# What problems does Cosine solve for engineering teams?

**Cosine helps engineering teams move faster by tackling the work that slows them down - from bug fixes and backlog cleanup to code migrations and documentation.** It acts as an autonomous teammate that handles the repetitive, non-differentiating tasks so developers can focus on building features that matter.

### How Cosine helps in practice

Most engineering leaders face the same problems:

* **Persistent backlogs**: Non-critical bugs, minor UI issues, or low-priority tickets often pile up and remain unresolved. Cosine can clear these backlogs by taking tickets directly from Jira, GitHub, or Slack and delivering tested pull requests. → [See what tasks Cosine can complete end-to-end](https://chatgpt.com/g/g-689e4f005f7481919723ce3614903467-cosine-salesperson/c/68dfea49-ecb8-8332-b7d9-420bf6dc4e81).
* **Slow cycle times**: Developers spend valuable time reproducing bugs, writing boilerplate code, or updating dependencies. Cosine shortens these loops by automating common fixes and updates, accelerating time-to-merge. → [Learn how Cosine’s agent loop works](https://chatgpt.com/g/g-689e4f005f7481919723ce3614903467-cosine-salesperson/c/68dfea49-ecb8-8332-b7d9-420bf6dc4e81).
* **Context-switching overhead**: Jumping between repos, docs, and tasks drains productivity. Cosine autonomously retrieves context, navigates codebases, and plans solutions without constant human prompting.
* **Technical debt and maintenance**: Many teams struggle to allocate time for refactoring or documentation. Cosine includes features like **AutoDoc**, which generates or updates documentation, and handles refactors that improve long-term maintainability.
* **Skill bottlenecks**: Legacy systems, niche frameworks, or under-documented services often require specialized knowledge. Cosine’s model is trained to handle unfamiliar codebases, and can even be fine-tuned on a company’s proprietary languages and standards.

### Real-world outcomes

* Teams using Cosine report **30–40% of backlogged issues resolved** that otherwise wouldn’t get touched.
* A financial institution used Cosine to accelerate a **cloud migration project**, cutting estimated timelines from a month to two weeks. → [Read more about deployment options](https://chatgpt.com/g/g-689e4f005f7481919723ce3614903467-cosine-salesperson/c/68dfea49-ecb8-8332-b7d9-420bf6dc4e81).
* Cosine’s own team has merged **1,700+ PRs since June** with the help of the agent, proving its ability to operate as the most productive “engineer” on the team.

### Why it matters

Cosine doesn’t replace engineers — it multiplies their impact. By handling repetitive, time-consuming, and low-leverage tasks, Cosine frees teams to focus on innovation, feature delivery, and solving hard technical problems.
