What I'm looking for

I’m looking to keep improving my knowledge of systems development and databases.

At Opportunity Sistemas, I work as a Suporte de sistema on Fiorilli solutions for public accounting and procurement. I provide technical support and analyze systems, with a focus on relational databases, especially Firebird.

I write, adjust, and optimize SQL queries, identify and correct database inconsistencies, and help resolve technical errors in production environments. When needed, I make direct database interventions to preserve information integrity and align data with business rules.

I use IBExpert to configure connections, analyze errors, and maintain databases. I also assist users, gather requests, and document technical support cases and system improvement requests.

I work with public procurement processes under Law 14.133/21, supporting the organization and review of tender and contract data, price research, and administrative procedures. I’m studying Computer Science at IFRJ and am continually looking to deepen my knowledge of systems development and databases.
