About Rajkumar Chatterjee

18+ years. 4 Continents. One consistent problem - enterprises approve budgets and buy tools, but still struggle to turn data into a business asset.That is the gap I close.I rather than chasing AI out of. I believe a successful AI-ready data platform is only possible when a robust is the foundation. Without it, AI is just an expensive experiment:I have led transformations for UK investment banks, built a - that secured $, and helped organizations retire £+ s - not by adding complexity, but by defining the right architecture. My experience spans the UK, US, Aus and India across multiple domains.In 2026, I founded MentisReach with a core belief: a great data platform is worthless if the team cannot run it after the consultant leaves. My approach is \"Build + Enable.\" I do not just validate your architecture; I build the internal capability to sustain it:/: For organizations needing a hands-on data leader for a 3 to 9 month transformation or a long-term part-time strategic advisor. I specialize in - ensuring your data foundation is treated as a product, governed, reusable, and scalable - to prevent wasted spend on hype projects: Architecture validation, cost-optimization, and AI readiness advisory for CXOs - vendor-neutral, outcome-focused, and aligned to regulatory compliance including TCFD and SFDR: Custom masterclasses and workshops in Data Modeling, Data Mesh, and Modern Data Platforms for engineering teams and lateral hires: 1:1 coaching for senior engineers and delivery managers making the transition into Data Architecture and leadership roles:AI-Ready Data Platforms - Data as a Product - Data Mesh - Data Vault 2.0 - Azure - Databricks - Snowflake - AWS - GCP,/.
