Security
Your mobile applications are safeguarded with advanced security methods.
Sensitive Data Encryption
We encrypt sensitive data in your mobile application with AES-256 so it cannot be read or used, even in the event of a breach.
Regular Security Tests
We analyse your application with regular security tests to identify and fix potential vulnerabilities at an early stage.
Advanced API Security
We continuously monitor and filter API and network traffic to protect against unauthorised access and malicious requests.
Two-Factor Authentication
By adding an extra layer of security to user accounts with two-factor authentication, we minimise the risk of unauthorised access.
Infrastructure
A robust infrastructure keeps your mobile applications always in service.
Reported Performance Metrics
We continuously monitor your mobile application services and deliver monthly availability and performance reports.
Auto-Scaling
Our infrastructure scales automatically to user load and resource usage, delivering high performance and an uninterrupted experience.
Global Distribution and Uptime Monitoring
We serve your application content quickly via global networks, continuously monitor availability and respond to any issues immediately.
High-Performance Servers
Thanks to our robust server infrastructure, we keep your mobile application running quickly, reliably and without interruption under all conditions.
Data Retention
We manage data for mobile applications in line with legal requirements and in a secure manner.
Regulatory Compliance
We build your mobile infrastructure in compliance with all applicable regulations, including KVKK and GDPR, so you can manage your data and processes securely.
Real-Time Backups
By continuously backing up your mobile application data, we provide a fast, seamless restore option in the event of data loss.
Recorded Operations
We record every user action in the mobile application, enabling you to build a transparent and auditable structure.
User Consent Management
We manage user permissions in accordance with legal requirements so you can protect data privacy and control consent processes.
How Do We Do It?
Thanks to the experience from more than 250 projects we've delivered, we know what it takes to run a flawless, optimised software development process.
Introduction and Initial Analysis
We clarify the goals, stakeholder expectations and scope, and evaluate the current situation, competitors, risks and objectives.
Solution Design and Project Planning
We define the technical requirements, content structure and project timeline, and build a roadmap for the design, development and testing processes.
Design and Experience
We design aesthetic, user-friendly interfaces aligned with your brand identity and work to deliver a flawless experience on every device.
Development and Integration
We build a scalable, secure and high-performance infrastructure with modern technologies and carry out the required system integrations.
