01 — EXPERIENCE

FISA Group
Customer Care Engineer
Mar 2024 — Feb 2026
Preceded by an internship · Jun 2023 — Jan 2024
Banking software · Production
↳Resolved incidents on banking platforms in production — from business queries to definitive root-cause fixes — owning the full cycle: analysis, patch development, testing and hand-off to QA.
↳Handled live production outages in direct contact with bank clients: joining real-time calls, isolating the failure from logs and coordinating service recovery under pressure.
↳Administered development and QA servers over SSH/SFTP and executed clean production releases, validating my own patches and those of colleagues before every deployment.
↳Worked extensively with Oracle PL/SQL — production queries, triggers and core-banking packages — to diagnose and correct issues at the data level.
↳Developed AI models that classify recurring incidents from the real ticket history, reducing diagnosis time.
