I designed and developed Brevipay as a Micro-SaaS focused on Cash Flow and Financing to address a classic but critical business challenge: waiting for customer payments.

Brevipay transforms term invoices (often 30-60 days) into immediate available cash through an automated and fully online invoice advance mechanism. This logic allows businesses to drastically improve their cash flow, without going through cumbersome or expensive banking procedures.

🛠 Applied Approach

🎯 ROI-oriented Product Scoping

Precise identification of business frictions related to payment delays in B2B operations.

Prioritization of features generating tangible impacts on user cash flow.

🏗️ Rapid Construction of a Usable MVP

Development of an operational MVP capable of managing:

Invoice import/export,

Invoice advance rules,

Cash flow simulations,

A simple and secure administration interface.

Rapid deployment to validate real-world usage before heavy investment.

🔁 Iteration & Continuous Learning

Collection of user feedback to refine financing rules, KPIs, and workflows.

Ability to pivot or enhance business modules based on market signals.

💡 Product Vision

Build a solution that sells or is used because it genuinely reduces financial stress, not just because it's "functional".

Transform an intuition of need (need for cash) into a scalable and structuring digital tool.

📌 Result & Value Created

Brevipay embodies my ability to:

Recognize a strong and recurring business need,

Translate this need into a viable digital solution,

Deliver a concrete SaaS product, not a mockup,

Generate measurable business value from the very first versions.

I designed and developed mes-marchés.com as a business Micro-SaaS aimed at solving a concrete problem: the chaotic, time-consuming, and poorly equipped management of public procurement on the operational side.

The objective was not to "create a complete platform," but to quickly validate the business value by building a usable MVP, focused on real-world uses and on-the-ground friction points.

Approach applied to the project:

Feature Engineering

Breaking down the business problem, eliminating the superfluous, and strictly prioritizing features that generate immediate gains (time, reliability, visibility).

MVP Construction Focused on Real Usage

Development of a product usable from the first versions, with rapid deployment to confront the tool with end-users.

Rapid Iteration & Feedback Loop

Continuous adjustment of features based on field feedback, with short cycles (48-72h) to maximize learning.

Modern Micro-SaaS Architecture

Stack focused on execution speed, scalability, and automation (auth, payments, APIs, business workflows).

This project illustrates my ability to:

Transform a complex process into a simple-to-use product

Build a viable business tool, not a demo

Arbitrate between technical quality, speed, and ROI

👉 This is exactly the approach I offer my clients today: validate a business, an internal tool, or a SaaS without losing months on over-engineering.
