Request a quote for this serviceWhat is this solution about?
When off-the-shelf software no longer matches your exact operational needs or charges prohibitive monthly subscriptions, custom development provides a decisive competitive edge. Whether building an internal ERP, customer CRM, private client portal, or scalable SaaS platform, we engineer end-to-end web applications. Utilizing modern technologies (React, TypeScript, Tailwind CSS, Supabase, PostgreSQL with Row Level Security), we design resilient software built to scale with your growth. Beyond corporate tools, our capabilities also extend to interactive and creative web showcases, as shown by Bénin Immersif (interactive cultural experience) and Brunak Architecture (contemporary architectural showcase).

Frequently Asked Questions
How is the security of our business data guaranteed?
Security is paramount. We implement industry-leading standards: TLS/SSL encryption in transit, encryption at rest, Row Level Security (RLS) on all database tables, and bulletproof session management.
Who owns the intellectual property of the developed application?
You own 100% of the source code, database structure, and deployment assets. JoDev does not charge ongoing proprietary licensing fees.
Can the application scale and add new features in the future?
Yes. By relying on modular TypeScript components and structured database architectures, adding new features, roles, or third-party APIs is straightforward without rebuilding the core.
What are the typical ongoing cloud hosting costs?
We utilize managed cloud platforms (such as Supabase and Vercel) that offer generous free tiers, keeping initial operational costs low (often under $25/month) until high traffic volume is reached.
How long does it take to deliver an operational MVP?
For a targeted MVP or essential internal tool, development generally spans 4 to 8 weeks depending on business logic complexity.
Do you provide post-launch maintenance and support?
Yes. Following initial launch and warranty, we provide ongoing maintenance and service level agreements (SLAs) to guarantee uptime and smooth iterations.
