Banks and insurers hold millions of pieces of personal information — social security numbers, policy details, account balances. Regulators require them to know exactly where all of it sits and who can reach it. Most institutions answer that question by hand, which makes the answer slow, expensive, and out of date the moment it is produced.
Mayank Sethi builds the systems that answer it automatically. At PIMCO, one of the world's largest fixed-income managers, and now at Group1001, an insurance holding company with $86.1 billion under management, he has turned manual compliance work into governed platforms that produce their own evidence.
The discipline is the same across everything he has built: use the cheapest method that can decide correctly, escalate only the genuinely hard cases to expensive technology, keep a human able to override without creating a second source of truth, and design so the thing survives being moved to another company under a different regulator. Three of his four frameworks were built at one institution and rebuilt at a second.
He is an IEEE Senior Member, a grade held by roughly ten percent of the institute's half-million members. He has published three peer-reviewed papers and serves the field as a reviewer, program committee member and awards judge.
He writes about what actually breaks at scale — and the patterns engineers use to keep it from breaking again.
