Multi-tenant CRM platform
engineered for Kontaly.
We designed and delivered a secure, high-performance sales CRM and admin platform. Built with Next.js, React, Docker, and PostgreSQL on Linux infrastructure, featuring robust tenant isolation.
SaaS Architecture
The Multi-Tenant Core
To support Kontaly’s scaling SaaS model, we established an architecture that guarantees data segregation, low latency, and ease of deployment.
Dynamic Subdomain Routing
Next.js middleware inspects incoming requests, resolving the tenant identifier from the host headers (e.g. tenant.kontaly.com) and rewriting routes internally with zero client-side redirection overhead.
Type-Safe React CRM
A responsive customer relationship dashboard built in React. Leverages state management, optimistic UI updates for sales pipelines, and high-performance charts rendering thousands of client leads.
Isolated PostgreSQL Schema
Data segregation using a shared database with Tenant ID column partitioning. Row-Level Security (RLS) policies enforce database isolation, preventing accidental cross-tenant data leaks.
Dockerized Linux Environments
Containerized builds of the Next.js servers and background task workers. Automated deployment via Docker Compose on hardened Linux hosts, secured behind a reverse proxy.
Implementation
Scaling Tenant Operations
Kontaly required a centralized admin console and a client-facing CRM that could scale to hundreds of concurrent businesses (tenants). The legacy system suffered from database bottlenecks and lacked a unified administrative dashboard.
By migrating the architecture to Next.js and React, we created a single unified codebase that dynamically renders customized workspaces per tenant, significantly reducing software maintenance overhead.
Key Engineering Initiatives
- Dynamic Connection Pooling: Optimized PostgreSQL query throughput using pgBouncer connection pooling, allowing the database to comfortably scale alongside tenant growth.
- Role-Based Access Control (RBAC): Integrated an authorization matrix separating administrators, account managers, and sales representatives with strict middleware validation.
- Docker Orchestration: Created isolated container environments to simplify deployment processes, run migrations safely, and facilitate localized testing for engineers.
