# How Nearfleet Slashed PR Cycle Times by 75% and Reclaimed 30 Hours a Week Using Optibot

NearFleet's distributed engineering team replaced manual trans-Atlantic peer reviews with Optibot — enabling faster shipping, calmer workflows, and 24/7 senior-level oversight across every time zone.

## Time Saved Per Week
**30 Hours**  
Reclaimed from manual PR backlogs — nearly a full work week returned to the team each week.

## Reduction in Review Time
**75%**  
Manual senior intervention dropped from 4 hours to just 1 hour per PR.

## Security & Compliance Catch
**99%**  
Identified PII leaks across 15,000 lines of code that had already slipped through QA.

### Testimonial

"We've cut our review times from 4 hours down to just 1, saving the team at least 30 hours every week. If PR reviews are your bottleneck, Optibot is a no-brainer."

— Simon Balkau  
Senior DevOps Engineering Manager, Nearfleet

## The Problem
### Timezone Friction and Senior Bottlenecks in a Distributed Team

Nearfleet's engineering team is geographically distributed, spanning from Central Europe to both coasts of the United States. This created a "relay race" workflow where the baton was constantly being dropped due to sleep schedules.

- The 24-hour wait — US-based junior engineers often waited a full day for European seniors to wake up
- Senior burnout — reviewers spent up to 12 hours a day clearing the global PR queue across their entire shift
- Repetitive friction — seniors spent excessive time pointing out obvious mistakes that should have been caught before the PR even reached review

## The Solution
### An AI "Senior Engineer" for a 24/7 Workflow

NearFleet integrated Optibot as the first line of defense. Rather than replacing humans, Optibot acted as an automated "second senior engineer" — providing immediate, high-context reviews regardless of which timezone the developer was in.

- **Closing the timezone gap**: Optibot reviews every PR at 2:00 AM. US-based juniors can fix issues before European seniors even wake up — shipping progresses overnight.
- **Human-readable summaries**: Optibot generates clean summaries of every PR, letting seniors understand the intent of a change instantly — no synchronous hand-off call needed.
- **Compliance at scale**: During a major 15,000-line refactor, Optibot identified PII leaks that had slipped past manual QA — preventing a major compliance breach in production.

## The Results
### 75% Faster PR Cycles, 30 Hours Reclaimed, and 99% PII Detection

By removing the "low-level friction" from the review process, NearFleet transformed their culture from one of waiting to one of building:

- 30 hours reclaimed every week — previously lost to manual review cycles and timezone hand-offs
- 75% faster PR reviews — total manual time per PR slashed from 4 hours to 1 hour
- Asynchronous velocity — juniors receive instant feedback; features move from submitted to merged without waiting
- Permanent security auditor — Optibot caught a 15,000-line PII leak that had already passed QA
- Cultural shift — juniors now use Optibot proactively to learn and self-correct before a senior ever sees the code
