• Promote effective processes, maintainable design, automated testing, and observability in a client's web-based system:
• Developed framework to enable monitoring with Sentry.
• Developed tools and process to load-test back-end data ingestion.
• Migrate in-house framework to Python.
• Hire additional team members.

• Develop back-end web tools and endpoints in a high-availability distributed environment, using OO Perl, AWS, Docker, Prometheus, Airflow.
• Migrated legacy data model to use a feed-downloader microservice, and developed an API endpoint to support the JavaScript front-end.
• Maintained cron and monitoring tasks, and migrated them to Docker.
• Developed history-archiver framework to permanently archive opt-in/opt-out history in a third-party service.
• Gave a talk on how to succeed in remote, distributed development teams, for the COVID-19 emergency of 2020.

• Multiple projects using Modern Perl in a geographically distributed Agile (Scrum) team, using Model-View-Template frameworks like Catalyst and PerlDancer, ORM data-access layer, SQL, HTML, CSS, and JavaScript.
• Led Agile team on multiple projects.
• Designed top-level architectural modules.
• Co-authored version-control and branching procedures, test guidelines, and marketing strategy.

• Enhance controlled-trial randomization software for the MGH Biostatistics Center.
• Managed the project and served as Scrum Master.
• Implemented an authenticated REST endpoint to generate a CSV-format dump of randomizations, another feature that persists randomization parameters in the appropriate HTML form, and a validation architecture for entered.
• Refactored inline JSON code into a data-model layer.

• Onboard new clients into order workflow system, and develop new features to that end. Written in Perl, using Moose, Catalyst, DBIx::Class (ORM) interfacing to PostgreSQL, also RabbitMQ.
• Developed a client-provisioning subsystem, to ease configuring client parameters after they are collected by BAs. Implemented using an ETL schema, making it easily extensible and generalizable to other configurable.
• Developed a fixed-field formatting framework, easily configurable for a wide variety of output formats.
• Co-authored team version-control and branching procedures using Git and Stash/Bitbucket, and test guidelines using Test::Class.

• Improve test coverage on 1990’s-era legacy CGI scripts, as a first step to refactoring the architecture.
• Developed black-box tests of legacy CGI scripts, using Test::Class and Test::WWW::Mechanize::CGI.
• Tracked test coverage with Devel::Cover.

Back-end Perl for multiple clients, including Shopzilla and Ticketmaster. Some front-end JavaScript as well.

CIDC needed a web service back-end that would collect user account and marketing data from sales affiliates of their online gaming service. We delivered to them a web service, built on Apache, Plack, and Dancer, which interfaced to their Informix database storage via RoseDB ORM. We also delivered a sample client application, to help their affiliates.

Enhanced the data-feed processing: to use more modern web services instead of direct database or flat-file data sources; and a typical legacy application enhancement, expansion of an ID field to use a larger data type to avoid running out of digits; and other enhancements. This tool processes many gigabytes of data per day, uses a map-reduce parallel.

Developed part of the advertiser account-management application, which used a Perl back-end (RoseDB, Combust) on top of MySQL, with ExtJS (AJAX framework) on the front-end. Also developed unit tests for the JavaScript UI code that executed on the development server using the Seamonkey JavaScript engine wrapped by a Perl module, and driven using the same.

Ticketmaster was developing a web-based workflow application to coordinate events and ticket sales between numerous stakeholders. The application used a Perl back-end (Combust MVC framework) on top of MySQL via Class::DBI ORM, and on the front-end, a substantial (10K LOC) client-side application, built on a custom JavaScript/AJAX framework, with some YUI.
