Freelance
Available for freelance work
Alongside my job, I take on a few focused freelance projects where I’m most useful: AI inside an existing product, mobile apps and custom web tools.
- /AApplied AI
AI inside your product
An assistant that answers from your documents and cites its sources, an agent that acts through tools, an MCP server that plugs your data into an assistant, image generation. Built into what you already have, with tracked costs and guardrails.
- /BMobile
iOS and mobile apps
An iPhone and Apple Watch app in native SwiftUI, or iOS and Android with React Native and Expo. From mockups to store release, including notifications, payments and sync.
Done before - /CCustom web
Custom web applications
Business tools, client portals, booking or application platforms: Next.js, React or Vue.js, a Symfony, Node.js or PHP back end, online payment. From specification to launch.
- /DSupport
Technical support and audits
Taking over an existing codebase, auditing an app before a new phase, laying a first AI building block or helping a team get started with it. Short engagements, remote.

How I work
- (01)Scoping
A 30-minute call to understand the need and see whether I’m the right person. Free, no commitment.
- (02)Proposal
A written scope and a quote, fixed-price or time-based, before any code is written.
- (03)Delivery
Short, regular deliveries on a test environment, so decisions are made on working software.
« Dimitri built our booking website and our app: online payment, deposits, calendar sync and a space for our property owners. He took the time to understand how a concierge business works before suggesting anything, and the tool is now part of our daily routine. »
