Software Development:

Organizational Development:

Project Management:


Recruiting: Defined roles, sourced candidates, developed interview process, interviewed candidates, hired, and let people go as needed. See process details.

Project Management: Defined project management process for the team. Lead most projects. Tracked progress. Broke tasks down to the smallest, deployable, valuable thing. Sponsored others in leading projects.

Software Development: Implemented many systems, such as scheduled tasks, delayed jobs, job-candidate matching, large-scale emailing across multiple email campaigns, chat, apply, job ingestion, candidate ingestion, click tracking, event management, and reporting.

Leadership: Owned technical vision. Aligned with business vision. Grew and down-scaled the team as necessary, even though it was painful.

Technical Lead / Senior Software Engineer

Architecture Guild: Helped form and contribute to a group of people from across the organization to standardize our architectural decisions. The initial work was focused on documenting what we had. Then we started working towards shifting some of our existing decisions to more consistent tools that matched current and desired skill sets, hiring markets, and optimal use cases.

Roles and Responsibilities: Drove an effort to document current roles and their responsibilities as well as career development levels and guidance.

Community Engagement: Facilitated the Chicago Ember.js meetup events in the office. Helped coordinate sending 7 people to EmberConf and share our experiences when come back. Ran Lunch & Learn events where we watched instructional videos (like an EmberMap series) and discussed them in the context of our own work.

Technical Lead / Senior Software Engineer

Working on an Ember-based internal framework team with a focus on enabling other teams to build accessible web applications. This team ships an Ember addon that's a collection of web accessible Ember components.

Accessibility: Built, tested, and fixed web accessible components that conform to the legal requirements and web standards. Worked with screen readers such as NVDA to ensure a good screen reading experience.

Community Building: Working to improve communication to client teams about the status of their defects, what we're working on, what we plan to work on, and what we've done. Building a community mindset around the core addon that emulates large open source projects, such as Ember itself.

Team Processes: Improving team development processes by relying on a strong Retrospective process to drive the rest of the change the team wants to do. Changes are very problem focused--what's the real issue we're trying to solve, what possible options are there to solve that problem, what are the pros/cons of each, and after we've chosen one, how do we know if it was successful.

Technical Lead / Senior Software Engineer

Worked to standardize project processes, code quality standards, and the performance review process.

Promoted learning and career development in the dev team through pairing, code review, and other feedback.

Developed a web scraping system in Node.js and a standardized cache layer using rails-api.
