Architecture
Explicit code structure — boundaries, modules, where agents may or may not generate.
ROIMVP in prod in 30–45 days — without hiring a senior
≈ €75–105k saved over 10 monthsfrom €4,500/ month (≈ 1/3 of a fully loaded senior's cost)
Agents + iASSET gates · dev & cloud included · pipeline live in 1 week
JST6 · iASSET workshop
Every month without a pipeline means burned senior budget, growing debt, and a risk of vibe coding in prod. AEP seats are limited to 3 pipelines.
I no longer sell coding days. I run an agentized workshop iASSET: spec → agents → human gates → prod. Fit in 15 minutes: clear go / no-go.

Three situations we see on almost every team that wants to ship faster.
A senior hire = 2–4 months + €120–150k. Meanwhile the roadmap slips and opportunity cost climbs.
Code generated fast, without specs or gates: it ships… until the incident, the audit, or the rewrite.
Billed human time, uneven quality — you're still managing tickets instead of the product.
Waiting doesn't lower the risk — it consolidates it.
~€80k freelance or €120–150k full-time senior over 10 months, vs €45k for an AEP workshop (€4,500/month) with prod included.
Each client gets an isolated pipeline. No infinite waitlist: seats close when taken.
In FinTech / MedTech, every month without a frame (security, compliance, observability) makes catch-up more expensive.
A clear read on the pain — and a decision in 15 minutes.
4 questions to identify the right entry point and your iASSET fit.
1 / 4
Move beyond vibe coding. iASSET structures your agentized pipelines — from spec to prod.
Explicit code structure — boundaries, modules, where agents may or may not generate.
Typed contracts, machine-readable intent before execution.
Explicit security points — auth, secrets, compliance — verified on the diff.
Founding Engineer review before prod merge — still master, not be mastered.
Auto tests, AI cost/latency monitoring, reproducible pipeline.
Ensure the capitalization of your expertise rather than suffering a future legacy.
Still master, not be mastered.
10-month workshop subscription at €4,500/month: less meeting noise, effort concentrated into 1 protected day per week per client + instant communication. iASSET pipeline, agents (Google ADK, MCP, Claude, Cursor…), weekly Founding Engineer review and cloud prod included.
Discovery, plan, IaC, tested cutover — to Scaleway or a sovereign target. Complementary to AEP when the lever is infra.

The goal isn't to 'do AI'. The goal is a workshop that ships — with a human at the controls, not on tickets.
Product focus: I design and industrialize agents (ADK) and MCP servers — not just chat-generated code.
You're no longer buying human time. You're buying a reproducible delivery pipeline.
A starting price, a deliverable, a clear decision.

Human gates, cloud deployment, handover or hiring.
To address objections before the call.
No. Agents produce, iASSET controls. Every merge goes through human gates: architecture review, tests, security, observability. I stay the orchestrator — not a spectator.
3 AEP slots maximum. Each client gets an isolated pipeline. If your project isn't compatible (exotic stack, daily pair programming need), I'll say so at the fit audit.
Versioned spec → agents in sandbox → gates before prod. Pace increases because execution is parallelized, not because standards drop.
Yes. Beyond code delivery, I design agents with Google ADK and MCP servers to connect your APIs, docs and systems — under the same iASSET gates (security, traceability, human review).
Feedback from my clients and partners
"Jean Sébastien accompanied us in the development of our web & mobile application with brilliance. He was able to build the front and back architecture, secured for health data. I recommend him!"
John Djaffar
CEO Pictaderm
"Jean-Sébastien is an accomplished fullstack developer: front, back, and even devops with a real infrastructure sensitivity that allowed him to implement a solution close to the highest standards in terms of security for health data. Exceptionally efficient, he knows how to develop the first version of a project with a high level of autonomy and maximum efficiency."
Guillaume Lebourgeois
CTO
"Jean-Sébastien successfully led many projects within Scaleway. Passionate about development, he is a serious, pragmatic, versatile, and efficient developer. He is proactive in technical choices and problem-solving. In 2021, he took over the management of a team of 7 engineers within the IT department. He strongly contributed to their growth by sharing his experience and expertise in development."
