Designing secure, scalable lending and collections platforms from the ground up.
I am a Solution Architect with 17+ years of experience across SaaS platform engineering, microservices, cloud-native architecture, IAM, DevOps, and AI-enabled system design. I currently architect core lending, loan management, and collections platforms with strong focus on multi-tenancy, security, scalability, and delivery rigor.

About
Architecting enterprise-grade financial platforms
My recent work has centered on designing a multi-tenant lending platform covering Loan Management System (LMS), collections, centralized IAM, platform integration, and cloud engineering foundations. I have designed the LMS and Collections platform from scratch with modular microservices, strong tenant isolation, configurable behavior, secure integration patterns, and scalable deployment foundations.
A major part of my work has been building the complete IAM and authorization architecture using Keycloak, including tenant-aware realm strategy, authentication flows, token handling, RBAC/ABAC-aligned access control, and secure microservice integration.
I also work closely with engineering teams on design governance, code and architecture review, performance and scalability considerations, DevOps setup, CI/CD pipeline standardization, and reusable platform patterns. More recently, I have been exploring Agentic AI, MCP-based integrations, guardrails, and AI-enabled architecture patterns for enterprise financial services.
Core focus:
Translate complex business problems into robust, secure, configurable platforms that are built for scale.
