I design and build custom websites, mobile apps and AI tools, from first idea to launch. Clear interfaces for your users, solid code for you.
AI engineer at Thales Alenia Space today, previously at Capgemini Engineering and Siemens. Freelancing since 2023.
Available for new projectsCoding at night too?
Starting points
Three crafts, one standard: a product that genuinely serves your users. AI isn't a gimmick here, it's my day job as an engineer.
My speciality
Tools that read, sort, predict and answer for you, plugged into your own data.
In practice
Technologies
For example: an internal assistant that finds the right procedure in two seconds.
Freelance AI engineerFast websites that rank well, and business apps shaped around the way you actually work.
In practice
Technologies
For example: a back office that replaces three spreadsheets and a binder.
Web developer in ToulouseiOS and Android apps your customers keep on their home screen.
In practice
Technologies
For example: a loyalty card that never gets lost at the bottom of a wallet again.
Mobile app developerA need that mixes all three, or fits none of them? Describe it in a few words.
No black box: you watch your product take shape at every step.
A first, no-commitment conversation to understand your needs, your users and your constraints.
A clear scope, a mockup and a detailed quote. You know what you pay for and what you get.
Development moves in short steps, with a version to try out regularly. Your feedback steers what comes next.
Deployment, onboarding for your team, then maintenance and new features if you want them.
A selection of personal, academic and open-source projects. Client work stays confidential, but I'm happy to talk about it in person.
AI & cybersecurity
A fictional bank that takes a cyberattack, detects it, heals itself and writes its own incident report with a local LLM and a team of AI agents. Team project from the Master's workshop at EPSI.
Private repository
AI & vision
An AI floor-plan segmentation tool: it detects the rooms on industrial plans and computes their area automatically.
Mobile app
The second version of the E-thana platform: a native Android app written in Kotlin.
Other projects
Web & AI
The site you're reading: server-rendered with Next.js, a built-in AI assistant, a 3D robot loaded on demand and a few secrets.
Web
A JavaScript chatbot with real-time conversation and an interface that adapts to every screen.
AI & game
Real-time Tetris where a human player goes head to head with an AI that makes its moves live.
Architecture
A Master's workshop on advanced TypeScript and software architecture.
The rest of my public code lives on GitHub (opens in a new tab).
Space, industry, consulting, public sector and freelance: I learned to ship reliable software where mistakes are expensive.
I'm Aymeric Mas. An apprentice AI engineer at Thales Alenia Space in Toulouse, working on satellite communications, and a Master's student in AI & Data Science at EPSI Toulouse, I've also been freelancing since 2023 for companies that want a custom digital product: a website, a mobile app or an artificial intelligence solution.
Master's in AI & Data Science

B3 AI Developer
Bachelor's-level year in artificial intelligence development
EPSI Toulouse, 1 year

And the next line? Your project, perhaps.
Let's talkOngoing
Thales Alenia Space, Toulouse
Artificial intelligence for satellite communications, at one of Europe's major space companies.
Capgemini Engineering
Designing critical AI solutions for strategic sectors, with sensitive data and strict security constraints. Deploying robust, scalable intelligent architectures.
Ongoing
Self-employed
Websites, mobile apps and custom tools for companies in Toulouse and beyond. Technical audits, consulting and hands-on support for digital projects.
Siemens
Bringing AI into critical industrial infrastructure. Process optimisation and predictive solutions for industry.
Sitcom Software
Lead developer on a native Android app: modern architecture, performance work and ownership of the full project lifecycle.
SDIS 11 (Aude fire and rescue service)
Modernising the digital infrastructure of emergency services: a secure intranet for logistics and accounting, sensitive data and GDPR compliance.
French departmental public security directorate
Building and maintaining intranet tools for the French National Police in a high-security environment. Network administration and access management.
Answers to what people ask me most often before we start.
It depends on the scope: a showcase website and a business app with AI don't have the same budget. After a first conversation, I send you a detailed quote with no surprises.
From a few days to a few weeks, depending on the project. I take on freelance work alongside my engineering job and my studies, so we agree on a realistic schedule together, in the quote.
I'm based in Toulouse and happy to travel around Occitanie, but I also work remotely with clients all over France and abroad, in French or English.
Not at all. I turn your needs into a solution and explain every choice in plain words. You keep control of the decisions, I take care of the rest.
Yes. An assistant that reads your documents, automating one task, analysing your data: AI can often plug into what you already have without rebuilding everything.
I stay available for maintenance, security updates and new features. The code belongs to you, and it's documented.
Yes, 9 in total. To get started, open the hidden terminal with the ` key (² on an AZERTY keyboard) and type “secrets”.
Another question?
Ask my AI assistant: it knows my background and my services, and answers right away.
Tell me what you want to build. I read and answer every message myself.
