Case Studies

Real work, delivered in production.

These are projects PMCODE has designed, built, and delivered for real clients. Each one started with a business problem and ended with a working solution in production.

Case Study 01

Ride-hailing platform development

Client context

A mobility company needed to launch a ride-hailing service with a passenger app, driver app, and a backend system to manage bookings, trips, and payments.


Business need

The client required a complete, production-ready platform that could handle real-time ride matching, trip tracking, and payment processing from day one.


What PMCODE delivered

  • Passenger mobile application (iOS and Android)
  • Driver mobile application with real-time navigation
  • Backend API for ride matching, trips, and payments
  • Admin dashboard for operations management
  • Deployment and production setup

Technical highlights

  • Real-time location tracking and ride matching
  • Cross-platform mobile apps with native performance
  • Scalable backend architecture
  • Payment gateway integration
  • Automated notifications for drivers and passengers

Result

The platform was delivered and launched in production. The client was able to operate their ride-hailing service with a working mobile experience for both passengers and drivers.


Technologies used

Case Study 02

AI audio processing in production

Client context

A company needed to process large volumes of audio recordings as part of their business workflow, requiring transcription, analysis, and structured output extraction.


Business need

The team was spending significant time manually reviewing audio files. They needed an automated solution that could extract relevant information and reduce processing time.


What PMCODE delivered

  • Automated audio transcription pipeline
  • AI-powered information extraction from transcripts
  • Structured output with key data points
  • Integration with the client's existing workflow
  • Production deployment with monitoring

Technical highlights

  • Speech recognition with high accuracy on domain-specific audio
  • Large language model integration for structured extraction
  • Batch and real-time processing modes
  • API integration with client's internal tools

Result

The system was integrated into the client's production environment. Manual audio review time was significantly reduced, and the team could focus on higher-value tasks instead of transcription work.

Case Study 03

Social and engagement features for a mobile platform

Client context

An existing mobile application needed to add social and community features to increase user engagement and retention on the platform.


Business need

The client wanted users to interact with each other within the app - sharing content, following profiles, reacting to posts, and receiving personalized notifications.


What PMCODE delivered

  • User profile and follow system
