Senior🎓
Top SchoolDavi Alexandre is a Backend Tech Lead based in São Paulo with 15 years of experience building efficient, cost-conscious web systems and services. A pragmatic polyglot rooted in PHP, he routinely applies Java, Ruby, Python, C# and JavaScript when the problem calls for it, and pairs development with hands-on AWS operations and Ansible automation. He has led migrations (Lucene to Elasticsearch), optimized cloud costs, and redesigned internal tooling and front-end style guides to improve developer velocity. As a contributor to the widely used CiviCRM core, he implemented attachment tracking and schema changes that improved data integrity and uploader auditing. He enjoys switching hats—from architecting APIs and search to provisioning dev environments with Vagrant/Packer—and pursues electronics and home automation projects as a creative outlet. Colleagues rely on him for pragmatic, full-stack problem solving and gradual, test-driven improvements to legacy systems.
