Smart Residential Ecosystem Platform

We built a scalable digital platform for a modern residential complex that unites residents, management companies, and technical staff in a single ecosystem. The main idea is to automate daily processes, improve service quality, and create a smart infrastructure.

Challenges Solved

Disjointed residents' services. We combined all scenarios in a single app.
Unstable legacy architecture. Introduced a step-by-step modernization plan without a system shutdown.
Increasing system load and scalability issues. Designed a microservices architecture.

A large number of roles and scenarios. We implemented a unified ecosystem for residents, management companies, and service providers
High security requirements. Implemented multi-layered protection for the platform and IoT devices
Need for real-time interaction. We implemented chats, application statuses, and live communication

Who we built it for

Complex residents

Users in need of a single digital hub for home services, requests, security, and smart-home features.

Management companies

Organizations that manage residential properties and need requests, communications, and operational processes automation.

Contractors and technical staff

Employees who process requests and maintain properties through a dedicated mobile app.

Key Modules & Features

Resident App

A central app for residents with access to all resident complex services:

Digital keys and guest QR codes.
Video intercom.

System Overview

The platform is designed as a scalable microservice ecosystem with real-time scenarios and IoT infrastructure support.

Backend architecture

The server part is built on NestJS with a module microservice architecture.

For scalability and fault tolerance, interaction is implemented through a message broker (RabbitMQ).

Data layer

A hybrid storage model is used:

PostgreSQL for transactional data.
Redis for caching, real-time data, and chats.

Frontend architecture

Residents’ apps are built on React Native with a single codebase for iOS and Android.

The admin panel is built using Next.js + AdminJS.

Infrastructure & scalability

The app infrastructure allows for step-by-step legacy parts modernization without the need for a system shutdown. New features are introduced as independent modules and microservices.

Technology Stack

Security approach

Platform security was built on the principles of proactive security and compliance with OWASP Top 10 recommendations.

Platform security

JWT authentication and RBAC.
SQL injection and XSS protection.
bcrypt password hashing.
CSP and CSRF/Clickjacking protection.
WAF and DDoS protection.

IoT security

TLS 1.2/1.3 encryption.
Unique TLS device certificates.
Secure onboarding via BLE/Soft AP.
Cryptographically signed OTA updates.

Services

Anna, UX/UI Designer

UX is built around the idea of “single ecosystem experience”. The user has to decide most of the routine tasks in one app.

Key principles:

minimization of the number of actions;
quick access to common functions;
transparency of application statuses;
unified visual style across web and mobile.

Particular attention was paid to the convenience of real-time scenarios: the management company communication, live updates, and IoT functions integrations.
