// what I take on

What a senior lead changes in three months

Leading a mobile squad

Architecture of the scope, code reviews, coaching developers, interface with product. At TF1, tech lead of a squad of four and stand-in product owner.

Migrations and native bridges

React Native upgrades, Kotlin and Swift bridges rewritten, new devices integrated. Done at PMU and TF1 (VegaOS).

Delivery pipeline

Unit and end-to-end tests, GitLab or Bitrise CI/CD, automated deployment to TestFlight and the stores. A release that no longer depends on one person.

Taking over an app in production

Audit of the code, crashes and release chain, then consolidation. The work done at Zeturf on a betting app in production.

Hiring and upskilling

Scorecards, technical interviews, onboarding and mentoring, so the team holds without me at the end of the engagement.

AI tooling for the team

MCP servers, development agents and automations set up on the job, with the guardrails that go with them.

// contexts

Where it works

Large companies and scale-ups organised in squads, with agile rituals in place
Regulated or high-traffic environments: media, gambling, mobility
React Native apps already in production, to evolve or stabilise
Subcontracting through a consultancy is fine, with a single intermediary

// frequently asked questions

Long-term engagements: your questions

On site or remote?

Both. Remote by default, with proven rituals (weekly demos, code visible continuously); on site or hybrid in the Paris area when the engagement requires it. The presence rhythm is agreed on the first call and written into the proposal.

Through a consultancy or directly?

Both. The contract is signed directly with DM Consulting SARL, or through a consultancy or umbrella company that brings the client. A single intermediary only: two-level chains are declined.

What is your daily rate?

On quote, depending on pace, duration and location. The range is shared on the first call and the written proposal arrives within 48 hours. For scale, the fractional CTO offer publishes a base daily rate of €800 excluding VAT.

When can you start?

Availability is shared on the first call, with a firm start date. Depending on the current engagement, count two to four weeks between agreement and the first day.

A long-term engagement to fill?

Thirty minutes to describe the context, the team and the calendar. I tell you honestly whether the profile fits, and you get a written proposal within 48 hours.
