Work Experience
===============
Stripe (https://stripe.com/)
Remote
Staff Engineer
January 2015 - June 2021
- Moved our CI infrastructure from a proprietary system to Jenkins. This
included rewriting the testing infrastructure of our main monolith to run
tests in parallel with process isolation to allow for better reproducibility
and the ability to scale out automatically to many worker machines. This was
able to reduce turnaround time for tests by over 80\%, and provided a path to
scaling out to more machines to keep test times down.
- Converted all of our internal infrastructure to use an installation of
Confidant (https://lyft.github.io/confidant/) for secrets storage and
distribution, giving us much more control over which people and machines had
access to our secrets.
- Implemented an authentication service in go which allowed users to sign
arbitrary data as their own identity in a way that machines could
independently verify. This allowed us to remove almost all use of GPG at
Stripe, which eliminated a large class of tooling issues related to
deployments.
- Contributed to importing all of our low level infrastructure which had
originally been set up via custom tooling (or by hand) into Terraform,
allowing us to (mostly) automate creation of new AWS accounts.
- Contributed to our rollout of Envoy for service-to-service communication,
giving us automatic, transparent mutual TLS for almost all internal traffic.
Additionally, used features provided by Envoy to implement a blue/green
deploy mechanism which greatly improved speed and reliability of deploys for
our critical services.
- Implemented a fleetwide service in go for running maintenance commands on
servers (running puppet, restarting services, etc), which reduced the time
needed for running these types of commands from several days in some cases to
under 5 minutes. Additionally, designed a secure protocol for these types of
actions which ensured that the end services would not perform any actions
without first ensuring that the request was logged in a separate secure
append-only logging system.
Infinity Interactive (https://iinteractive.com/)
Remote
Senior Programmer
February 2010 - August 2014
- Maintained a large, legacy codebase which handled employee engagement survey
registration and reporting for several large companies.
- Wrote and deployed many small websites for clients, using Perl and
Javascript.
- Developed and maintained various open source projects used in our client
work, including Moose and Plack (see below).
UIUC Hydrogeology Lab (https://www.gwb.com/)
Urbana, IL
Visiting Research Programmer
February 2006 - February 2010
- Worked on the Geochemists' Workbench, a geochemistry software suite written
in C++ and Tcl/Tk.
- Added support for several new image output formats including SVG and PDF, and
added features to existing ones, including adding font embedding support to
our PostScript output.
- Contributed to adding parallel processing support to several scientific
calculations, using OpenMP.
- Ported our calculation applications from Windows to Linux, to allow them to
be run on large supercomputing clusters.
- Implemented a testing framework for our calculation applications, using
Perl's Test::More.

Open Source
===========
A more complete list of my projects can be found on my website
(https://tozt.net/projects.html and https://git.tozt.net/). All of my personal
open source work is also available on GitHub (https://github.com/doy), and you
can also find my Rust open source work on crates.io
(https://crates.io/users/doy) and my Perl open source work on MetaCPAN
(https://metacpan.org/author/DOY).
nbsh (https://github.com/doy/nbsh): 2021 - present
I am currently developing an advanced new shell using Rust and Tokio which
integrates aspects of terminal multiplexers to provide a user experience
more similar to notebooks (such as Jupyter) than traditional shells.
rbw (https://github.com/doy/rbw): 2020 - present
I wrote and maintain rbw, an unofficial command-line client for the
Bitwarden password manager. rbw is written in Rust, and uses a background
agent (in a similar style to ssh-agent or gpg-agent) to keep credentials
persistently in memory.
Reply (https://github.com/doy/reply): 2013 - 2016
I wrote Reply, a lightweight and extensible REPL for Perl. It includes many
useful features such as tab completion and history support.
Dungeon Crawl Stone Soup (https://crawl.develz.org/): 2009 - 2016
I was a member of the development team for Dungeon Crawl Stone Soup, a
roguelike game written in C++ and Lua. I contributed several features to
the game and was also the release manager for the 0.6 release.
Plack (https://plackperl.org/): 2012 - 2013
I was a member of the core development team for PSGI and Plack, the
specification for Perl web server/application interaction (similar to
Python's WSGI and Ruby's Rack).
Perl (https://www.perl.org/): 2011 - 2013
I was the release manager for the 5.17.1 development release of Perl, and I
have also contributed many bug fixes. I was also a lead developer on the
p5-mop project, a prototype of a new object system for Perl.
Moose (https://metacpan.org/dist/Moose): 2009 - 2013
I was a member of the development team for Moose, which provides advanced
object orientation capabilities to Perl. I was also the release manager
from 2011 - 2012.
TAEB (https://taeb.github.io/): 2008 - 2011
I was one of the lead framework developers for TAEB, a Perl framework for
programmatic interaction with the game NetHack. I was also the primary
developer for the leading bot written with TAEB framework.
