Ask HN: Freelancer? Seeking freelancer? (January 2017)

SEEKING WORK - Remote, am in US Eastern Time

I solve data-related problems. I use data science and full-stack data development tools to generate analysis and applications. Whether this means providing advice on your current data practices, creating an ETL web application, creating a real-time updating dashboard, or undertaking one-time statistical analyses, I am able to help you make sense of your data to make better business decisions. I follow an agile, test-driven development methodology.

Have worked for Twitter, the Inter-American Development Bank, numerous startups.

Languages: Python, R, JS.

Some things I’ve worked on recently: - Consulted with a startup and provided ongoing advocacy about their data ecosystem, data warehousing practices, and data acquisition pipelines. - Built end-to-end applications that produce a data-related product - One-off analyses and visualizations of business-critical data to gain additional insight

Other tech tools I work with:

- Web Frameworks: Python's Django and Flask

- Visualization Libraries: R's ggplot2 and Python's matplotlib for static visualizations. Python's Bokeh and JavaScript's D3 for dynamic visualizations. Python's Bokeh for dashboards.

- Big Data Tools: Pig and Scalding are my preferred Map Reduce abstraction layers. Together with Python, R, and Bash, I have experience utilizing these tools within the Hadoop File System to make large amounts of data manageable.

- Back End: Nginx, Gunicorn, MySQL-driven databases

- Version Control: Git, Subversion

- Testing Frameworks: Selenium- Machine Learning and Statistics: Ranked in Kaggle's top 1%. MIT degree, lab focus was on computational statistics.

- Version Control (Git, SVN), Continuous Integration, Test-Driven Development, Nginx, HDFS, Pig, Scala, Scalding.

SEEKING FREELANCERS - REMOTE (anywhere on the globe)

Our calling is to be behind the scenes, using technology to enhance impact and sustainability, as well as reducing the distractions and stress on leaders.

We're in the middle of a sales spike which will result in many multi-faceted needs. Even without the sales spike, we have a lot to work on! Some focus areas:

- Java development: Spring and Hibernate are requirements. Bonus points for jOOQ. - PHP development: Well-rounded, but initially WordPress focused. - Systems and API integration: Tie 3rd party solutions together into cohesive, automated strategies. A mix of API deep-dives, business requirements analysis, and custom development. Systems typically include payment and donation platforms, CRM, donor retention, mailing, etc. - Task automation. This is super multifaceted, but the typicals (Python, Perl, etc.) come up frequently. - Mobile app developers: Native and hybrid apps are in the pipeline. - Front-end developers

Must be fun and easy going. Must be used to remote, asynchronous environments. Our primary focus is serving others!

If that describes you, I'd love to chat! Brett Meyer brett@3riverdev.com
