Oracle Corporation, Redwood Shores, CA 08/12–01/18

Software Engineering Manager

Impact Highlights:

Self-developed CIA (Cloud Instance Automation) that synchronized discrepancies between Dev and QA environments and reduced provision time from 3-4 weeks to 8 hours. Developers are free from Dev-QA squabble over potential bugs due to environmental differences and have time savings resulting from automation to work on other initiatives; financially, the impact is in the order of tens of thousands per developer per year.

Successful execution in implementation and delivery of products that powers multi-data centers

Increased happiness for customers and direct reports by 40%

Process and methodologies:

Shorten SDLC, increased code coverage, and product quality (introduced TDD, scrum, and implemented automation for dev deployment and cloud environment setup, reduced number of bugs due to aforementioned processes, and periodic refactoring rotations to continuously improve and catch any oversights)

Shorten dev and offshore QA iteration (streamlined feedback process with smaller, cleaner handoffs and follow-ups, and resource/environment sharing)

Shorten dev and offshore ops iteration (created and trained a separate 1st and 2nd tier support team to both train new hires in support and alleviate load from developers, conceived and initiated FSB [frequently seen bugs] datastore to address artifact duplications resulting from mismatched versions and concurrent executions discrepancies)

Streamlined dev-integration with other production products (initiated CICD with Jenkins)

With customers’ need in mind, gathered requirements from both internal and external customers, prioritized feature delivery, maintenance fixes, and technical debt – baby steps

Thinking ahead inline with company priorities: modularized products to be independent and RESTful microservices with standard API design practice (openapi)

Authored reporting, workflows, and presentations

Reviewed in code, architecture, and proof of concept prototyping designs

Continuous evaluation of technologies, methodologies, and identifying patterns to simplify/improve existing processes and challenges with healthy team as number one priority in mind

Senior Software Engineer in Cloud Fusion Apps - Lifecycle Management

Design and enhanced introspection implementations to allow environment-self-discovery and self-awareness to reduce the number of manual inputs to the LCM tools

Design and developed enhancements for LCM (Life Cycle Management) tools to support Oracle Cloud applications

Researched, designed, prototyped, and implemented TDE (Transparent Data Encryption) and DatabaseVault support for existing Cloud Data Migration products (P2T, Cloning). Presented, shared, and advice multiple groups on implementation of this solution (TDE, DatabaseVault, Oracle Data Pump, RMAN (recovery manager), Oracle 11gR2, SQLPlus).

Conceived, initiated, designed, and implemented an application that automated generation of complex configuration files involving 220+ properties and discovery from various components/sources, execution of P2T, and generation of common POD level troubleshooting tasks such as restoring databases, checking EM (Enterprise Manager) agents, and turning off certain features on-the-fly. This initiative saves an average developer cost of switching between tasks and 30-45 min on each execution, which is 5-7 times per feature tested (bash, Java, Python, SSH, SCP, EMCC (Oracle Enterprise Manager Cloud Control))

Conceived, initiated, designed, and developed POD maintenance application that automates maintenances of each unique POD to ensure POD environments’ stability and consistency via scheduled tasks to clear space, bounce VMs, restart services, etc across 10 hosts, all of which are blockers to enhancement/defect-fixes validations, and were cleared manually, costing developer an average 1-2 hours per week (bash, Java, crontab, SSH, SCP)

Designed and implemented enhancements and defect-fixes for BBDP(Black Box Deployment Procedure), which parallel installs, seeds, and uniquely configures each instance of FA(fusion apps) on new PODs in Oracle Cloud to ensure security and legality compliances, and functionalities of Fusion Applications that services Oracle Cloud - software as a service platform. (RMAN, DB Catalogue, DB archive, EMCC, EMLMDP(Enterprise Manager Lifecycle Management Deployment Procedure), Oracle DB Snapshot with SunStorage, Java, bash, ruby, sqlplus)

Liaison and coordinated amongst multiple stakeholders in the U.S. and India with different requirements and chased moving targets with tight deadlines for BBDP, as well as provided support of BBDP in Oracle Cloud

Designed and implemented Cloning enhancements and enhancements via health checker platform to validate availability, correctness, and health of all required resources prior to rehydration and cloning. Cloning enables cloning of PODs, which host an instance of all Fusion Application (10hosts), in the Oracle Cloud. (OVM (Oracle Virtual Machine), Java)

Designed, developed, and delegated among team members when necessary, enhancements and defects rectifications for P2T (an application that moves data from production to Test PODs in the Oracle Cloud) to support initiatives such as shared IDM, SSL, properties introspection and discovery, and certifications of other upstream components to ensure compatibility with these components. (Java, bash, EMCC, EMLMDP, Oracle Fusion Apps platform, ODB(Oracle Databases) )

Initiated, conceived, researched, designed, and developed an application, CIA(Cloud Instance Automation), that automated POD OVM provisioning process (10+ hosts with VMs, DBs, and fusion applications on top of those VMs) that takes 2-3 weeks by an error-prone manual process involving both POD specific settings discovery and various components from different sources. An estimated 100+ POD are provisioned in the development environment per month across all LCM groups. The 2-3 weeks process is streamlined to just 7 hours and from 600 to just 30 properties to provision a new POD, which saves developers weeks and makes a significant impact affecting all groups associated with Oracle Cloud. (Oracle Orchestration Framework – manifest driven framework, Java, SSH, bash, OVM, SunStorage, proprietary mappers, ODB, RMAN)

Advised and gave guidance on creative and innovative solutions and architecture for other projects, such as P2T, Snapshot & Restore, and Introspection within a stringent environment.

Researched, demonstrated, and promoted methodologies and technologies such as TDD, Spring, Agile, BDD, etc.
