• Created a technical roadmap for the entire back-end ecosystem for a novel Verance product, including ingestion and device management services, data processing, data storage and visualization. Led the high-level architecture for all components and identified the technologies and skills needed for implementation. The solution utilized AWS technologies such as Redshift, DynamoDB, EMR, Kinesis Firehose, Lambda, S3 and ECS. Successfully drove the project from business vision to production release in 10 months.• Managed a multi-discipline technical team of 6 engineers in the implementation of all components. Coordinated relationships with stakeholders and ensured the successful completion of all projects. • Lead the adoption of Cloud Solutions (AWS), DevOps processes and Agile Project Management (Scrum) for the development of the new product. Communicated the benefits to the executives and trained personnel in AWS tools and technologies, Agile Central and Jira. This enabled the team to meet all deadlines for implementation and keep costs low.• Lead the data architecture, data modeling, data dictionary creation and data lineage mapping process for all components for both NoSQL (DynamoDB) and SQL (Redshift, RDS) platforms using ER Studio.• Architected and led the development of a Big Data processing pipeline using Spark Scala and EMR. Due to the adoption of AWS, DevOps and Agile it was deployed to production in 6 months.

• Architected, designed and led implementation of a Big Data system used by HP Print management to determine new marketing strategies and drive the direction of new products and services. Specified architectural requirements and design for ingestion, processing, storage and reporting, and determined the technology stack for the solution. Consulted and reviewed high and low-level design utilizing JBOSS, Hadoop Map/Reduce, HBase and Vertica. Coordinated the development and delivered on time in spite of a short time line, steep learning curves and geographically distributed resources across the US, India, Malaysia and Singapore.• Provided deep technical expertise for Vertica. Published best practices for querying, table/projection design and loading mechanisms for large volumes of data on Vertica. Guided teams’ implementation of the best practices to improve the performance of an unstable multi-tenant 52-node Vertica cluster. Implemented Vertica data loading scripts and Vertica tables and projections. Continually optimized and updated projections and queries based on interactions with stakeholders. Interacted with the internal Vertica DBA team and external Vertica support to further optimize the cluster for all tenants on the Vertica cluster.

• Created short, mid and long-term roadmaps for all applications in the Information Management domain for HP Inkjet Cartridge Manufacturing. Requested and justified projects each fiscal year to implement aspects of the roadmap. Identified and coordinated resources for projects, and reviewed architecture and high-level design for each project in the domain.• Architected and led the design of a high volume auto-scaling data load and storage solution for world-wide HP Inkjet Cartridge Manufacturing that dropped the data latency from hours to minutes.• Established and enforced database and data architecture standards across the organization - the use of Erwin, Oracle and SQL Server naming standards, usage of PL/SQL, data dictionary standards and conceptual modeling standards. Guided and participated in the high and low-level design of Data Engineering projects across the Information Management domain for Inkjet Cartridge manufacturing.

• Created data collection, reporting and analysis solutions for Inkjet Cartridge Manufacturing and testing.• Defined logical and physical data models and defined and enforced worldwide data collection specifications for manufacturing tools.• Educated other data modelers on the appropriate uses for normalized vs. dimensional (star schema) modeling techniques. Reviewed and approved physical data models for projects across the organization.• Designed, implemented and monitored data processing jobs using Oracle PL/SQL and SQL Server Stored Procedures that were tightly integrated with Inkjet Cartridge manufacturing lines and test areas.• Designed and wrote reports for Inkjet Cartridge Manufacturing and test data using both in-house and COTS tools, against both tightly controlled and loose data sources.• Managed and maintained Oracle and SQL Server databases used for both real-time data collection and data warehousing. Monitored and tuned performance, backups and statistics jobs. Managed user access.• Educated data consumers on the use of SQL. Wrote, debugged and optimized data consumer queries against large volumes of data.

• Provided query tuning and analysis support on Oracle, Informix and SQL Server databases for data consumers on four different sites around the world for Inkjet Cartridge R&D and manufacturing process data.• Designed, implemented and maintained an automated system for Statistical Process Control on a manufacturing line in San Diego.• Lead the monitoring and improvement of operations for Inkjet supply and packaging lines in San Diego. Monitored data collection and SPC processes, as well as systems responsible for package labeling.• Assisted in the management of nine Informix databases used for Inkjet Cartridge manufacturing and R&D testing, including updating tables and stored procedures, archival and backup processes, disaster recovery and data consumer query construction and tuning.• Created and maintained Erwin diagrams and database dictionaries for all physical data models.Architected a replacement for a third-party Manufacturing Execution system. Coordinated replacement activities, monitored the new system.• Was on-call 24/7 for one week out of every six to address manufacturing line issues.
