Achievements:

• Ensured compliance of the company's logging practices with European privacy regulations (GDPR) - Ansible, Logstash, Elastic
• Designed and implemented rolling package upgrades for production servers (Ansible, Jenkins)

Achievements:

• Automated and otherwise improved management of Atlassian applications (Jira, Confluence, FishEye/Crucible, Bamboo).
• Implemented utility-scripts for internal tasks, such as generation of SSL-requests, etc.
• Designed network-wide implementation of Sensu monitoring system.
• Advised developers of internal tools on best practices.

Achievements:

• Designed and implemented (in C) a command-line utility for flushing Akamai's cache of the company's content.
• Researched and implemented (in C) a fast algorithm for checking, whether a given string contains one of the multitude of substrings.
• Employed the above string-matching algorithm in a custom Apache-module to quickly detect mobile-devices.
• Upgraded the company's FTP-server, adding the WebDAV functionality. Added sorting functionality to Apache's mod_ftp.
• Added custom function (in Ruby) to Puppet to help prevent multiple cron-jobs from firing at the same time.
• Developed (in C) a Varnish module to support Akamai's G2O authentication protocol.
• Created scaled Drupal-installations for some of the company's magazine titles.
• Fixed the Sybase back-end of Apache's apr-dbd.
• Implemented (in C) a plugin for MySQL to enable user-authentication against LDAP-servers
• Implemented (in Java) a custom plugin for corporate JIRA to auto-update certain fields based on business-rules
• Implemented (in PHP) custom scripts for migrating a variety of other issue-trackers into JIRA
• Customization (in Groovy) of Jenkins-jobs to dynamically populate menus for software developers
• Implemented (in Ruby, Python, and sh) several customized Icinga monitors (i.e. GlusterFS)
• Minor fixes for GlusterFS to help monitoring -- and packaging GlusterFS RPMs for internal use
• Migrated various services to AWS
• Implemented backups for all of the company's AWS Virtual Machines (EC2) onto S3 storage (using Amanda)
• Implemented JSON-parser for TCL in C (YACC) -- open source

Achievements:

• Re-wrote Murex processing script-running utility to provide clear reporting of errors (sh).
• Greatly increased the processing throughput of the installation by balancing the production's load across multiple servers.
• Wrote a program to manipulate prices and other data in Murex cache-pages based on the time of day, the securities' markets and other parameters (Tcl).
• Implemented periodic pricing of a variety of bonds against Bloomberg service (Java).
• Implemented periodic processing of CDS-curves against Bloomberg service (Java).
• Oversaw and helped facilitate the upgrade of the firm's Murex installation to a new version v3.1.13 (C).
• Helped design and implement a plugin to notify external software of price-updates arriving to Murex' RTBS (JavaScript, .net).
• Implemented processing of SuperDerivatives data and loading it into Murex at market closings (sh, Java, XML).
• Designed and implemented a web-based system for collecting sign-offs from various departments before commencing the End-of-Day procedure (Tcl for sending out notices, PHP for processing sign-off "clicks").
• Automated and reorganized the End-of-Day workflow to perform independent jobs in parallel and without human interaction.

Achievements:

• Analyzed and solved complex customer-specific network and operating system problems.
• Designed, developed, and built a centralized backup system for the Company's many Sybase databases; this consisted of Sybase backup-plugin, which allowed DUMPing to a central fast-CPU machine, where assembler-optimized zlib compresses the data for long-term storage, and a TCL-program to backup all changed databases from all known servers (C, Tcl/Tk/TclX).
• Participated in the design and implementation of the Python plug-in for the Company's application (C, Python).
• Conducted a comprehensive study comparing the company's own proprietary approach to parallelization with the industry standard PVM (C/C++, PVM).
• Upgraded the company's FTP server to offer Secure FTP and WebDAV (over SSL) to allow the customers to upload all kinds of data without resorting to shipping the sensitive materials on tapes or other media. This required modifying an existing Apache module for painless access control based on SSL-certificates.
• Trained and mentored customers' personnel in efficient deployment, maintenance, and monitoring of the Company's application.
• Configured Solaris, Linux, and FreeBSD servers to act as Kerberos-clients of the existing Active Directory servers.

Achievements:

• As a system administrator planned and set up the start-up's network, e-mail, web, backup, and domain name services.
• designed and set up the "single login" on the network, based on NIS and amd (automounter).
• As a software engineer designed the redundant and self-recovering storage system for the users' photos. The system consisted of a fleet of the "off the shelf" PCs running FreeBSD, with each file being stored on two different machines -- storage servers.
• Designed and developed the "Uploader" part of the system -- based on TclHTTPD -- which would handle the files as they are uploaded and push them to a randomly picked pair of the storage servers.
• Participated in design and implementation of the image processing core.
• Designed and participated in the implementation of the general purpose on-the-fly image processing server (Apache, Squid, mod_perl; C, Perl).

Achievements:

• Configured the fleet of previously standalone FreeBSD-based testbeds into a cluster using NFS, NIS, amd (sh).
• Set up backups for the testbeds (using Amanda).
• Simplified deployment of new versions of the in-house software to avoid complete reinstall of the Operating System (sh).
• Instituted user accounts on the FreeBSD-based hardware testbeds to simplify file-transfers and other mundane tasks (sh, Unix administration).
• Designed and implemented scripts for automated hardware testing to greatly reduce the amount of manual testing and increase test coverage. In addition to controlling the hardware under test, the scripts also controlled third-party hardware through serial port(s) to simulate phone calls and other signals.
