Case Studies

Enterprise Delivery

High-impact projects across logistics, library systems, and secure real-time communications.

ETA Accuracy

Challenge

A national courier needed unified driver and customer apps with offline-first delivery tracking, push notifications, and sub-second location updates across 2,000+ active drivers.

Solution

Architected a React Native (Expo) monorepo with shared business logic, WebSocket-backed live tracking, background geolocation, and a NestJS event-sourced backend on AWS Lambda with SQS fan-out for order state machines.

Impact

  • Reduced delivery ETA errors by 34%
  • 99.7% crash-free sessions across iOS & Android
  • Onboarded 2,000+ drivers in 6 weeks

A11y Score

Challenge

A university library consortium required modern React UI widgets embedded inside a legacy Angular 12 ILMS without a full rewrite — preserving Angular routing, auth, and change detection.

Solution

Built a Web Components layer with Shadow DOM isolation, custom event buses for Angular↔React communication, and a shared design token system. Delivered catalog search, reservation flows, and accessibility-compliant forms as framework-agnostic custom elements.

Impact

  • Shipped 12 React widgets into production Angular shell
  • Zero regression in Angular change detection cycles
  • WCAG 2.1 AA compliance across all new components

Secure Communications

Encryption
1st Try
Audit Pass

Challenge

A healthcare SaaS client needed HIPAA-aligned real-time data sync between clinicians with no server-side decryption of payload content — only metadata routing.

Solution

Designed a signaling server on NestJS with TURN/STUN on AWS, implemented DTLS-SRTP data channels with client-side AES-256 encryption, and built a React dashboard for session audit trails without exposing plaintext.

Impact

  • Zero plaintext data at rest on servers
  • Sub-200ms P2P sync latency in EU regions
  • Passed third-party security audit on first review
