    My academic major is Environmental Science & Management, and I'm also experienced data analysis and modeling for business and other disciplines, timeseries forecasting, optimization problems, etc. Python is the programming language I'm most fluent in, yet I'm also capable of similar workflows in R or Excel. Projects requiring any these are workable. I can code the entire data science workflow: due diligence, design of experiments, database management, analysis, feature engineering, model selection, optimization, etc. Statistical fundamentals are applicable in every sector and I'm a quick study on prerequisite vernacular for interdisciplinary flexibility. I regularly flex and grow my knowledge and skills in Kaggle data competitions, so I've worked with a broad variety of discipline-specific data applications and types. My areas of interest recently are timeseries decomposition, air pollution, wildfires, biogeochemical cycles, and population dynamics. I've used US Census, USGS, NASA, and other government data APIs to load datasets.

    I am a project management professional and a software developer with 25+ years of experience in diverse business domains and technologies. Over the years, I have worked through all important roles in a software development process, starting out as a Software Engineer, moving on to Software Architect, QA automation expert, Engineering Manager, Project Manager, SAFe Release Train Engineer, Release Manager, and Secure Development Lifecycle Lead. I am fluent in C#, Groovy (for Jira automation), C/C++, and fairly hands-on with Python and Java. Having successfully used and managed Jira Data Center (as well as now discontinued Server edition) over the last 15+ years, I can help you out with anything related to Jira, including but not limited to: * Managing all kinds of Jira artifacts (projects, fields, workflows, schemes, statuses, resolution types, users, groups, roles, Scrum and Kanban boards, dashboards, reports and charts, etc.) * ScriptRunner scripts, including extending Jira user interface, implementing reports that are not supported in Jira out of the box, integration with external systems (SQL databases, LDAP, Salesforce, MS Teams, and any system that supports an API), custom and scripted fields (including data from external systems), custom data extraction, scheduled tasks/CRON jobs, email templates, enforcing rules during workflow transitions in Jira, etc. * If you're struggling with getting your Jira projects and workflows in order, I'm your man. * If your Jira instance is cluttered (too many projects/users/custom fields/workflows, etc.) and hampering your visibility, and you need help with getting a clearer picture and cleaning it up, hit me up! * Need help implementing new user interface elements within Jira (links/buttons that lead to custom configuration dialogs) or projects specific settings that govern workflow behavior on a per project basis? I have done it and I can help you do it too! * Do you need help ramping up your team on Scrum? I have helped multiple teams start off on Scrum and become fully self organized (ask for my LinkedIn profile and check out my experience as a Scrum Master at Intel and Nike). * Are your Scrum teams struggling with concepts such as relative estimation, effective retrospectives, story acceptance criteria, or what to do when and how in Jira for their sprints? I know how to make these concepts easy! * Do you need help with creating external tools in C# and/or Python to export data out of Jira/Confluence in a specific format? Need a tool to bulk update the attributes of your Jira user accounts? Or to look-up extended attributes from your corporate Active Directory instance? Perhaps you have a requirement for regular data pulls from Jira and store it into a SQL database to generate BI reports? If there's something that you need help with, especially involving Jira or Confluence, that you don't see here, just drop me a message. Given my extensive experience, I just might be able to do it for ya!

    I'm guessing you're here because you want something amazing built, but you're either stuck or you aren't sure where to go next. Perhaps you have customers relying on you or you have the latest cool idea. Whatever it is, I'm here to help. PASSIONATE | DEPENDABLE | HONEST I prefer working with folks on long-term engagements, though I'm always willing to help out on one-off projects. Skill set: Full stack web, automation, testing, Python, Node.js, Mongo, Falsk, REST, and many more... Work history: over a decade of tech experience; over 7 of full stack; 4-5 years as a freelancer. What to expect if you work with me: 1. Initial call. I'll ask plenty of questions, listen for what you're looking for, offer guidance and suggestions for anything I think won't work. I'll estimate how long the project will take and bring up any potential roadblocks i see. 2. Development. I'll work on the project, communicating throughout the project. If anything comes up unexpectedly I'll tell you about it. 3. Delivery. This is where I will provide the final project to you for approval. I'm open to modifying anything within the scope of the work if it doesn't match up with expectations. I'm very relational when I work with folks. Everyone is unique and I don't expect each client to get a one-size-fits all. --- A note on the recent 1-star review: I always aim for excellence. With the client it was a fairly simple job that I was more than capable of handling. The job was to fix something on a server. I'm very careful about working something if there's the potential for catastrophe, and checked with everyone to ensure if I worked on this part of the server it wouldn't affect production. However, it was not the case, and production was affected (essentially the IDE I opened it in "updated" some of the settings, breaking a lot of things). I owned my mistake and offered to work with the team to get production back online, but they weren't interested. My mistake was working on their server; instead, I should have set up my own development environment to troubleshoot the issue.
