The most amazing...

...implementations I've handled involved solution architecture using Microservices and event-driven architecture using containers and serverless solutions.

Work Experience

Senior Solution Architect

2004 - PRESENT
Tata Consultancy Services
  • Led the architecture design and implementation for a self-service portal, mobile application, and back-end insurance platform. The design used various AWS services to arrive at a resilient zero-trust architecture as part of the re-platform exercise.
  • Oversaw the design of REST-based microservices implementation for the entire business value chain. I designed multi-channel integration architecture based on a canonical domain model to promote reuse and long-term maintainability.
  • Helped design and implement CI/CD pipelines for continuous integration and deployment into Kubernetes clusters. The solution led to time-saving and GitOps-based standardization of configurations.
  • Worked extensively on performance optimization and design, building foundation components to promote standardization and reuse. These components include authentication, observability, and distributed processing.

Cloud Engineering for a UK Workplace Pension Re-platform Implementation

This project involved designing and implementing an AWS target state solution architecture for a UK workplace pension re-platform implementation using AWS Lambda, Amazon Cognito, Single Sign-on (SSO), API Gateways, Amazon EKS, and Apache Kafka. The solution mainly covers the self-service portal, the mobile journey, and third-party B2B integration with REST APIs and files.

Solution Architecture for Legacy Annuity Platform Migration

I led the design and implementation of a target state architecture to migrate and re-platform multiple legacy annuity platforms into a single modern Jakarta EE platform, improving time to market, operation efficiency, and infrastructure costs. The architecture involved phased implementation of the target state architecture via incremental and iterative implementation of business processes into the new platform.
