Data Engineer at DGLine S.R.L., who cut response times 40% on an SQL Server and ASP.NET Core 8 B2B portal.

At DGLine S.R.L., I refactored business logic and optimized queries and stored procedures for an editorial B2B portal, reducing response times by 40%. I also developed a Python connector to migrate ServiceDesk tickets to Redmine through REST APIs, with repeatable runs and duplicate prevention.

At UNLB – United Nations Logistics Base, I worked on ETL flows for the UN logistics system and developed monthly operational reporting in Power BI. Earlier, at Fincons Group S.P.A., I worked on a data warehouse for Cornèr Bank SA and rewrote PL/SQL stored procedures for Zurich Assurances to reduce execution times.
