- As a Principal Architect, I spearheaded the creation of a Unified Data and AI Platform Center of Excellence (CoE).
- I successfully merged three independent analytical stacks-Legacy, Next-Gen, and Suite-specific-into a unified, secure ecosystem deployed on an AWS Control Tower multi-account Landing Zone.
- I championed a 'Managed-Services-First' philosophy, leveraging AWS solutions including MSK, RDS, SageMaker Unified Studio, Managed Flink, DMS, Glue, and EMR.
- I designed scalable Pipeline Reference Architectures using standardized topologies that accommodate both traditional analytics and advanced multi-agentic AI workflows.
- Introduced automated CI/CD via Infrastructure as Code (IaC), eliminating manual ingestion processes and reducing cognitive load for the engineering team.
- Initiated AI-First strategy to maximise value of processed data, integrating with AWS Bedrock to establish a robust Agentic layer.
- Developed a comprehensive framework for managing both batch and real-time datasets across various platforms.
- Implemented diverse data pipeline strategies, including both homogeneous and heterogeneous approaches, to optimise data processing.
- Improved capabilities for real-time data processing and analytical reporting, enabling timely insights and decision-making.
- Centralised security using AWS IAM Identity Center and Server-to-Server (S2S) authentication, enhancing protection of data assets and infrastructure.
- Furthermore, I defined 'Enterprise Readiness' benchmarks for the organization, mandating comprehensive lifecycle management, proactive monitoring, and detailed data lineage and cataloging across all product offerings.
- Facilitated data sharing across lines of business (LOB) while implementing Row-Level Security (RLS) to ensure data integrity.
- Developed scalable architectures for DataLakes, LakeHouses, DataMarts, and Data Warehouses.
- Migrated data from OLTP DB to the snowflake using the S3 Iceberg Table to Snowflake and created a BI dashboard looker.
- Performed regular performance tuning and cost optimisation to enhance system efficiency and reduce expenses.
- Developed an AI Agentic Framework that provides AI Agent Tools via a Low Code/No Code methodology.
- Utilized AWS native tools, OpenSearch, S3 Vector, and PG vector for integration and Knowledge Base (KB) development.
- Created a multi-tenant pipeline for unstructured document processing to integrate legacy data into the system.
