Custom business apps: CRM, ERP, client portals. Delivered in 3 to 6 months. The code is yours. AI built into your day-to-day.
01 · who_it_is_for
I mostly work with three profiles. If you’re not one of them, let’s talk anyway — I’ll tell you honestly whether I’m the right fit.
Your company does between €1M and €10M in revenue. Your team loses time juggling Excel, Notion, Trello, HubSpot, Drive and Pennylane. It still holds together, but you’re hitting the ceiling — and every extra month deepens the debt. You need one custom tool built for your business that replaces 60% of that patchwork.
Your app was built in Bubble in 2022-2024. Today it’s struggling: performance, technical debt, a tech team that refuses to touch it. You need to migrate to Next.js — without breaking production.
You’ve validated your idea, you have a first signed customer or a pre-seed round on the way. You need a solid MVP in 4-6 weeks, not a perfect product in 6 months.

Transparent fixed prices, milestoned deliverables. No hidden day rate, no surprise invoices.
For comparison. An off-the-shelf ERP like Salesforce + add-ons costs €30k–80k a year, recurring. An ERP build with me is a one-shot fixed price, paid once, and the code is yours. Fast break-even, independence for life. Freelance, agency or in-house: the full comparison →

Is your Bubble app buckling in production? I migrate it to Next.js + Supabase. A method proven on the catering ERP I run in production (a clean cut-over, all users switched in a single step). Feature-for-feature parity guaranteed, with data-model and performance improvements.
The detailed migration method →Best for
scale-ups whose Bubble app is blocking their scaling
Hesitant about committing €8k or more? First we spend 5 days scoping your project together. You walk away with a clear, costed plan and an honest recommendation — including if the best solution isn’t custom development.
Guarantee: The cost is 100% deducted from the engagement if we continue together. Otherwise, you walk away with an action plan any other provider can pick up — no lock-in.
Best for
founders validating an idea, founders on the fence, scale-ups wanting an independent audit
Tax benefit
I’m an accredited CII provider, no. 27009163, certified by the DRIEETS Île-de-France and valid through 2029. In practice: if you’re an SME, 20% of what you entrust to me on the design of an innovative product can be refunded by the French government through the Innovation Tax Credit (Crédit d’Impôt Innovation).
Eligibility depends on the innovative nature of the project and is confirmed with your chartered accountant. As an accredited provider, I supply the traceability evidence needed (specification, deliverables, time spent) to secure your claim.

Clients anonymised under agreement. My own products, I stand behind them — name and all.
A fast-growing SME orchestrating around 500 catering projects a year with about twenty people. At first, operations ran on Excel and Notion — but volume kept climbing, the team grew, and the scattered tools created double entry and missed details.
A retirement-advisory firm with a founder who’s an expert in her field, two advisers, four closers, and both B2B and B2C clients. The goal: consolidate the entire operation (video appointments, assessments, engagement letters, deliverables, payments, signatures) into a single tool — and embed AI at the heart of the work so management doesn’t hit a ceiling as the company grows..
On hold since 2025 — the learnings reinvested in my current engagements
People with intellectual disabilities (autism, neurodevelopmental and cognitive disorders) and their carers — families and professionals — coordinate daily life on paper: the care home’s handover notebook, a pictogram board, time-and-space cues that aren’t adapted. Information gets lost between the family, the facility and the multi-disciplinary teams..
Commercial launch coming soon — already used internally on my ERP engagements
Freelancers and small product teams juggling 3+ clients pay for Linear or Jira per seat and struggle to capture a UX bug: you need a screenshot tool, a ticketing tool, then a manual hand-off. Three tools for a single action..
04 · process
From the first conversation to go-live — no commitment, no surprises.
You walk me through your context. I tell you honestly whether I can help, whether I’m the right fit, and roughly what it might cost. If I’m not the right fit, I’ll point you to someone who is.
If you want to go further without committing to a full engagement, I spend 5 days on your project: an audit of where you stand today, a functional specification, a costed estimate, a recommended stack, and an honest recommendation on the best path forward (sometimes it isn’t custom development — and I’ll tell you).
We refine the scope together in Notion or Jira (your call). You see exactly what the fixed price covers, what it doesn’t, and what each option costs. The quote gets signed on Yousign when you’re ready — not before.
You follow progress in real time on Notion / Jira. Weekly check-in. Regular demos. Documentation as we go. 4 payment milestones (30% deposit at kick-off, 30% at mid-project, 30% at delivery, 10% at the end of the warranty).
Go-live. Team training (3 videos + 1 live session). 6-month bug warranty included. Beyond that: a Care Pack or new features handled case by case.
The legal side: as long as no quote is signed, you’re committed to nothing. Discovery and early conversations are 100% free.
05 · why_me
Why I build. How I build. What I won’t do.
Why I do it
I wanted what I did to mean something. Soulmate was born from the daily life of my younger brother — autistic and intellectually disabled, living in a care home — I wanted my family and the professional carers to have tools worthy of the task, in a health-and-social-care market that offers so few. 2.5 years carrying that product (KEDGE Entrepreneurial School incubation, Déclics Jeunes winner with the Fondation de France) taught me what a real human problem weighs in an under-resourced sector. Today I put that same drive at the service of other entrepreneurs.
How I build
From business scoping to deployment, I cover the whole chain, alone, never in a black box. You follow progress on Notion or Jira in real time, we hold a weekly check-in, documentation is delivered as we go, and the code is yours from signing — you can take the wheel with another team at any time, without renegotiating anything.
What I won’t do
I don’t start until the scope is set. I refuse to drag my clients into endless technical debt. When we sign, we know what we’re delivering, how long it takes, and what it costs. If you want to go further after delivery, we start a fresh follow-up project — not a vague extension. You always walk away with a working product that delivers value, from the very first milestone.

