Simon Ronnes — Indie Developer

Indie developer

I'm Simon. I build apps and tools mostly for the fun of it — no ads, no dark patterns, no noise. Just software I'd want to use myself.

Apps

Spider

Classic Spider solitaire. No ads, ever.

Projects

The lab bench — the stuff I build for the joy of it: platforms, little tools, and half-finished experiments.

Northside Studio

My product studio — where the bigger builds happen.

KREIA

AI platform that audits knowledge bases — scoring every article, rewriting the weak ones, tracking quality over time.

Candor

An AI-first applicant tracking system, built natively on Salesforce.

Canonix

Turns dense documents — CAOs, legal, policy — into queryable knowledge with graph + vector retrieval.

Flow Mason

Linter, visualizer and optimizer for Salesforce Flows.

sf-navigator

A little browser tool for darting around Salesforce orgs without the endless click-through.

Where Is This Used

Free dependency explorer that answers “where is this used?” for any org.

sf-mirror

Metadata ingestion pipeline that makes big systems readable for AI agents.

OnTheWall

Scandinavian-inspired poster shop, print-on-demand from front to back.

Writing

Hello, world

Why this site exists, what I'm building, and what to expect here.

About

I'm Simon — a developer from the Netherlands who never quite clocks out. By day it's Salesforce and AI; by night it's whatever I feel like building.

It mostly started with my mom and a game of Spider solitaire — waiting through an ad after every single win. That annoyed me enough to build her a version without any of it, and I haven't really stopped since.

Almost everything here I made for the fun of it. No roadmap meetings, no growth targets — just me, a keyboard, and the small satisfaction of software that doesn't try to trick anyone. Want to say hi? Email me at simon@hdconsulting.nl.
