Show HN: I built a tool to summarize my work for performance reviews using GPT (github.com)

Like a lot of engineers, I found performance reviews painful—not the review itself, but writing the self-evaluation. I’d spend hours digging through Jira tickets and GitHub PRs just to remember what I worked on.

So I built ContribSync, a CLI tool that:

• Pulls assigned Jira tickets and merged GitHub PRs (within a time range).

• Feeds them into GPT-3.5 or GPT-4 via OpenAI API.

• Outputs a clean Markdown summary you can tweak and drop into your self-eval.

I’m learning Go as I build this, so it’s fully open-source and designed with a plugin-based architecture for adding more integrations (Slack is in progress, GitLab/Linear coming next).

I’d love feedback on:

• Whether this actually solves a real dev pain point

• Architecture/design feedback from Go devs

• Feature ideas that could make it truly valuable for teams
