Primary Capacities

Specialities and Experiences

Software Architect

I produce creative, reusable solutions with solid documentation and an eye towards patterns and best practice.

  • core strength in data structures, algorithms, and object-oriented software design
  • experience constructing large projects with heavy resource requirements
  • practice interoperating with other protocols in the wild
  • drafting of technical specifications and test plans
  • construction of work delegation logic for high-efficiency threading and synchronization
  • performance profiling and targeted optimization

Web Designer

I enjoy composing graceful interfaces to online assets.

  • composition of UI using html, css (including generated, i.e. lesscss), javascript, AJAX
  • production of interactively generated content with multiple languages and web frameworks, both clientside and serverside.
  • deep working familiarity with W3C standards young and old alike, as well as proprietary browser extensions
  • familiar with threats in the browsable web (i.e. XSRF, XSS, SQL injection, etc) and defenses

Security Engineer

I am fascinated by the power and the challenge in distributed systems, and maintaining the security goals and reliability of services and infrastructure as business moves towards the cloud.

  • implementation of planned security boundaries, defense in depth, and applying principles of least privilege
  • application security: defensive programming, input validation, fail-safe design
  • cryptographic protocols: key management, protocol analysis, service deployment

System Administration

I demand stability from the technology I use every day.

  • expertise administrating Linux systems (primarily Ubuntu / Debian; also CentOS / Red Hat)
  • deployment of virtualization from full VM to lightweight cgroups-based containers to speed development iteration and ease system administration
  • preparation of init scripts to automate startup and provisioning scripts to regularize management of core services
  • administration of software RAID configurations, SQL databases, automated backup solutions, etc.

I like uniting these skills to produce and deploy high-performance software that can be accessible anywhere, reliably. My work has been referred to as "bulletproof", and I take pride in that.

I have a particular interest in applying myself to designing securely distributed high-reliability services that create value by resolving privacy questions in an increasingly networked world.

work experience

Echobit
software engineer
Jan 2013—April 2013
  • revamped a database with throughput issues to cache components of common queries in redis, increasing our supportable user count by an order of magnitude
  • built redis library integrating with company conventions and thread pool / event dispatch structures
  • created new UI features, from a DSL for dynamic news stories to client features structured as jQuery plugins
  • produced internal admin tools and analytics presentation system
  • updated legacy software to build in a consistent gem+bundler environment
Greystripe Mobile Advertising
software engineer
Oct 2011—Dec 2012
  • wrote and maintained software handling user requests on the scale of tens of millions every hour, and responsible for hundreds of thousands per day in revenue.
  • replaced aging systems that could not cope with the company's growing scale with solutions leveraging concurrent processing and distributed nonrelational data storage.
  • streamlined and automated build processes, increasing productivity for the entire server engineering team and raising the bar for quality control.
  • wrote enhancements to company internal software ranging from resolving user interface bugs to adding new APIs to interface with business partners.
  • optimized SQL queries and table layout for enhanced performance.
  • handled "big data" and Hadoop clusters.
  • responded to alerts and delivered fixes to live production issues.
  • participated in migrating company systems from Amazon cloud services into a private datacenter.
Security & Cryptography Lab
researcher
University of Minnesota
fall 2008—summer 2011
Advisors: Nicholas Hopper, Yongdae Kim
  • collected extensive experience in reading and synthesizing knowledge from academic publications, as well as drafting new scientific writing.
  • contributed to leading research in secure distributed systems for both communication and provably reliable storage.
  • administrated lab systems and servers.
Membership Concealing Overlay Network (MCON) Simulator
  • materialized extensive, functional cryptographic protocols.
  • constructed a large network simulation in Java with heavy resource requirements (handles hundreds of millions of messages across tens of thousands of links) and concurrent work delegation battle-tested up to 12 cores.
  • produced graphical interpretations of data using Gnuplot, including automated scripting to produce graphical interpretations on the fly for generated data.
BitTorrent Swarm Tracking
  • interacted with protocols of both BitTorrent clients and trackers in the wild.
  • optimized network operations for collecting data from tens of thousands of machines simultaneously.
Asprox Honeypot
  • observed network activity of malicious code.
  • handled decompilation of viral infection vectors in javascript.
Wright Biology Lab
researcher
University of Minnesota
Summer 2008
Advisor: Robin Wright
  • researched metabolic pathways for sterol production in genetically altered yeast — sequenced ribosomal genes, used sequence alignment tools and genetic databases to synthesize data, etc.
  • organized group of student researchers and coordinated data gathering.
  • gained experience in interdisciplinary communication.
Independent Projects & Open Source Collaboration
Siphon
  • utility for hosting processes in a psuedoterminal, then attaching to them from other terminals. Works over sockets. Extremly helpful in managing container systems such as docker.
Flatsite
  • dead-simple templating system in under 200 SLOC. Uses golang templates.
AHSlib
  • an open-source library of reusable Java tools for rapid development of applications utilizing networking, serialization/persistence, high-performance concurrency control, and thread scheduling.
Beard
  • Beard conceals a sleek java core under a scruffy guise of an HTML5/CSS3/JS web-2.whatever app. It makes it possible to ship something to run both in a browser (powered by an applet and allowing powerful client-side computation) or a as standalone desktop program using the exact same UI.
Gosh
  • process launching in golang, sporting a shell-script-like interface, plus substantial improvements on thread friendliness over go builtins.
MDM
  • MDM (Modern Dependency Management) tackles the problem of dependencies in software development by wielding advanced git features to provide strongly versioned and guaranteed repeatable builds, while still maintaining a repository that doesn't bloat over time. While the design pattern itself can be implemented manually with nothing but git and diligence, there's also a python program to make things easy and consistent.
CraftBook
  • a server-side modification to the popular creative game Minecraft; I'm one of the top three contributors.
  • vibrant collaborative community — 47 forks on Github at the time of writing.
  • large user base demanding backwards compatibility (over 75K downloads for the latest release).
  • requires agile development practices to match a rapidly advancing platform.
