What I'm looking for

I'm seeking Senior Database Administrator, Cloud DBA, or Database Engineer roles.

At Paysecure, I administer MongoDB, MariaDB, and Redis for payment orchestration and crypto application projects. I tune queries and indexing, configure high-availability setups, and support incident response and root cause analysis.

Previously, at Formidium, I migrated production MongoDB databases to MongoDB Atlas with zero data loss and administered PostgreSQL systems. I also worked on disaster recovery, performance tuning, security controls, and backup and recovery testing.
