Architecture
Explicit code structure — boundaries, modules, where agents may or may not generate.
I orchestrate your SCALABLE delivery — iASSET workshop + agents in prod
Augmented delivery orchestrator @ JST6 · Founding Engineer at the quality gates
Former Scaleway engineer (6 years), 15 years in dev and infra. I no longer sell coding days: I run agentized pipelines (Claude, Cursor, …) under the iASSET framework — FinTech and MedTech rigor, zero vibe coding.
Exclusive Methodology
Transform AI into a technological iASSET.
Move beyond vibe coding. iASSET structures your agentized pipelines — from spec to prod.
[S]
Versioned spec
Typed contracts, machine-readable intent before execution.
[S]
Security
Explicit security points — auth, secrets, compliance — verified on the diff.
[E]
Human gates
Founding Engineer review before prod merge — still master, not be mastered.
[T]
Agentized CI
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.

How the workshop works
The goal isn't to 'do AI'. The goal is a workshop that ships — with a human at the controls, not on tickets.
Spec → Agent
- Versioned intent, typed interface contracts
- Machine-readable scope before execution
- Product priorities aligned with business
Agents → Code
- Claude, Cursor and specialized agents in parallel
- Context framed by repo and iASSET conventions
- Measurable velocity, not vibe coding
Gates → Prod
- Founding Engineer human review before merge
- CI/CD, tests, security, observability, costs
- Sovereign cloud deployment included
Why an iASSET workshop?
You're no longer buying human time. You're buying a reproducible delivery pipeline.

Frequently Asked Questions
To address objections before the call.
Isn't this just disguised vibe coding?
No. Agents produce, iASSET controls. Every merge goes through human gates: architecture review, tests, security, observability. I stay the orchestrator — not a spectator.
How many clients in parallel?
4 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.
How do you use LLMs without degrading quality?
Versioned spec → agents in sandbox → gates before prod. Pace increases because execution is parallelized, not because standards drop.
