I'm Hayssa Gomes, a fullstack developer from Paulista, Pernambuco, building solutions that connect interface, architecture, performance and security.
I started in 2019, still in school, turning my affinity with systems, logic and creation into continuous learning. Since then, working as a freelancer, I've contributed to projects across many segments , responsive interfaces, APIs, integrations, authentication systems and databases , plus maintenance, bug fixing, versioning and deployment. That path gave me a full view of an application's lifecycle, from the UI down to the back-end structure.
Over time I also came to value the work that happens before implementation: listening to needs, understanding context, researching technologies, gathering requirements and planning the best approach for each challenge. In 2025 I concluded my technical degree in Systems Analysis and Development.
