Project Manager and Full-stack Software Engineer
- Added a number of features, including a drag-n-drop image uploader, a "pending" feature for group request submissions, a history search feature with full text indexing and fuzzy text search for stock items, Facebook-style homepage notifications, and more, to a purchase request system.
- Created a government extranet for inspectors to approve policy manual revisions.
- Enabled cache support for hangar floor parts, requiring fewer trips to the stockroom while maintaining government traceability requirements and supply-level monitoring.
- Fixed, cleaned up, and provided data recovery and performance tuning for ad-hoc databases. Generated a network attack tracker graph that automatically imports data from the router.
- Implemented several features, including a document hierarchy editor with drag-n-drop added to the CMS, a third-party issue tracker solution hosted with Docker, and cronjobs to help catch vendor errors and notify the relevant manager using an integrated permissions hierarchy.
- Made the core functionality of an intranet app robust against outages of the main third-party system.
- Ported PartTake from VB to mod_perl, including barcode and address printing (with provisions for just-in-time auto-switching printers on Windows via URL scheme and rundll32 workaround).
- Staged a build system with unit testing, minification, performance testing, and integration testing with integrated QA.
- Upgraded a backup system to cross-platform multi-server usage.
- Added a website section powered by third-party bulletin board software and created an automatic image renaming and uploading tool for personal project management.
- Built a power outage tracker graph that automatically imports data from UPS. Added authenticated inspection tracking to the alternative UI for shop order updates.
- Created a couple of backup systems, including a solution for HyperV environment and a backup, verification, and restore solution to replace the old tapes-based system.
- Designed, wrote, and maintained the PartTake software system to streamline stockroom processes while meeting strict government traceability requirements and working with the exisitng inventory system and its timeclock, tool tracking, and purchase ordering integrations. Shipped with barcode and address label printers drawing relevant data from the existing system and configured the GUI tool.
- Enabled vendor purchase email templating for the purchase request system.
- Implemented honors-system workstation sharing, allowing different logins on separate tabs without confusing credentials (see https://stackoverflow.com/a/1133999/16777 – sometimes the rather unique business environment involved required unorthodox solutions).
- Oversaw and helped with the data migration of an accounting, inventory, and shop order system from DOS to SQL/Windows.
- Redesigned a number of websites, including a website and corresponding script to automatically update local pilot weather information, and vectorized its company logo; a website and wrote/edited material for the Save the Airport local political campaign; a website to be fast-loading and able to fit on a floppy disk; a website to feature a new aircraft sales section; a website with dynamic content and search functionality; and a website with featured past projects and auto-updated weather map overlayed onto the company's precise location.
- Wrote and implemented IT policy and analyzed and made improvements to the year-end processes as well as researched, revised, and helped implement, organize, and conduct the company process audit.
- Built an NS- and IE-compatible website and corresponding Windows GUI page-text updater utility.
- Created marketing materials to sell PartTake to other users of our third-party niche industry integrated accounting system.
- Developed a custom CMS—from scratch—automatically following government regulation updates, notifying only the relevant internal parties of the relevant internal documents (and their internal dependencies) that would need review. All regulatory links were kept in consistent auto-updated format, and review and audit policies were enforced by database triggers.
- Evaluated Andromeda as a potential platform to base the rest of the intranet app on.
- Implemented the UI for a SQL backup manager. Rewrote an intranet app with commonly used SQL reports from scratch to speed it up and cover functionality gaps.
- Migrated a domain from Windows 2003 AD to Samba 4.
- Oversaw the migration of a server and workstation system from Novell Netware to Windows 2000 AD.
- Refactored shop order workflow to streamline usage, testing, and maintenance; integrated a fast menu UI library (both keyboard and touchscreen friendly).
- Built database development tools: a PostgreSQL function body searcher for global renames, a GraphViz-based foreign key map generator, and more.
- Created server health metrics via statistical process control graphs and output comparison, with email notification.
- Developed a smart-sorting table view UI so that part numbers end up being sorted as they traditionally were physically, even in more complicated number-letter-number-etc. scenarios.
- Expanded the shop order UI to cover more features than offered by the third-party system, and added project wrap-up verification tools to avoid peak activity errors.
- Integrated government-supplied aircraft registration databases for easy client info updates.
- Migrated a purchase request system from paper to email, and then later from email to database, integrated with the existing intranet app. Wrote a VB5 utility to speed up the process of scanning old documents into the new paperless system.
- Built the Dogfooded task/project management feature integrated with an intranet app.
- Created Widgetissimo, an initially jQuery-based plugin side project for UX improvement with form autosave and keyboardability focus.
- Developed an alternative UI for shop order updates for user convenience/workflow speed, including time tracker UI replacement, with RTF to HTML (and back) conversion, and HTML editor UI (cross-database).
- Integrated a timed training bulletin system with a CMS to force a re-read of updated sections at a manager-specified interval.
- Migrated a major accounting system version, including all required changes, to homegrown add-ons.
- Developed disaster recovery for SQL and filesystem data from a HyperV environment.
- Integrated a website with Blogger.com to allow a stockroom manager to update the special offers page herself.
- Researched, built, set up, and administered a new Linux server and dial-up connection sharing. Migrated the intranet app and scheduled scripts from Windows to Linux.
- Developed draggable sort-preserved multiselect for quick composition of complex selections for a purchasing request system (close emulation of Windows Explorer's behavior for easiest user learning curve).
- Integrated an avionics storage bin tracking and replacing paper system with the project management UI and vendor database.
- Mitigated potential disaster using commit hooks integrated with paper procedures to keep a plan for dealing effectively with IT service outages up to date. Wrote an intro paper telling how to access multiple automatic backups of electronic documentation.
- Researched, designed, and implemented autogenerated database views from a smart normalized database design with integrated benchmarking. The database features manager, employee, and personalized database views (where applicable) with auto-generated UI and tables that automatically link to the editing page for each row and the editing page for any referenced foreign key in the row. The editing pages saves partially filled-out forms to pre-emptively protect against data loss in the case of client, server, or connection problems.
- Developed full text search indexing for a third-party app via smart synchronization for vast speed improvements on zero budget.
- Integrated company role hierarchy with the CMS for training so that document updates trigger a notification to exactly the right employee to read changes; an automatic org chart generator is based on this data to fulfill a requirement for maintaining the policy manual.
- Integrated Selenium IDE into the QA process for most common tasks to prevent regressions.
