The Challenge & Their Solution
Challenges
Solution
Web View Issue on iPhone Devices
There was an incompatibility with the iPhone's web view rendering, causing unexpected behavior in the user interface.
iPhone Web View Fix
Fixed view handling issues on certain iOS versions by updating front-end code for WebKit compatibility and responsive design, ensuring support across all iPhone models.
Email Sending Issue via Server SMTP
We encountered problems sending emails through our server's SMTP configuration, resulting in failed or delayed message delivery.
SMTP Email Issue Resolution
After reviewing the SMTP logs and server configurations, we updated the authentication method and adjusted the port and encryption settings.
Duplicate Validations Across Multiple Stages
The system checks whether a serial number, tag, or eTag is valid at multiple stages. This creates extra work and delays in processing.
Store and Reuse Verification Results
Once a check is completed, the result should be stored temporarily and reused in the next steps, avoiding the need to perform the same check again.
Data Loss During Navigation or Refresh
When moving between screens or steps (especially on slower devices), some information might be lost, which forces re-entry of the same data or restarts the process.
Persist Key Information Temporarily
Keep key information temporarily saved throughout the full process, so it remains available even if there’s a delay, screen refresh, or minor connection issue.
Key Features
Secure Email Verification
The system verifies user identity through email-based OTP (One-Time Password) validation.
Real-Time Device Information
Displays detailed information about the device after successful verification.
Actionable Device Requests
Enables post-registration actions like service, supply, relocation, or updates.
Dynamic eTag Management
Users can generate and print tags if not already assigned to a device.

CodeChain helped us transform our MVP into a production-ready SaaS platform. Their engineers brought structure, clean code, and speed to the table.

Great team, great results.

CodeChain built us a custom applicant tracking system that fit our hiring process perfectly. The dashboard is intuitive, the filters are smart, and we’ve cut our screening time in half. Their team was quick to understand our needs and delivered without a single delay. It’s rare to find a dev partner who gets both UX and business logic.

Our online store couldn’t keep up with growing demand. CodeChain built a custom e-commerce backend that’s fast, scalable, and easy for our team to manage. They also integrated it with inventory systems and payment gateways flawlessly. Sales are up, downtime is gone, and our customer experience is better than ever. Professional, precise, and reliable.
Karan Bengani
Owner Kracknow
We needed to eliminate manual workflows across several departments. CodeChain designed a suite of internal tools that automated reporting, approvals, and document management. The time saved has been enormous — our teams are now focused on strategy instead of repetitive tasks. They’re technical experts who genuinely care about business outcomes.

Owner ZLine Laser technology
CodeChain built a custom mobile app for our large-scale conference, including ticketing, live updates, and networking features. Attendee feedback was overwhelmingly positive, and we were able to manage everything from a single admin dashboard. They delivered exactly what we needed, on time and within budget. Looking forward to working with them again.
