Case studies
Real projects, real outcomes
Not hypotheticals — named clients, the problem they came to us with, and what shipped.
Cross-platform commerce app for a growing retail chain
Problem
Needed a single mobile app for iOS and Android to replace an aging in-store-only ordering process, without doubling engineering cost.
Outcome
Shipped one React Native codebase covering catalog, cart, payments, and order management — live on both app stores in one release cycle.
Enterprise web platform built for high-volume transactions
Problem
Legacy platform couldn't handle peak transaction load and lacked real-time visibility for the ops team.
Outcome
Rebuilt the platform on Next.js and Node.js with a live analytics dashboard and API integrations — sustained high-volume traffic without degradation.
AI-powered analytics dashboard for predictive insight
Problem
Large datasets were being analyzed manually, with no forward-looking view for the team to plan against.
Outcome
Delivered a TensorFlow-backed predictive pipeline with interactive visualizations, cutting manual analysis time and surfacing trends before they hit.
