Custom Web Application & SaaS Development

Off-the-shelf software works up to a point; but as business processes grow more complex or scale increases, the limits of these tools emerge. Workflows that cannot be customized, reporting screens that do not serve your needs, and monthly license fees that keep climbing gradually shift you from a position where the software works for you to one where you must make your processes work for the software. The silent but most costly consequence is loss of control over your data.

Our Solution Approach

We develop web applications and SaaS platforms designed to fit your business’s needs precisely. The process begins with user stories, data flow diagrams, and technical architecture design — the entire system is laid out on paper and approved before a single line of code is written. On the frontend, fast and maintainable interfaces are built with React.js and TypeScript; on the backend, REST API or GraphQL is delivered with Node.js; and a solid relational foundation is built with PostgreSQL in the database layer. Infrastructure is deployed on Docker and Cloudflare.

Scope & Features

• Multi-tenant architecture — A multi-tenancy structure where each customer’s data is kept isolated from others; serving dozens of companies simultaneously with no risk of data leakage
• Role and permission management — Layered access control with roles such as super admin, tenant admin, manager, and standard user; each role only accesses the areas it is authorized for
• Subscription and payment system — Plan management, automatic renewal, payment status tracking and invoice generation
• Audit log — Who did what, when; all critical operations are recorded in a traceable and exportable log
• API-first design — Ready REST API or GraphQL API for mobile app, third-party integration, or future expansion
• Advanced reporting and dashboard — Business-specific metrics, filterable tables, and exportable reports
• Notification infrastructure — Delivering system events to relevant parties instantly via email, in-app notification, or webhook
• File management — Secure document upload and access control on Firebase Storage or S3

Technical Standards

Docker-based deployment and environment isolation (development, staging, production) are applied as standard across all SaaS projects. Database migration management and versioning are included in the process. Horizontal scaling and connection pool optimization for high user volume are planned into the architecture from the beginning. Custom web applications such as Senkora use the same modular foundation.

Who Is It For?

• Medium-to-large businesses pushing back on monthly SaaS license fees who want to regain control of their data
• Startups and software companies aiming to offer subscription-based software services to their own customers
• Organizations with industry-specific business processes who find that off-the-shelf tools cannot be adapted to those processes

Expected Outcomes

• Recurring SaaS license costs are eliminated or significantly reduced; the investment pays for itself in the medium term
• The team adapts the system to business processes rather than being dependent on a system to manage those processes
• Scalable infrastructure that does not degrade in performance as the user base grows
• Auditable, traceable transaction history meets corporate compliance and security requirements
