The 3 recurring problems when developing an application without business vision
Your developer delivers features... but doesn't understand your business model, your users, or how the app should generate revenue.
6 months late, budget exploded, and in the end an app that doesn't match what you had in mind.
Your product takes off... but your tech stack plateaus. Complete rebuild needed = time and money lost.
If you nodded while reading this, it's normal. The problem isn't technical: it's that you needed a strategic partner, not just an executor.

A website primarily presents static information, while a web application offers complex interactive functionality: data management, user authentication, business workflows, and admin interfaces. Web applications are designed to be scalable and can handle large amounts of data.
Cost varies based on complexity: a simple application starts at €5,000, a standard business application between €10,000 and €25,000, and complex SaaS solutions can reach €50,000 and above. I offer a free audit to precisely assess your needs.
I use a modern and performant stack: Vue.js 3 and Nuxt.js for the frontend, Node.js or Nest.js for the backend, TypeScript for code robustness, and PostgreSQL or MongoDB for databases. This stack guarantees performance, security and scalability.
Absolutely! I develop custom APIs and use connectors to integrate your application with your existing tools: CRM, ERP, payment solutions, marketing automation services, or any other business solution. Integration is planned from the design stage.
Security is integrated from conception: robust authentication, data encryption, protection against OWASP vulnerabilities, automatic backups, and security monitoring. I comply with GDPR standards and implement security best practices.
Yes, I architect applications for scalability: modular code, optimized database, elastic cloud infrastructure, and microservices architecture if necessary. Your application can grow with your business without a complete rebuild.
A cheaper developer delivers code. A strategic partner delivers a growth tool. The difference? I challenge your product vision, analyze your market, think ROI from conception. Result: you save on costly mistakes (6 months lost, rebuild needed, app that doesn't scale). The real cost is an app that doesn't perform.
2-week sprints with regular demos. You see progress in real-time via collaborative tools (Slack, Notion, GitHub). Weekly checkpoints for feedback and adjustments. Total transparency on progress, challenges, technical decisions. You're not a spectator, you're co-creator of your application.
That's exactly why I code with modular architecture. Adding features, integrating new services, or pivoting on certain aspects is simple and fast. Documented code, automated tests, and I remain available to support evolutions. Launch is just the beginning of the partnership.
