About me

Hi, I'm David! Independent developer based in Paris, full remote. I've been coding for 15 years and building businesses for almost as long. I co-founded a mobile startup that reached 100,000 users before being acquired. Today I build products for clients and for myself, under the Jinious banner.

This blog is a space to share what I'm learning about code, about entrepreneurship, about what I'm going through, and to try to be useful, at my scale.

If something I write resonates, tell me. If something seems wrong or poorly worded, tell me too. That's how things move forward.

The simplest way: email. I personally answer every message within the week.

What I'm doing now

Last updated May 12, 2026

  • Launching davidmoothen.com — the blog you're reading.
  • Building Mariage SaaS (a wedding site builder with guest management).
  • Iterating on my daily AI workflow — Claude as right hand for code, docs and research.

Background in brief

2010–2016 — Early years as an independent developer. Web, mobile, lots of PHP, then JavaScript, then React. I learned by doing, I made mistakes, I learned, I started over.

2016–2023 — Co-founder and CTO of My Beauty Community, a mobile beauty community app. 7 years building from scratch, hiring, scaling the product to 100,000 active users and 4.6/5 on the stores. €200k raised, assets acquired. Stack: Flutter, Node.js, MongoDB, ElasticSearch, AWS.

2023–today — Independent through Jinious. Combined advisory and execution for founders and SMBs. SaaS rental platforms, redesigns, technical audits. Current stack: Next.js, NestJS, PostgreSQL, Tailwind. Since 2026, I've been learning to master and apply AI in my workflow.

What I'm building on the side

A few side-projects in progress or in ideation. Living list.

  • CV BuilderLive · open source

    Modern, open-source CV generator. Because a beautiful CV shouldn't cost a subscription.

  • Mariage SaaSIn progress

    Personalized wedding site in minutes: guests, RSVP, dashboard. For couples who want a beautiful site without the headache.

My tools

Usual technical stack

  • Next.js (App Router, Server Components)
  • NestJS for long-lived APIs
  • PostgreSQL + Prisma
  • Tailwind CSS for the front
  • Flutter when native mobile is required
  • TypeScript everywhere, strict

Hosting

  • DigitalOcean (App Platform, Managed Postgres, Spaces) — for simplicity.
  • Hetzner + Coolify — when cost matters more than management time.
  • Vercel — for pure Next.js front-ends.
