PROFESSIONAL EXPERIENCE

Confidential, Irving, Texas

Senior Engineer

Responsibilities:

• Developed SpringBoot microservices to enable stop/start of remote services like stop/start of Horn/Lights/Engine/Door, etc
• Used SNS to publish messages to SQS queues and SpringBoot listener to fetch the remote service status from SQS.
• Developed AWS Lambda functions to process reports uploaded to S3.
• Used T3 core services such as TS, GS, DS as the core logic processes and sent out remote messages to the vehicles via Gateway services.
• Used Docker to to create docker images and push them to Amazon ecr.
• Exposed REST API and integrated with Legacy systems via SOAP Web Services.
• Used JBoss as the On Prem App Server where ear and war files were deployed for the various applications.
• Used threads to asynchronously make SOAP requests to the audit/trace server and also for keeping track of SLA for overall performance of the transactions.
• Used Redis for caching.
• Involved in Agile methodology in 2 week sprints. Stories as deliverables.
• Used ELK Stack for logging.
• Developed CICD deployment pipeline
• Used OAuth2 JWT for authentication and authorization between microservices.

Environment: Jboss EAP 7.1, Java 8, AWS Lambda, SNS, SQS, REST, SOAP, Docker, SpringBoot, Maven, Jenkins, Sonar, GIT, Kibana, ELK Stack

Confidential, Addison, Texas

• Development of SSO for user authentication in lieu of Entitlement services.
• Developed common component for adding mandatory header info to the SOAP requests to MSP
• Designed and developed the SOAP WSDLs in the Web Services layer to provide services to UCRS(Collections), IVR, Online Banking.
• Designed RESTful API’s for Mule for Customer Svc to talk to the MISP services.
• Developed the amortization calculator as dockerized Spring Boot Microservices and deployed to AWS.

Senior J2EE Engineer

Responsibilities:

• PCI Retail Debit Card project adopted the PCI-DSS (Payment Card Industry Data Security Standard) policies to safe guard Master Card PAN data.
• Development of CTS(Central Token Services), a J2EE application which exposes REST API through a proxy housed in the DataPower/Akana platform. The capability of CTS is to provide tokenization and detokenization of PAN data from Master Card. All requests come into CTS through Datapower proxy.
• CTS handles high volume transactions( each trnx 10 millisec roundtrip), 100 transactions/sec thruput due to debit card ISO transactions while caching the Master Card PAN in IBM Extreme Scale.
• Developed these services as Jersey based RESTful services which were used for tokenization and detokenization of PANs and tokens
• Used JPA/Hibernate to access tokens from SQL Server DB
• Used Kafka to asynchronously log audit event data to DB from the various components.
• Development of SOAP WebService to Master Card and Voltage appliance.
• Installation and configuration of Voltage Appliance. Voltage engine provides a reliable implementation of the FPE(Format Preserving Encryption) tokenization algorithm producing FPE tokens from Master Card PANs.
• Configuration of Thales HSM with Voltage. Used as the key protection and management in encrypting the token table mapping by Voltage.
• Deisgn and review of ISO Converter, Socket TCI/IP based app.
• Involved in architecture of CTS wrt horizontal and vertical scalability, high availability, System Interaction Diagrams.
• Involved in Security design details wrt CIA(Confidentiality, Integrity, Availability), data in-flight(TLS) and data at-rest, Identity Mgmt, Certificate Mgmt. Cert based mutual auth.
• Authentication & authorization between CTS-Proxy and CTS server, CTS server and Voltage, CTS server & DB.
• Non-invasive event probe for CTS health check. Performance monitoring using Dynatrace, DCRum.
