We do not build flimsy proof-of-concepts. We architect and code mission-critical software systems that process millions in transactions, withstand network outages, and scale smoothly.
High-Throughput VTU Telecom & Automated Bill Payment Switch
The Challenge & Problem:
The client was losing significant revenue due to single-provider API downtimes, manual airtime fulfillment delays, and ledger balance discrepancies where users were debited without airtime delivered.
The Estyne Solution & Architecture:
Estyne architected an automated multi-provider routing switch with sub-second failover across four telecom aggregators, built an immutable double-entry wallet ledger, and integrated automated virtual bank account funding.

Oppos: On-Demand Dispatch & Logistics Mobile Ecosystem
The Challenge & Problem:
The client required dual-sided iOS & Android mobile applications (one for customers booking parcels, one for dispatch riders) with real-time GPS tracking that would not drain driver battery or lose connection in low-network zones.
The Estyne Solution & Architecture:
Estyne engineered fluid cross-platform mobile apps with Flutter and React Native, implementing WebSockets for sub-second live rider tracking, offline trip caching with SQLite, and automated fare calculation.

Cre8Afrika: Creative Talent Academy & Video Streaming LMS
The Challenge & Problem:
Creating an educational marketplace that could stream high-definition course videos smoothly across Africa, process multi-currency payments (NGN, USD, GBP), and automatically issue tamper-proof digital certificates upon completion.
The Estyne Solution & Architecture:
Architected a Next.js App Router web application with CloudFront HLS adaptive bitrate video streaming, role-based dashboards for students and instructors, and automated PDF certificate generation with verification QR codes.

Enterprise Retail POS & Offline Hardware Integration
The Challenge & Problem:
Retail stores required cashier software capable of running seamlessly during total internet blackouts, communicating directly with ESC/POS thermal printers and barcode scanners, and synchronizing transactions to the cloud once connected.
The Estyne Solution & Architecture:
Developed a cross-platform desktop application with local encrypted SQLite database storage, USB/Bluetooth peripheral drivers, and a background synchronization worker that queues and pushes offline sales securely.
