New York City, New York, Us

I work in the Core Computing group as well as the Center for Computational Neuroscience. In my first role I support research across the Flatiron Institute (software and infrastructure aspects). In my second, I do programming, design software infrastructure, and join in research on connectomics, working on the species Megaphragma viggianii. In my third role, I do software maintenance (code improvements, CI, docs, testing) on an opensource calcium imaging project called CaImAn (see Githib). My work in this role encompasses a wide variety of responsibilities and sees me working with a lot of software on AWS as well as our clusters

SRE on the Bedrock team, which does Internal Release Engineering/Packaging and Platform Engineering at Dropbox. I was focused on Platform Engineering.Wrote/maintained the tooling around config management and deb-repo management. Primary code designer/reviewer for all CM code, including linters and build-chain integration. Played central role in a major OS migration and platform refactoring - led definition of platform features, managed actual migration, chased upstream bugs and wrote or integrated patches to fix. Contributed to automatic machine installer, internal machine database and software distribution systems. Assisted in varied systems tuning.Technologies used: Chef, Puppet, Python, AWS, Ubuntu, Go, IPMI, CI, Postgres, system linker

This was primarily a systems administration role with moderate and varied programming.I was on the team responsible for hardware and software infrastructure (partly in AWS, partly in machine rooms). We had full responsibility for many systems (such as our Jira install) and OS-to-configuration-management responsibility for many other systems (Chef). I wrote a fair amount of code to handle scaling problems with available tools, debugged code, handled operational concerns, and liased with other teams while documenting and developing best practices (e.g. "how do we deploy software"). After hours I had side projects for other teams in the company, where I wrote a diagnostic tool for our support team and contributed code for one of our storage engines (WiredTiger) and assisted with competitive analysis documents relating to other databases I have expertise in. I also taught introductory Python programming classes for other employees.Technologies used: AWS, Chef, Linux, MongoDB, Jira/Crowd, Java, Perl, Python, Ruby, MySQL, Go, Powershell, Docker

Brooklyn, Ny, Us

This was primarily an architecture research role with some systems administration and some programming.I joined to improve scalability for the software stacks we were using on our servers, tuning the kernel and network stack and evaluating and writing userland software. Outside of this, I participated more broadly in systems administration: capacity planning, doing machine room work, and writing puppet recipes. I also wrote tools to parse and automatically diagnose error logs we received from client software. I brought a number of new technologies into the company. Technologies used: Ganeti, Linux, OpenVPN, IPTables, Perl, Python, C, LUA, OpenVPN, Zabbix, nginx, HAProxy, Puppet, FreeBSD

Pittsburgh, Pa, Us

This was primarily a development/research role (building software that implemented a private cloud).Local lead developer in the cross-university Emulab networking testbed federation. Responsible for design and development of new software features (most notably addition of cross-site VPN features, improvements to event system) and extension of the emulab model for new kinds of clusters (large FPGAs+laptop, VPN-linked remote distributed systems on diverse/uncontrolled networks). Also responsible for local Emulab cluster and training grad students on its use for research. Managed technical aspects of the CMCL lab - purchase/configuration/maintenance of server hardware, systems administration of large numbers of machines, operating systems imaging, design of a new machine room, documentation. Technologies used: FreeBSD, Linux, Perl, Python, C, PHP, MySQL, OpenVPN, Apache, MediaWiki, GIT, SVN, CVS, git, Cisco.

This was a mixed neuropsychology research and systems administration role with programming as needed to assist with both.I performed fMRI-based neuropsychology research for the ACT-R group, assisting with the design of experiments, writing software to generate stimuli and otherwise programming the experiment, recruited subjects and ran them through the experiments, and did analysis and presentation of the results. This research was published in peer-reviewed journals.I was also responsible for the cluster on which we performed the experiments, evaluating and maintaining software on those systems and training people in their use. During my tenure in this role, I built and moved those systems into a machine room. I also maintained our research group's website and performed all other development and systems tasks needed for the group unrelated to our cognitive modeling software.Technologies used: Linux (servers), PostgreSQL, Perl, fMRI, E-Prime (Programming language for Psychology Experiments), Apache, MediaWiki, Matlab, MacOS and Windows (supporting desktops), CVS/Subversion, Cisco

Pittsburgh, Pa, Us

This was primarily a software development role with some limited systems administration.Responsible for programming in support of various research tasks relating to high-dimensional clustering and machine learning (code in C, Perl, and Java), code refactoring, automatic generation of cross-language bindings, SQL database layout/coding, software design, programming for the Java/Tomcat/Apache platform, some systems administration. Technologies used: Linux and OpenBSD (servers), PostgreSQL, C, Perl, Java, R, Matlab, Mathematica, Apache (CGI and mod_perl), CVS, Nagios
