InitialView's main product is called an Interview in a box (IIAB). I developed a full testing page for interviewees to test their connection and hardware before the actual interview so that the interview would go as smoothly as possible. I streamlined the video editing web pages that allow editors to select the best parts of the interview to be included in the final cut, as well as adjust the brightness, color, and relative volumes of the interviewer and interviewee.</p> <p>Homepage: <a class="reference external" href="https://initialview.com">https://initialview.com</a></p>DjangoJavaScriptPythonVuehttps://problog.stephentpollard.com/posts/initialview/Tue, 04 Jan 2022 07:00:00 GMThttps://problog.stephentpollard.com/posts/sway/Stephen Pollard<p>2019 - 2021</p> <p>The main goal of Sway is to create a double-sided marketplace for content creators and brands to meet and execute contracts. I worked as the CTO and I was responsible for building and maintaining the full stack. I outsourced designs for the app then built the entire app using Meteor.js and Meteor-Kitchen. I took the app from prototype to final product and a soft launch with around 200 real customers.</p> <p>Homepage: <a class="reference external" href="https://sway.stephentpollard.com">https://sway.stephentpollard.com</a></p>JavaScriptMeteor.jshttps://problog.stephentpollard.com/posts/sway/Tue, 04 Jan 2022 07:00:00 GMThttps://problog.stephentpollard.com/posts/cdmcmc/Stephen Pollard<div><p>2015-2017</p> <p>The Convergence-Divergence MCMC is a Markov chain Monte Carlo method used to fit a customized model of the expected distribution of the convergence, divergence, and distance between many different branches on a phylogenetic tree. The definition of a convergence between two branches is when there are two substitutions at the same site on the two branches to the same amino acid. For example, a substitution on branch #403 at site 14 from Alanine to Glutamine and a substitution on branch #586 at site 14 from Methionine to Glutamine would be a single convergence event between branches #403 and #586. If either of the substitutions above were to an amino acid other than Glutamine, the event would count as a divergence. The distance between the branches on a phylogenetic tree is calculated from the top (ancestor) of one branch, back in time to the most recent common ancestor, and down the top (ancestor) of the other branch.</p> <p><a href="https://problog.stephentpollard.com/posts/cdmcmc/">Read more…</a> (1 min remaining to read)</p></div>PerlPhylogeneticshttps://problog.stephentpollard.com/posts/cdmcmc/Thu, 28 Nov 2019 07:00:00 GMThttps://problog.stephentpollard.com/posts/perlmodules/Stephen Pollard<p>2012-2019</p> <p>A collection of Perl modules for phylogenetic analysis and statistical inference.</p> <p>Repository: <a class="reference external" href="https://publichg.stephentpollard.com/PerlModules">https://publichg.stephentpollard.com/PerlModules</a></p>PerlPhylogeneticshttps://problog.stephentpollard.com/posts/perlmodules/Thu, 28 Nov 2019 07:00:00 GMThttps://problog.stephentpollard.com/posts/coding-experience/Stephen Pollard<div><p>As a way to demonstrate my proficiency in different programming languages, I calculated the total number of lines of code per programming language from all the projects in my project repositories.

Most previous models either required the amino acid propensities to be unchanging with time or to only change at specific points on the tree. Although it is much more difficult to design and test a model that changes continuously, that was precisely the goal of this project.</p> <p><a href="https://problog.stephentpollard.com/posts/acceptability-model/">Read more…</a> (1 min remaining to read)</p></div>MCMCModellingPerlRhttps://problog.stephentpollard.com/posts/acceptability-model/Mon, 04 Nov 2019 07:00:00 GMThttps://problog.stephentpollard.com/posts/dota-support-timer/Stephen Pollard<div><p>I enjoy a computer game called <a class="reference external" href="https://problog.stephentpollard.com/posts/dota-support-timer/dota2.com">DotA</a>. You play against other people online. Once a game has started, it is good habit to do things in the game at certain times.

I wondered if this was true, and so I built an app to keep track of how long players take for their turns. I also included a websocket backend for syncing across clients, so that anyone in the group may use their smartphones to check their turn times.</p> <p><a href="https://problog.stephentpollard.com/posts/player-timer/">Read more…</a> (1 min remaining to read)</p></div>AngularJavaScriptWebSocketshttps://problog.stephentpollard.com/posts/player-timer/Mon, 04 Nov 2019 07:00:00 GMThttps://problog.stephentpollard.com/posts/plex/Stephen Pollard<div><p>2013 - 2018</p> <p>The goal of the Phylogenetics, Likelihood, Evolution and compleXity (PLEX) project is to develop a platform for testing complex models of evolution against large amounts of DNA sequence data. The goal is to make possible fitting to data more realistic models of evolution that were previously computationally impossible to test. This is achieved by using an advanced statistical technique known as Uniformization, which allows avoiding previously computationally expensive methods such as Spectral Decomposition of the evolutionary rate matrix. PLEX compares models in a Bayesian framework using Markov chain Monte Carlo (MCMC) anaylsis.</p> <p><a href="https://problog.stephentpollard.com/posts/plex/">Read more…</a> (1 min remaining to read)</p></div>CC++Data scienceMCMCMercurialModellingPerlRhttps://problog.stephentpollard.com/posts/plex/Mon, 04 Nov 2019 07:00:00 GMThttps://problog.stephentpollard.com/posts/volunteer-scheduling/Stephen Pollard<div><p>2017 - 2018</p> <p>The church I attend, <a class="reference external" href="https://problog.stephentpollard.com/posts/volunteer-scheduling/denverpres.org">Denver Presbyterian</a>, needed a web app to schedule volunteers for the English as a Second Language (ESL) class to help teach English to new refugees in the Denver area at <a class="reference external" href="https://problog.stephentpollard.com/posts/volunteer-scheduling/projectworthmore.org">Project Worthmore</a>. I had written a number web applications before, and so I offered to write one for them. The app allows users to volunteer see what classes still need helpers and to volunteer for classes. It emails users their updated schedule within 24 hours of signing up for a new class. I developed the scheduling app using Django and deployed it to the Google Compute Platform.</p> <p><a href="https://problog.stephentpollard.com/posts/volunteer-scheduling/">Read more…</a> (1 min remaining to read)</p></div>DjangoMercurialPythonhttps://problog.stephentpollard.com/posts/volunteer-scheduling/Mon, 04 Nov 2019 07:00:00 GMT
