Roadside assistance for open source maintainers.


Project Liaison

Talk with the open source projects you depend on, and find out what they need to work better with you.

Expedited Release

Get the million little things done that stand between you and release, so those features sitting in git master can get to users who are waiting for them.

Developer Onboarding Audit and Revamp

Assess what's slowing down new engineers in documents, tooling, and training -- and fix it. (Example.)

Hackathon/Sprint Prep

Set up first-timer guidance, select TODOs that can actually get done, and get the right sessions on the schedule and make them effective.

Intern/Mentor Support

Prepare your project to apply for Google Summer of Code or Outreachy, and prepare for applicants to have an easier developer onboarding experience.

Initial Open Source Release

Triage, edit, and transfer bug reports, documentation, and TODO lists from your company's intranet to GitHub, GitLab, a wiki, etc.

Contributor Outreach

Bring in new coders, writers, and other volunteers -- and grow the ones you already know.

Grant Writing

Write and submit project plans and funding requests to get grants, and report to funders once you've got them.

About Changeset Consulting

Changeset provides short-term project management services to free and open source software projects. Does your team, or a project you depend on, need to get the next release out, write developer or user documentation, triage and respond to bugs, clean out the code review queue, or prioritize tasks for upcoming work? Changeset Consulting can do all that, so maintainers can focus on writing and reviewing code.

"Sumana Harihareswara, who is an extremely deep thinker (and with a blog to prove it), has started Changeset Consulting, to help people and companies manage their open source projects.

If you know a business that is struggling with managing its open source dependencies, they might be interested in hiring Changeset to make sure bugs get escalated and fixed, and new releases come out on a dependable cadence....

Sumana is a great person to work with."

Federico Mena-Quintero, co-founder of GNOME

"As a project manager, she made it natural and easy for members of the project to do their part well."

Dan Conner, developer and Behavior contractor

"If you hate bad meetings, you should talk to @ChangesetLLC.

I’ve walked away from every meeting run by @brainwane with a sense of awe and wonderment rather than crankiness and regret.

Efficient, painless, productive."

Ernest W. Durbin III, Python Package Index maintainer

"Whenever I wonder 'What has Sumana been up to lately', I see her working on some excellent new project, cleaning out a neglected backlog, organizing training materials, helping people start an event, documenting something undocumented, prodding WMF to get smarter -- in other words, she's been tirelessly, fearlessly, capably making things better for our dev community, which in turn benefits the quality of the software we build together."

Erik Möller, VP of Engineering and Product Development, Wikimedia Foundation

Pricing will vary per engagement; please contact Changeset for a free initial consultation and estimate.

Hourly work is available at a per-hour rate. Most engagements will take 20 or more hours and cost substantially less than the same work would on a per-hour basis.
