Karim is 29 and has written PHP for five years at a consulting firm in Lyon. One morning a client offers him a direct contract at €480 a day, while his salary tops out at €3,100 gross a month. He wonders whether a computer programmer really earns more as a freelancer, and under what conditions.
A computer programmer writes, tests and maintains the code that runs software, websites and apps. The job exists as an employee role and as a freelance one, and wage portage lets you practise it independently while keeping employee status, a salary and social protection.
A computer programmer turns a need into working code, then tests and fixes it until the software does exactly what it's supposed to do. In practice, they receive specifications (written by an analyst, a product owner or the client), pick suitable structures, write functions, review colleagues' work and hunt bugs. A good share of the day goes into reading existing code rather than writing new code. Surprising? Not really, since most projects are applications that are several years old.
The word "programmer" now sounds a bit dated. Job ads say developer, but the two terms overlap heavily. The table below sorts out the vocabulary.
| Title | Usual scope | Autonomy |
|---|---|---|
| Programmer | Writes code from specifications that are already defined | Guided by a technical lead |
| Developer | Designs, codes, tests and ships a feature | Autonomous within their scope |
| Analyst-programmer | Analyses the business need, then codes it | Talks directly to users |
| Software engineer | Defines architecture and technical choices | Decides how the project is structured |
Titles change from one company to the next. Always read the job description before judging the label.
You become a computer programmer through one of three routes: a short degree in computing (a BTS SIO or a BUT in computer science), a coding school such as École 42 or a bootcamp, or self-teaching backed by a portfolio of real projects. Recruiters look first at what you've built. A tidy GitHub repository sometimes outweighs a line on your CV. Our guide to getting into IT without a degree lays out the steps for self-taught candidates, and the Onisep career profile lists the recognised programmes (in French).
On the technical side, one solid language is enough to start: Python, JavaScript, Java, PHP or C#. The right pick depends on your local market and the kind of project you're after. Our ranking of the most used programming languages in 2026 shows where demand sits. Add Git, SQL and the habit of writing tests, and you have the base of an employable profile.
Then there's AI. Code assistants speed up repetitive work, but they shift the value toward reviewing, design and understanding the need. The article on the impact of AI on developers digs into it.
Soft skills weigh as much as code. Explaining a technical choice to a client who doesn't code, estimating a deadline honestly and saying "I don't know yet" before promising anything: that's what separates a programmer people call back from the rest. As a freelancer, those habits decide how long contracts last. A happy client renews, refers you and accepts a rate increase more easily after six months.
A computer programmer's salary depends on experience, language and region, but it can never fall below the French minimum wage: €1,823.03 gross a month for 35 hours, since January 1, 2026. The figure is published on info.gouv.fr (in French). Above that floor, the gap widens fast between a junior outside Paris and a senior on a rare technology. For benchmarks by role, our overview of IT jobs and average salaries is a good start, and APEC publishes its own pay studies.
Now to freelancing, where the numbers are tricky. Karim bills €480 a day and works 18 days in the month: that's €8,640 in revenue. It looks huge. Except you have to subtract contributions, insurance, accounting, days without a contract and the paid leave nobody pays him. Revenue is never a salary. Weepo's wage portage simulator converts a daily rate into an estimated net salary, management fees included.
A programmer going freelance chooses between two main options: a micro-business or a company, where you handle everything yourself, and wage portage, where you invoice through a portage company that pays you a salary with unemployment and pension contributions. Portage removes the need to set up a structure, issue invoices and file returns. In exchange, the company takes management fees from your revenue.
The page on wage portage explains how it all works, the one for backend developers in portage (in French) speaks to these profiles, and the pay page (in French) breaks down the salary structure. Contribution rules are published on urssaf.fr. The two statuses don't always exclude each other: see our article on combining wage portage and auto-entrepreneur status. If you just want to see the offer, the Weepo home page walks you through it in a few minutes.
One thing to check before signing: the length of the contract and the client's payment delay. A programmer paid at 45 days needs to survive two months of cash flow. In portage, salary payments follow a monthly calendar set in the contract, which changes how you budget.
A programmer writes code from specifications. A developer also covers design, testing and deployment. In practice, companies use the second term almost everywhere.
No, no degree is required to practise. A BTS, a BUT or a school like 42 reassures recruiters, but a solid portfolio and shipped projects are enough to win contracts, especially as a freelancer.
It's possible, but risky. Clients expect autonomy and deliverable code without supervision, which usually comes after two or three years in a company. Wage portage secures the start, since you keep a salary and social protection.
Often yes on paper, rarely the same once costs, insurance and gaps between contracts are deducted. Always compare a net salary with a net income, never with revenue.
It replaces part of the repetitive tasks, not the profession. Understanding a fuzzy need, choosing between two architectures and reviewing generated code remain human skills in high demand.
