SPARK Mobile App Contest

Q1 2016 – Q4 2018

Responsibilities: HTML CSS/SASS JS/jQuery PHP/MySQL AWS

Traditional wordpress site, I built a custom theme based off llorix. SPARK for Autism needed an accompanying website for the duration of the contest to handle contest registration, announcements, and community app voting. I worked on this during my time as an internal dev at the Simons Foundation.

Notable tasks: I opted for a kanban approach to development given that feature development needed to occur around events and announcements that comprised the contest. For registration I connected a CF7 form template to a Googlesheet, such that as users registered, their data would be entered into the spreadsheet, which was shared with stakeholders so they would always be up-to-date without me spending time on plebian tasks like pulling reports. Students were asked to register themselves and their teammates by entering their emails and setting a team password. Teammates would receive an invite email, as all participants had to register in order to be eligible for prize money. To set up voting I started with a general star-voting plugin, added some authentication which hit the SPARK api to determine voting status and access privileges, and modified the JS and PHP according to aesthetic/functional specifications.

Q1 2016 – Q4 2018

Responsibilities: HTML CSS/SASS JS/jQuery PHP/MySQL AWS

Traditional wordpress site, with custom theme built by Madwell. I inherited the task of maintenance, bugfixes, new feature implementation during my time as an internal dev at the Simons Foundation.

Notable tasks: Migrating the site off WP Engine and onto AWS. Getting a team new to Agile to adopt a loosely SCRUM process. Shaving about .1 seconds from the pageload DB query duration with a 30% reduction in DB calls by converting some massive reqs to ajax calls when needed and replacing wp methods with cached vars where applicable.

Q1 2016 – Q4 2018

Responsibilities: HTML CSS/SASS JS/jQuery PHP/MySQL AWS

I inherited the task of maintenance, bugfixes, and new feature implementation during my time as an internal dev at the Simons Foundation. The bugs and tech debt that the initial vendor delivered with the project was a painful reminder of why waterfall development should be avoided at all costs.

Notable tasks: Getting a team new to Agile to adopt a SCRUM process running on 2-week sprints. Diving deeper in MySQL procedures to handle migrations of the alien information schema handed off to us. Migrating an Unfuddle ticket project to our Jira account in a jungle of chunked spreadsheets, field-remapping, and consolidation scripts to preserve ticket comment history. Migrating ACF field schema out of the PHP into which it had been distilled to prevent alteration by non-developer WP admins, back into the DB. Running a strategy-mapping workshop with the team to identify strategic solutions to obstacles (I am forever grateful to Rob Purdie from whom I learned this method). Writing a plugin that works with the arxiv.org api to provide a tool for helping content editors to sync arxiv’s publications authored by foundation scientists with our wordpress publications archive. Restructuring hundreds of daisy-chained SASS files into a more sane and manageable schema.

animated twitterfeed js class

2011
Atmosphere BBDO
conference ipad app/site

Javascript class that pulls tweets from the twitter api based on a search term, populates a carousel with results. jQuery used for animation. Unfortunately, it’s about as reliable as Twitter, which, as I’m writing this, isn’t that reliable, so there are times the api just wont’ return any results. CD requested that I hide the first tweet and then reveal upon page load with a delay so it has an ‘active’ feel to it.

DOWNLOAD SRC


This can be implemented using a script node where you want the carousel to appear in your html page:
 <script type="text/javascript">
                               
                                var twitter_test = new TwitterFeed();
                                twitter_test.search("anything", 4,"orange");
                        
                        </script>


Here’s the class:
function TwitterFeed(){
    
    this.searchPrefix = "http://search.twitter.com/search.json?q=";
    this.searchTerm = "";
    this.maxTweetRetrieve = 5;
    this.tweetData = null;
    this.itemHeight = 0;
    this.linkClass = "#000000";
    this.maxTweets = 10;
    this.displayTweets = [];
    
    // how often do you want to get the tweets? (seconds)
    this.updateInterval = 5;
    
    // the latest tweet is hidden initially. How many seconds after loading do you
    // want it to appear?
    this.initialAnimDelay = 1;
    this.firstrun = true;
    this.getTweetsInt = null;
    this.animInterval = .1;
    this.checkInterval;
    this.intervalSet = false;
    this.maxAttempts = 5;
    this.attemptDelay = 1.5;
    this.attempts = 0;

    this.setupComplete = false;

I need SPACE: browsing FTP host by directory size

2013

DOWNLOAD SRC

I recently needed to free up some diskspace on my webhost, which sounds simple enough, unless you’re like me and your filesystem looks like a hoarder’s reality show. After unsuccessfully poking around for navigation tools that display directory size and allow sorting by size so I could quickly identify the heaviest culprits, I wrote this utility. See de-fanged demo below.

Feel free to let me know of bugs you find, developed on firefox 17.0.1 and so far tests ok on chrome 24.0.1312.52, safari 6.0, IE 8.

Click on the “+” to expand a directory within this view. Click on the directory name to jump to viewing contents of only that directory. Click on “Size” to sort the list by file size, Click on “Name” to sort by name.

Session login default is user ‘me’ password ‘mypass123’ (See ‘Settings’ line 37 to change… it is highly recommended that you change these), authentication times out after 30 minutes.

Installation:
1. change settings to a unique username and pass
2. upload i_need_space.php to your host (yup, just one file).
3. navigate to it via browser
4. when finished with your cleanup, delete i_need_space.php from your host, you don’t want someone stumbling on it and wreaking havoc.
