Hey, I'm Zach

I'm an engineer, coder, data scientist, and outdoorsman who loves to tackle impossible problems. Throughout my life I've plunged headlong into parts unknown as I've explored analytics, modeling, web development, simulation, teaching, cancer treatment, cycling, and photography.

I graduated from UC Berkeley with a Master's Degree in Industrial Engineering and Operations Research in May of 2015 and have since been working at Deloitte leading the development of a web-based analysis engine relating contract structure to financial impact for an enterprise level contract management website.

In my free time, I'm often burried deep in a side project to learn something new and leverage the data surrounding my daily life, or I'm out exploring exciting places on foot or on a bike with my camera strapped to my backpack.

DeloitteData Analytics Consultant

July 2015 - Present

I joined Deloitte after graduating and was immediately drafted into an application development team based on my coding experience. I taught myself full-stack web development in ASP.NET using Visual Basic and dove into developing a comprehensive calculations engine exclusively provided in our contract storage, analysis, and reporting solution. When I couldn't stop dreaming in accounting, I took a break by creating multiple interactive visualizations to connect clients to their data, and I researched fire and forget, threaded methods to allow rapid recalculation and scenario based analysis of portfolio changes.

UC BerkeleyGraduate Student Instructor

August 2014 - May 2015

During my year in the accelerated Master's program at UC Berkeley, I helped teach and facilitate two separate classes. I loved teaching so much that I was actually excited to get up at the crack of dawn every Friday and lead my early morning lessons. The first course focused on discrete event simulation where I guided students through event graph modeling and sensitivity analysis using the software package SIGMA. The second course covered mathematical modeling and output analysis using Excel Solver.

BoeingQuality Systems Specialist Intern

May 2014 - August 2014

Before starting graduate school, I spent a summer working for Boeing at the final stop on the assembly line, the Everett Delivery Center. I crawled through all kinds of wide-body planes, saw the innumerable parts as they were assembled together, and redesigned workflows to enhance how those parts were tracked. I created automated, visual tools in Microsoft Access and Excel to improve identification of FAA controlled components and reduce vital reporting errors. Additionally, I worked on integrating RFID identification and tracking of parts into the production process.

AUTOLabResearcher

October 2012 - May 2014

The Laboratory for Automation Science and Engineering, lead by Ken Goldberg, is a research group focused on bringing automation and robotics into our daily lives. I contributed to a group investigating new systems of brachytherapy cancer treatment using optimized delivery channels in 3D printed, custom fitting molds placed around tumor areas.

CSGO Scraper & Rankings

I've had a long and mostly healthy obsession with the game Counter Strike: Global Offensive. Recently, I implemented a web scraper using Java and SQL to aggregate and store statistics on 18,000 professional matches from the site HLTV. This data is fed into an R based model that incorporates Elo rankings and additional match information to predict future outcomes. Further work will include additional input variables such as individual player performance and fractional rosters to improve prediction accuracy.

You can find more information about the project here.

ErgoDox

For my third mechanical keyboard (no, I don't have a problem), I mounted switches, soldered electrical components, and assembled a DIY kit of an ergonomic, split hand keyboard. This project was purely for fun and learning how to solder!

This Website

What started as a small side project to learn SVG and the web visualization package D3.js slowly morphed into the website you're viewing right now. Every day I found another fun thing to explore, like this depiction of my past work or the outdoors visualization below, until I thought I might as well turn my standalone projects into one cohesive site all about me. I'm excited to keep working on new projects with D3.js and my abundance of personal GPS logs and Counter Strike data.

You can find more information about the outdoors visualization below here.

CSGO Live Predictions

Speaking of my Counter Strke: Global Offensive addiction, during my year in graduate school I created a parser in Java that would read server logs from professional matches and convert the millions of lines of text into complex, usable inputs to a regression based model that predicts round by round victory probability. Perfect information of the game allowed me to incorporate precise inputs like accuracy, team economy, or utilization of support items over time into the R based model.

Here's a writeup of the project.

Mobility Simulation

For my Capstone Master's Project, I designed an event based simulation for the World Health Organization alongside Professor Lee Schruben to model and optimize the high-level behavior of various worldwide staffing algorithms. We devised multiple metrics and visualizations which I wrapped in an easy to use VBA Excel interface allowing the client to rapidly test new algorithms and compare results across simulations.

Here's the final report.

Dashboard for SONOS

During my last semester in undergrad, I led a group of five students in unifying and analyzing data across SONOS to create a dynamic, high-level dashboard. I also researched a modified Bass Diffusion model to increase demand forecasting above 90%.

Get on Board

Have you ever thought that boarding a plane is incredibly slow and inefficient? In my senior year, I led a group of five students to design and create an event based simulation that evaluated the overall speed and efficiency of various boarding algorithms.

Check out a presentation we made on the project.
