Description

Have you identified opportunities around AI but don't know what to build or how to put it into production? I can guide you from idea to deployment.

I help startups, SMEs, and product teams transform ideas into value-creating products, automations, and AI solutions quickly.

I am involved in the entire product cycle:

🌟 SaaS MVPs and web products

🌟 Generative AI, AI agents, and intelligent workflows

🌟 Business process automation

🌟 Redesign and modernization of existing applications

🌟 Technical architecture and product guidance

I also help teams accelerate their development cycle using AI-augmented development tools: Specification Driven Development (SDD), AI workflows, assisted code generation and review, automated testing and documentation, specialized agents, and MCP server integration.

💡 My approach

Understand the business need, identify high-impact opportunities, and deliver usable solutions rapidly.

Before writing a line of code, I seek to answer three questions:

✔ What problem are we solving?

✔ What ROI can we expect?

✔ What is the fastest way to validate the idea?

🏗 Some achievements

• Over a year at Shopopop developing strategic features for co-shippers: biometric verification, delivery grouping, merchandise returns...

• End-to-end creation of a budget simulator covering all of Tibco's services.

• Redesign of an authentication infrastructure with Keycloak, 2FA, and MCP server.

• Development of user journeys and checkout funnels at OVHcloud.

Available for standalone interventions or to strengthen an existing team + training

Shopopop is a French company offering a collaborative delivery service (co-transportation).

👉 The principle is simple:
Customers do their shopping (often in supermarkets or stores).
Individuals called "co-shippers" pick up these groceries and deliver them on their usual route.
In exchange, they receive a small financial compensation.

As part of the Mobile team, with a team of two back-end developers and four iOS/Android developers, my mission was to implement all server-side evolutions for the mobile application using Node.js.

The architecture is microservices-based:
Payment (Stripe)
KYC (Onfido)
Communication - Marketing (Braze-Segment),
Deliveries - core business,
The mobile application and its flows.

Specific tasks?

Technical and architectural design of features
Migration of the payment system from Mangopay to Stripe
Refactoring of complete authentication with Keycloak (2FA)
Implementation of re-verification of identity with live motion
Implementation of a system allowing co-shippers to directly report a delivery to a store in case of recipient absence
Setting up a pooled delivery system enabling co-shippers to optimize their time, thanks to an intelligent delivery matching algorithm.

MCP server for non-tech users, facilitating the reading of internal APIs.

Development of complete web services for the mobile application
Development on the identity verification module (KYC & GDPR)
Migration of payment provider to Stripe.
Complete refactoring of authentication via Keycloak
Development of an MCP server to link the information system to an AI agent.

My expertise includes:

Backend development (Node.js, APIs, architecture)
Frontend (Vue.js, React, high-performance interfaces)
Projects from scratch, redesigns, and critical migrations

LOGISTICS AND SUPPLY CHAIN
July 2024 - July 2025 (1 year)
Saint-Aignan-Grandlieu, France
As part of a project for BPCE, in collaboration with TIBCO – a provider of solutions used by large corporations for business data management, integration, and operation – we transformed a complex budget simulator, originally in Excel, into a modern web application.

👉 The starting point:
A critical Excel tool, comprising about twenty tabs, centralizing numerous business rules related to service calculation. This system was difficult to maintain, not very scalable, and significantly limited user autonomy.

👉 The objective:
Create a web application enabling beneficiaries to estimate their budget autonomously, reliably, and with a fluid user experience.

My role

Within a team of 2 developers, I contributed to the project from end to end.

Stack: JavaScript / TypeScript, Vue.js, Node.js

Reverse engineering of business rules from Excel
Modeling and implementation of calculation logic
Development of a web interface in Vue.js
Structuring a maintainable frontend architecture
