    Data Science, Engineering, and Analytics



    I create Analytical Dashboards in the Cloud to aggregate, filter, display, and monitor metrics


    Looker-Dashboard

    • In order to demonstrate my Cloud Data Analytics skills, I've built a dashboard in Google Looker to monitor the status of loans. First, I displayed the total amount of outstanding loans, followed by a breakdown by loan status. Next, I highlighted the top 10 states with the highest total count of outstanding loans and identified customers who own their homes outright and have "Current" loans. Finally, I enabled cross-filtering on the loan status dashboard to improve interactivity and explored automatic refresh options for the visualizations.

    I can perform Univariate and Multivariate Analysis


    Looker-Dashboard

    • For this project, I used data analysis tools such as Jupyter Notebooks, Numpy, Pandas, Matplotlib, and Python. The project called for me to analyze a large data set from a food delivery service and make observations from the derived data and plots. Finally, I made some recommendations on how the food delivery service can maximize profits based on these observations.

    I use Tableau to aggregate, filter, and visualize data for useful Business Insights


    Tableau Visualization

    • This project utilizes public lightning strike data from 2016-18. Once imported into Tableau, I plotted the data using Barplots, a Heatmap, a Boxplot, and a Histogram, filtering by Year, Quarter, and Month and using Bins for the Histogram. I used both the Tableau online and the desktop version to complete these visualizations.

    I create Apps that wrangle, ingest, and visualize data for Real-Time Insights


    • Hacker News Jobs Splunk Dashboard App - I created this App using Splunk Enterprise, Python, and the HackerNews API. It displays detailed info about job postings on the site and allows deeper drilling for actionable insights.

    DevOps



    I produced the 'DevOps Shop' video series


    The DevOps Shop is a series of 18 videos on YouTube with over 10,000 views.





    My DevOps projects and repos


    • DIY DevOps Dashboard - I made this project as a way for those new to DevOps to get started with the basic technologies involved (GitHub, Docker, GitLab, Jenkins, Terraform, Elasticsearch). It provides the user with an all-in-one place to see their progress and to better understand how these different tools interact in the DevOps.


    • Simple NetDevOps CI - This is a simple and free CI pipeline that receives a webhook from GitHub whenever anything changes in the GitHub repo. The webhook triggers a build action in Jenkins that runs a shell script, clones the GitHub repo, and creates a virtual environment to run pytest. Currently, the repo I am cloning from is based on Ansible, so my tests are for Ansible playbooks and inventory files, but those can be adapted to test whatever you want. If a pytest fails, a message with details is sent to a Webex space, and the build fails as well.

    • Swiss Army Conf - Written in Python, this tool offers those monitoring a network device with 3 avenues for viewing device configuration: NETCONF, RESTCONF and SSH. The results are automatically logged in XML, JSON and text formats, respectively.

    • Ansible Automation - Automate the creation of ACLs, routing reports, local files, and more using variables and conditionals in Ansible playbooks. Presented at multiple Cisco Lives.
    • Tech Word of the Day - A Webex bot, written in Python, which sends a random tech word to a Webex Space and to LinkedIn daily, using APIs. Anyone can join: https://eurl.io/#3wNrmU0-1
    • Meeting Agenda and Recap - Automates the posting of meeting agendas and recaps in Webex spaces. It also keeps records of the agendas and recaps sent. Written in Python.

    Full-Stack Python development



    I create full-stack Python apps


    • El Hambre (The Hunger) - I made this ambitious charitable app from scratch using Python, Django, the Stripe payment API, and the SendGrid email API. It collected donations and sent emails containing Amazon Gift Card codes generated asynchronously via the AWS Gift Card API.


    • Sent Heard - This innovative project utilized Python, Django, PostgreSQL, Amazon S3, and Stripe to record, store, deliver, and display customer data securely. It was hosted on PythonAnywhere.com
