Seventeen years building enterprise data infrastructure at the institutions where downtime is measured in millions.
Mayank Sethi is a Principal Database Engineer working at the intersection of enterprise data infrastructure and the financial institutions that depend on it. Over seventeen years, he has built and governed critical data platforms at two of the most demanding firms in fixed-income and asset management — PIMCO, one of the world's largest fixed-income managers, and Group1001, an $80 billion insurance and asset management enterprise.
His work lives where database architecture meets cloud security automation and AI-driven governance. He has originated SCALER, a novel framework for credential lifecycle automation; published peer-reviewed research in the American Journal of Technology; and shipped production systems governing hundreds of thousands of sensitive data columns.
He writes about what actually breaks at scale — and the patterns engineers use to keep it from breaking again.
Most enterprises manage database credentials reactively — rotated after incidents, tracked in spreadsheets, governed by manual checklists.
SCALER is a formal state-machine model that treats credential lifecycle as a first-class engineering problem. Provision → activate → rotate → audit → retire — each transition observable, automated, and idempotent.
Designed and deployed at Group1001, SCALER now governs 1,000+ service accounts across 150+ application teams. Integrated with ServiceNow for automated lifecycle workflows. Zero production incidents to date.
Production classification pipeline spanning 950,000 columns across 40+ source systems. Cortex ML + rules engine tags columns automatically; dynamic masking enforces policies at query time. Ships with a React/FastAPI governance app for human overrides and audit trails.
Led enterprise-wide Oracle Exadata consolidation at PIMCO — decommissioning 200+ physical database servers and migrating workloads to a consolidated Exadata architecture. Zero downtime across critical risk and portfolio systems.
Open-source multi-source financial signal pipeline. Aggregates technical indicators, news sentiment, social media, congressional disclosures, and earnings data. Novel latency budget framework and two-tier deduplication.
Selectively open to conversations about enterprise data architecture, speaking invitations, and advisory discussions in financial data infrastructure.
If you're building something at scale — and hitting hard problems — let's talk.
