Fintech Software Architect — Legacy Migration & SaaS Conversion

13 years architecting and running production financial systems at ICB (Investment Corporation of Bangladesh) — double-entry ledgers, portfolio management and investment operations serving 50,000+ customers and over a million transactions a year. I lead migrations of live, regulated systems off Oracle Forms and AngularJS onto modern .NET 8 architectures without stopping the business, and verify AI-assisted delivery the way an audit does, not the way a demo does.

“I don't pitch mockups. I've modernized systems a national financial institution runs its books on, without taking them offline — and I bring the same audit-grade verification to AI-assisted migrations for clients like BrandTrader (US) and PQS (Japan).”
