Development studio · Fully remote
I’m Charles-Antoine Alba, a senior developer for more than ten years. I take your product from first idea to launch day: on my own, with a team of developers or with AI agents, depending on what the project needs. Either way, I make the calls, and nothing ships until I’ve read it.
What I do
Web and mobile apps, dashboards, intranets and extranets, design systems. Built in React and TypeScript, with clean code your team can pick up and keep growing without me.
An option when the project calls for it: I design the flows and screens in Figma, then build them myself. Already have a designer? I’ll work from their mockups.
I lead your developers: I set the architecture and the coding standards, review pull requests and help everyone get better. I did exactly that for four years at Signally, with five developers and a designer.
Bring a project, a spec or just an idea. I frame the need, design the architecture and set the rules. When it fits, AI agents speed up the execution, and I review and polish every piece before it ships. You get the speed without the mess.

How I work
At Signally I led five developers and a designer. Since 2023 I’ve worked with AI every day, first with Cursor, and for over a year now with Claude Code.
The agents are fast, but they don’t decide anything. I pin down the need, pick the architecture, set the standards, and I read every line before it goes live. AI makes me quicker, not sloppier, and it frees time for what usually gets cut: useful tests and clean documentation. For you, that means a project that moves fast, and one senior person accountable for the result.
You tell me about your idea, not just the spec. It’s free, and you leave with a concrete first direction: what’s doable, how, and where to start.
We choose the solution together. Then a clear scope and timeline, before any commitment.
Regular demos to watch it take shape, clean code, and a handover your team can pick up.
About
I trained at 42 and I’ve been a front-end developer and product designer ever since. I went independent in 2018, and by 2025 the work had grown enough to become a company: Variables.
The idea hasn’t changed: you work directly with the person who designs and builds your product. No middleman, no account manager rephrasing things, so nothing gets lost between what you ask for and what gets built. I work fully remotely, in English or in French.
“His technical expertise and grasp of UX turned our application into a smooth, appealing experience. Real talent, great responsiveness and professionalism. Deadlines were met, which is worth pointing out!”
“An excellent command of front-end technologies, and he saved us from a disaster after another freelancer let us down. Very available, even on weekends and late at night, he quickly made up the delay we were building up. Icing on the cake: he is great to work with and has a good sense of humour!”
“Very responsive in helping us scope the engagement precisely, and in carrying out the mission. Deadlines were fully respected, which mattered a lot to us.”

Tell me about your project and we’ll work out together how I can help. The first call is on me, and so is the advice.
