### Senior Staff Software Engineer, Deployments @ InfluxData
Jan 2021 – Jan 2022 | San Francisco Bay Area
I was responsible for building tools and deploying changes to production across multiple clouds and regions. My role also involved managing and improving the CI/CD pipelines, such as GitHub Actions, CircleCI, and ArgoCD. I created monitoring and alerting tools to enable teams to troubleshoot and enhance overall deployment capabilities, velocity, and quality. I scripted builds to support the CI/CD tools using CMake and Makefile. I enforced quality and security in various automated solutions, reviewed code changes submitted to production, and configured micro-services and deployment pipelines. 

I was responsible for troubleshooting Kubernetes services and deployments on various clusters such as AWS, Azure, and GCP. I contributed to upstream fixes and features to open-source CI/CD pipeline tools, participated in daily stand-ups, and collaborated with my team. I managed the GitHub repositories, developed and maintained GitHub Actions and CircleCI as part of the CI process, and coordinated with other infrastructure teams to meet goals. 

Pipeline build and test scripts (GHA) were written and maintained in Golang and Bash. I supported developers in building tools and environments when deploying micro-services to multiple cluster environments such as AWS, Azure, and GCP. I documented runbooks outlining new build tools and processes involved in the SDLC. 

I improved and monitored the CI/CD release pipeline, including fixing, triaging, and enhancing the delivery system with Continuous integration and delivery. Additionally, I was part of the incident response team and helped address any issues that may arise, including Level 3 support on a 24/7 on-call rotation. I used tools such as Graylog, Prometheus, and PagerDuty.

### Senior Staff Build/Continuous Integration Engineer @ Gigamon

I managed engineering tools and services, drove product releases across different teams, improved engineering and support tools, optimized processes and workflows, and ensured timely and effective releases. In addition, I automated the build, deployment, and testing using Jenkins/pipeline script. I managed the source code repository (GIT) while maintaining Gerrit code review repository hooks that helped provision check-ins by developers and integrated information to both Atlassian JIRA and Jfrog Artifactory. Furthermore, I developed build tools using Python and Shell script as part of the deployment process and was responsible for writing Jenkins pipelines in Groovy (DSL).

I supported the build pipeline workflows, including embedded software C++ builds. I set up Docker-based builds with a private Docker registry and repository via Jfrog Artifactory, which managed all the build dependencies and enforced the build promotion model. I also managed user accounts and helped with cost optimization and analysis to maximize savings and minimize risk and cost. 

Moreover, I have significant experience writing Jenkins Shared Libraries and pipelines in Groovy script. I managed the Jenkins servers to build, test, and deploy various tooling and our product line applications. Additionally, I was responsible for Black Duck security scan analysis reports as part of every major product release and static analysis Coverity scan. I flagged security and operational risks with the legal department for proper licensing.

I managed the development and deployment of packages for our products. My responsibilities included creating and maintaining build and deployment scripts and building jobs executed from our Jenkins CI servers. I work closely with the development and QA teams to ensure that builds remain clean and efficient. As the manager of the source code repository (Subversion), I am responsible for the branching/merging and standard library management required throughout the development and release cycle. Our release schedule is quite aggressive, so I must be readily available to address any potential changes that could affect the release target date. I upload extensions to the Chrome WebStore (CWS) for each release and carefully document everything in Confluence (Atlassian).

As a project lead, duties require me to work with a Business Analyst to understand the technical requirements for projects, work closely with QA and Integration engineers testing releases, and closely work with deployment engineers on all projects deployed to production. All specification and design documents adhere to implementing GDUP (Goals Driven Unified Process) compliance. Our company requires me to develop all design documents using a Rational Unified Process (RUP). I am fluent in writing use cases, components, and sequence diagrams as part of the development process. I also provide production support for all issues reported for WBI, which has exposed my current experience with server administration of our web and our EAI applications.    Development includes working with PeopleSoft adapters used to communicate with PeopleSoft’s Component Interface and Data Handlers for XML development and working with JDBC Adapters communicating with DB2, Oracle databases, and AS400 systems. Recent projects include a production application written entirely in Java, which allows one of our field offices to attain up-to-date loan origination transactions processed by our main office. I also developed and maintained a web-based J2EE-compliant web application (Insight) used with WBI as part of both a developer toolkit and a production support application. Insight is written using the following web technologies: JSP/JSTL/JavaScript/Servlets/HTML and CSS. Insight’s front end was developed utilizing JSP, HTML, and JavaScript. The backend involves EJBs, JSTL, and Custom TagLibs, all hosted within WebSphere and interfacing with Oracle 9i.

### Software Integration Engineer @ Ascent Logic Corp.

Developed client/server applications as a way of collecting information to be parsed back into our software product, RDD.COM.  Responsibilities included integrating all code updates and fixes into our configuration code development management system at ALC.  I initially started as a QA Tester and transitioned to a Software Integration Engineer, as I focused myself more as a software developer.  I was joined to the development group where I programmed in Microsoft Visual Basic and wrote applications for exclusive customers.  I was given the extended opportunity to travel to customer offices and demo my custom applications that extended our products API to suit our customer’s needs.  My experience at ALC greatly broadened my influencing and verbal skills as a developer.
