Where technology meets transformation
24+ years of enterprise transformation across Citi, Standard Chartered, Accenture, and Jio Financial Services — governing $3T+ in annual settlement flows. I build automation tools with Python, consult on fintech delivery, teach engineering leadership — and guide those who seek clarity beyond the code.
I am Raja Thilagar R (Raj) — Head of Technology & GCC with 24 years of solution-led, IP-led growth across BFSI, FMCG, and FinTech. I do not grow accounts by renewing contracts. I grow them by building proprietary solutions that become indispensable — then scaling those solutions into reusable accelerators that define the next engagement.
Currently directing the 110-engineer GCC at JIO Bank across 7 legal entities — modernising 52 legacy systems into cloud-native microservices with the Medallion AI Architecture (Bronze-Silver-Gold on Azure ADLS + Databricks) and the 3-Layer AI Decision Boundary Framework (AI-autonomous / AI-recommended / human-only). Production outcomes: 40% release velocity gain · 35% MTTR reduction · 25-35% operational efficiency.
At Accenture, I grew from a data engineering engagement to a $15M AI platform portfolio at Unilever by building Watchtower — a proprietary competitive pricing intelligence platform that became the GenAI Pricing COE Accelerator deployed across 10+ squads, delivering 60% effort reduction and $1M+ annual savings. I also architected and sold the Unilever Enterprise Marketplace Platform roadmap through 2026.
The Citi relationship defines my career. Over 16 years across four employers — Infosys, L&T, Hexaware, Maverick — I built three proprietary IPs that became Citi standards: the Data Lineage Visualisation Engine (drove $30M SCB revenue growth, 8 to 125 FTE in 4 quarters), the Automated FX/MM Reconciliation Engine (protecting >$3T annual settlement volume), and the Automated Job Monitoring Dashboard (300+ jobs, C-suite reporting). A single account grew from $10M to $35M organically through IP, not relationship management.
Eight years physically onsite in the USA — Warren NJ, New York, Tampa, Dallas — reporting directly to CXO-level leadership at Citi and Mellon Financial. Not remote governance. In-room board-level engagement. Available globally for GCC leadership, CTO advisory, and AI transformation programmes.
The Bronze layer is where data first touches your platform. It is also where the most failures originate — not from your code, but from your sources.
"The most powerful technology
I have ever encountered is
a quiet mind."
Twenty-four years in high-pressure banking leaves marks — and gifts. I have sat with both. Now I offer guidance to executives, engineers, and driven professionals who sense there is more.
