Analytics Service Improvement Report

Executive Summary

The analytics-service is a Kotlin/Spring Boot gRPC service serving KPI, trends, and entity data from ClickHouse/PostgreSQL. The API is its primary consumer. While the architecture is well-documented (CLAUDE.md is excellent), there are significant code quality issues: a monolithic main class, pervasive cross-service duplication, and inconsistent patterns.

1. Critical: AnalyticsService.kt is a God Class

Live Preview Mode for Markdown Editing

Problem

Current markdown file viewing requires toggling between "read" mode and "source text" mode, causing disorienting context loss. When editing a file, the view switches modes and scrolls to a different position.

Proposed Solution

Implement a live preview mode that displays rendered markdown while allowing inline editing, similar to Obsidian's live preview feature.

• https://www.tripadvisor.com/Restaurant_Review-g187785-d1034513-Reviews-Sorbillo-Naples_Province_of_Naples_Campania.html Top pizza place (top 5 are all same level) in Napoli. Among the cheapest and my personal favourite. Best pizza: Nonna carolina. With pesto.

• https://www.yelp.com/biz/antico-forno-attanasio-napoli Pastry place. They make "sfogliatella" which is very local (and super good). There's two kinds: "frolla" (my fav) and "riccia". I suggest you try both :D

Twitter was failing me badly so I quickly wrote down a random list of reasons why I think (of course, that's just my opinion) code challenges hurt diversity:

• A lot of people performed badly at exams at uni (or any other form of exam). I can correlate to this very well as I was getting really nervous when taking an exam. I think it's kinda of normal to see code challenges as an exam. I know of people that wouldn't apply because of this reason. After seeing a lot of bad usages of this hiring tool, I wouldn't apply in most cases either.
• I think it's safe to assume code challenges acts as a filter. All our hiring techinques do and that's fine. My "problem" with this one is that it brings a lot of false negatives. The challenge may be badly written, the person may not have the time to commit to it. And junior developers can get really scared by this.
• Code challenges are generally meant to hire the bar of seniority and I find that highly counterintuitive. Based on my experience, the more senior a person is,
