Profile:

I am an Enterprise Data Architect, Cognizant Technology Solutions with over 18 years of experience in ETL, Business Intelligence, and Cloud technologies. I specialize in leading data solutions for financial and healthcare clients, with expertise in tools like Informatica, Power BI, and AWS. My focus is on delivering scalable, high-impact projects while ensuring data quality and compliance.

Over the last decade, I have demonstrated significant performance in Cloud Technologies, with a particular focus on Data Analytics, Data Migration, and Modernization. My career reflects a series of successful large-scale cloud migration and data modernization projects that have transformed technology infrastructures for several leading organizations, driving both efficiency and substantial financial impact.

JP Morgan Chase –  Enterprise Data Architect  (April 2022 – Present)

In my most recent role at JP Morgan Chase, I led the Data Modernization- Cards ABI to AWS Cloud Migration project, which focused on transforming card data products, including Card Referential Data and Pricing Tier Data, from Teradata to AWS Cloud with Snowflake provisioning. This migration optimized compute power through burst computing capabilities, delivering 30% additional efficiency in global data centers and resulting in annual cost savings of $200 million. My role included leading the migration of 200+ source files and developing a new ETL framework using Java and Spark, which streamlined data loading from AWS S3 to Snowflake. This initiative not only improved data availability but also increased user engagement, benefiting over 5 million users.

JP Morgan Chase – Senior Technical Project Lead (March 2021 – April 2022)

During this period, I played a key role in the MBODS to Cassandra Migration project, where we decommissioned the legacy DB2 system and migrated the Mortgage Banking Operational Data Store (MBODS) to Cassandra. This migration improved system performance by 50%, enhanced responsiveness, and supported a scalable architecture. Additionally, I introduced a microservices-based approach that replaced legacy SOAP services, minimizing system downtime and increasing the availability of critical services. The project contributed $15 million in annual revenue and increased the system’s efficiency, allowing for seamless handling of unstructured data loads.

Cigna Health Care – Senior Technical Project Lead (Feb 2020 – March 2021)

I led the CMS Interoperability and Patient Access Rule implementation at Cigna, which allowed customers to access their healthcare data through third-party applications. This project leveraged the HL7 FHIR standard for API integration and increased the processing capacity by 200%. Additionally, transaction times were reduced by 90%, and payment processing errors decreased tenfold. This initiative expanded the user base by 90% and generated an additional $20 million in annual revenue by enhancing data accessibility and operational efficiency.

Cigna Health Care – Senior Technology Specialist (Jan 2018 – Feb 2020)

As part of Cigna's efforts to modernize its healthcare analytics, I developed a predictive analytics algorithm aimed at improving medicine usage and pricing transparency. I also led the development of data solutions for strategic decision-making, which increased system processing capacity by 400% and reduced security incidents by 95%. This project contributed an additional $2 million in annual revenue, and the implementation of machine learning models significantly enhanced data-driven insights, improving customer satisfaction.

JP Morgan Chase – Technical Project Lead (Mar 2016 – Jan 2018)

I spearheaded the Info1 Audit Remediation project at JP Morgan Chase, which focused on enhancing security and compliance for Unix host groups and database user profiles. This initiative improved audit compliance, reducing errors from 38% to 4%, and increased system efficiency by 75%. Additionally, migrating data from SQL Server to Snowflake resulted in a significant reduction in security incidents (95%) and optimized the organization's audit processes, contributing to the project's overall success.

Cigna Health Care – Senior Software Engineer (Jan 2015 – Mar 2016)

In this role, I worked on Cigna's BI Analytics Customer 360 View project, which aimed to create a unified view of customer data across multiple lines of business. By integrating customer information from various healthcare products, the project provided valuable insights into customer behaviors and preferences, boosting the company’s ability to target marketing efforts effectively. This resulted in an 80% increase in the user base and contributed $50 million in annual revenue.

Across all of these roles, I have consistently led initiatives that modernized data systems and implemented cloud-based solutions, resulting in improved operational efficiency, enhanced security, and tangible business outcomes. My expertise in cloud technologies, data migration, and advanced analytics has enabled organizations to scale their systems, reduce costs, and better leverage data for strategic decision-making.
