Client

We worked with a tech startup aiming to simplify the generation of barcodes and QR codes for various uses — marketing, contact info, product labels — making sure the service is fast, reliable, and easy for both technical and non-technical users.

  • Tech startup focused on barcode/QR services
  • Targeting marketers, small businesses, event organizers, and developers
  • Wanting both static & dynamic code options

Timeline

The project was completed over 4 months. It included phases for planning, design, API integration, testing, and launching. Continuous iteration was done based on user feedback through beta testing.

  • Requirement gathering & wireframing
  • Backend & API integration for code generation
  • Frontend UI/UX design and beta testing

Goals

The aim was to deliver an intuitive, feature-rich tool that could generate barcodes and QR codes quickly, allow customization, support dynamic links, and scale with real user demand, while maintaining high quality in both static and dynamic modes.

  • Fast static & dynamic code generation
  • Customization: colors, logos, frames
  • Scalable backend and reliability

Services

We built modular services: a robust backend for generating codes, APIs for integrations, UI components for customizing appearance, and performance optimizations so codes generate quickly even under high load.

  • Static & dynamic code libraries (QR + barcode)
  • API endpoints for integrations (e.g. e-commerce, printing services)
  • Design customizations (color, logo, shape, frames)

Challenges

The project faced a number of challenges involving performance, compatibility, and user localizations. Ensuring the codes are scannable under various conditions, supporting custom designs without compromising readability, and handling large volumes of generation requests were among the key difficulties.

  • 🔴 Ensuring scannability for codes with logos & custom colors
  • 🔴 Managing server load and response time under spikes of use
  • 🔴 Supporting multiple code standards (barcode formats, QR types)

Dynamic vs Static Codes

Introduced static codes for simple, permanent use, and dynamic codes which allow the destination to be changed over time without regenerating the code.

Customization Features

  • Allow users to upload logos and adjust placement
  • Color picker for foreground & background elements
  • Option for frames or label text around codes

Performance & Scaling

  • Cache generated codes where possible
  • Use efficient libraries for code generation
  • Optimize image formats & sizes for web & print

API Integration & User Feedback

Built clear API docs, user dashboard, and gathering feedback through beta users to ensure ease of use and feature alignment.
