I will create a custom business management software
AndresCariola
About this gig
Transform your business operations with a custom enterprise software platform. I don't build generic templates; I create tailored management systems following software engineering best practices (Sommerville methodology) and international standards (PMBoK).
Why Choose Me? As a Civil Engineer turned Software Architect, I understand both complex operational workflows and technical requirements. Whether you need a construction management system (with EVM, CPM & Gantt), a legal case tracker, or a financial ERP, I build the software that adapts to you, not the other way around.
Core Features Included:
- Custom KPI Dashboards (Chart.js/Recharts)
- Advanced Role-Based Access Control (RBAC)
- Automated Document Generation (PDF/Excel exports)
- Real-time workflows, audit logs & notifications
- Multi-tenant architecture for scalability
Premium Tech Stack: Next.js 14, TypeScript, PostgreSQL / Firebase, Tailwind CSS, Vercel.
Perfect for companies outgrowing spreadsheets but not ready for prohibitively expensive SAP-level solutions.
Please message me before placing an order to discuss your exact requirements!

FAQ
How is this different from buying off-the-shelf software?
Custom software fits YOUR workflows, not the other way around. No monthly fees, full ownership, complete customization. Off-the-shelf solutions require you to adapt to them; I build the software that adapts to you.
What industries do you specialize in?
Construction, legal, healthcare, finance, and real estate are my primary domains. However, the architecture works for any business management need. My background as a Civil Engineer gives me unique insight into technical and operational requirements.
Can this integrate with our existing systems?
Yes! I can integrate with existing databases, third-party APIs, payment gateways, and legacy systems. I've built integrations with Firebase, PostgreSQL, MySQL, REST APIs, and more.
What about data migration?
I can help migrate data from spreadsheets, legacy systems, or other databases to your new platform. Migration planning is included in Standard and Premium packages.
Is the code maintainable?
Absolutely. Clean architecture, TypeScript throughout, comprehensive documentation, and following Sommerville software engineering principles. Any competent developer can take over if needed.
Can you add features later?
Yes! The architecture is designed for extension. We can add modules and features as your needs grow. Many clients start with the Basic package and expand over time.
What hosting do you recommend?
Vercel for frontend/API (excellent free tier), managed PostgreSQL (Supabase, Railway, or your own server). I handle deployment as part of the delivery.
Do you provide ongoing maintenance?
Premium package includes 90 days of support. Extended maintenance contracts are available. I also provide documentation so your team can handle routine maintenance.
What if we need mobile access?
The platform is fully responsive for mobile browsers. If you need native mobile apps, I can develop those separately or as an add-on to this project.
How do we handle sensitive data?
I follow security best practices: encrypted connections, environment variables for secrets, role-based access control, audit logging. For highly regulated industries, we can implement additional compliance measures.
