Israel Adeleye

I’m a Database Administrator with 3 years of hands-on experience administering production databases in transactional fintech environments, covering MySQL, SQL Server, and PostgreSQL. I own availability, integrity, security, and performance for systems processing real-time financial transactions across Nigeria, Côte d’Ivoire, and Kenya.

I focus on measurable reliability and speed—query and index tuning to reduce latency, automated backup/point-in-time recovery (PITR), and disaster-recovery testing against defined RPO/RTO targets. I also enforce RBAC and encryption at rest and in transit, aligning controls to PCI-DSS and NDPR, while keeping schema changes flowing to production with zero downtime.

In my most recent role, I built Grafana monitoring for CPU, I/O, lock waits, replication lag, and job failures—cutting incident response time by 35%—and scaled capacity across 28 production databases by reclaiming over 99% of storage with zero data loss. Earlier, as a Database Engineer, I architected a normalized PostgreSQL schema, improved query runtimes by 70%, and delivered ETL/ELT migrations with >99% validation accuracy, supported by Git-based schema deployment pipelines.
