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.

Why Your Multi-Account AWS Data Platform Needs Centralized DNS

Running Apache Spark or Amazon EMR across multiple AWS accounts without centralized DNS is a hidden infrastructure risk. Deep-dive: Route53 architecture, EMR-specific patterns, Kerberos, and a five-phase migration strategy.