Freelance, agency or in-house? The comparison06 · stack
The stack choice depends on the project. I always start by framing the problem, never by imposing a tool.
Only worth reading if you’re technical. If you’re not a developer, this section won’t mean much to you — it’s just here to show your IT team that the house is solid. What matters for you: everything is modern, fast, and handled end to end by me.
07 · faq
If yours isn’t here, email me at hello@buildwithremy.com — I always reply.
I work alone on the vast majority of projects — that’s my edge: zero coordination cost, fast decisions, consistent quality. For engagements whose scope runs past 6 months, I can bring in a second developer to help. I can also slot into an existing tech team — I’ve done it before; I adapt to your processes and your tools.
A fixed price milestoned across 4 deliverables. Each approved milestone triggers the matching payment. You can stop at any point after a delivered milestone — no penalty, no obligation to continue. The GitHub repo is yours from signing, with read access for your team if you want it. Another developer can take over at any time thanks to the architecture docs delivered continuously.
An NDA signed before the first technical brief if you want one. Client data is never shared (Supabase EU, strict Postgres RLS, encrypted Vercel secrets). Private repo, access only for the people named in the contract. No client data is ever used to train my AI tools.
Off-the-shelf ERPs are designed for 80% of cases. If your business processes are the remaining 20%, you’ll spend more time forcing them to fit than actually using them. A custom ERP only makes sense if your business has a real specificity. I say it honestly during scoping: if Odoo or HubSpot covers 90% of your need, I’ll tell you and I won’t take the project.
From €25k (excl. VAT); most complete business ERPs land between €35k and €80k (excl. VAT) depending on complexity. Compared with an off-the-shelf ERP (Salesforce + add-ons = €30k–80k/year, recurring), the return on investment lands in 12-18 months.
The code is 100% yours. Private GitHub repo, rights assigned by contract, documentation handed over. You can take maintenance in-house or to another developer at any time.
The MVP Sprint (from €8k excl. VAT) is built for exactly that. 4 to 5 weeks, tight scope, a concrete delivery. It’s my most common entry point.
A bug-fixing warranty included for 6 months after delivery. Beyond that, two options depending on your need: a Care Pack (regular presence in days per month, ideal for the first 6 months post-launch) or a fixed price for new features, which I quote case by case. Since the code is yours, you can also take the wheel with your team or another developer at any time.
Mainly France and the French-speaking world. I can work remotely in English when the engagement warrants it. For full engagements (ERP), I prefer French-speaking clients for the quality of the scoping conversation.
