/Node.js, Erlang, and YANG. Marvin is also proficient in tools/frameworks such as Django, Flask, Express, ORM, React, Redux, LESS, Sass, Webpack, pyang, and confd. Additionally, he has experience working with databases such as MySQL, PostgreSQL, and MongoDB. Currently working as a Software Engineer at Meta, Marvin has previously worked as a Senior Software Engineer at Cisco and as a Software Engineer 4 at Juniper Networks. At Cisco, Marvin developed a web app to map nodes between YANG trees using drag-n-drop and generate platform-specific code in C, Erlang, etc. This app is currently being used by hundreds of Cisco developers to map Openconfig/IETF models to native models and provide backward compatibility to native models. He also developed build time pyang based infra to validate YANG models, capture backward incompatible changes, and check model compliance before model-based changes are committed. At Juniper Networks, Marvin co-wrote Juniper Playground, a scalable distributed web app that allows users to learn Junos OS APIs by trying them out in a terminal/editor on their web browser inside their dedicated container. He also built a distributed web service to allow processing Google protocol buffer files to generate backward compatibility and conformance reports. This service allows validation of proto files based on user-defined conformance rules and backward compatibility checks to allow version control on published APIs. Marvin holds a Master of Science (MS) degree in Computer Engineering from San Jose State University and a Bachelor of Engineering (BE) degree in Computer Engineering from Don Bosco Institute of Technology. He is skilled in various technologies such as Software Engineering, Backend, Javascript, Web, Redux, MySQL, Infra, Django, Docker, MongoDB, Microservices, Flask, Python, NodeJS, and RabbitMQ.
