From mobile apps to AI fraud defense & Web3 settlement.
Zero downtime sustained across 18M+ mobile & web transactions on Black Friday.
p95 checkout endpoint latency, reduced from 940ms through edge caching & async queueing.
Fraud loss rate achieved by custom PyTorch inference model vs 1.8% industry baseline.
The Challenge
OmniPay was operating with fragmented engineering silos: disparate native iOS and Android codebases that lagged each other by months, a legacy web portal suffering high user drop-off, and fragile backend scripts that crashed under traffic spikes.
Compounding the challenge, rising fraud attacks were draining merchant trust, and impending enterprise contracts required stringent SOC2 compliance and automated Web3 escrow settlement for international accounts. They needed an all-in-one engineering partner capable of unifying mobile, web, cloud, AI, and security without pausing live transactions.
What We Built
i3Codex deployed an integrated squad spanning mobile developers, cloud architects, AI researchers, and security auditors. We delivered five synchronized systems over a 16-week sprint:
Cross-Platform Mobile App (iOS & Android)
Engineered with Flutter and native Swift bridges, featuring 60fps biometric checkout, local offline SQLite reconciliation, and automated TestFlight / Google Play deployment pipelines.
High-Performance Next.js Web Portal
Built an ultra-fast merchant dashboard with server-side rendering, sub-second TTFB, and tokenized design systems achieving a 99/100 Lighthouse performance score.
DevOps, Kubernetes & Multi-Region Cloud
Architected Terraform-managed multi-region AWS EKS clusters with ArgoCD GitOps, automated canary deployments, and Prometheus/Grafana monitoring sustaining 99.99% availability.
AI-Powered Real-Time Fraud Detection Engine
Trained and deployed a low-latency neural model that evaluates 120+ transaction signals in under 18ms, preventing unauthorized transactions while maintaining zero false declines for verified users.
Web3 Smart Contract Escrow & DevSecOps Audit
Authored gas-optimized Solidity smart contracts for decentralized cross-border settlements with multi-sig governance, while hardening the infrastructure to pass SOC2 Type II audit.
“i3Codex delivered our entire mobile application, web dashboard, and AI fraud engine in 16 weeks without a single missed milestone. Their full-stack breadth across mobile, cloud, AI, and cybersecurity is unmatched.”
Autonomous AI Document Extraction
How our applied AI squad engineered automated multi-modal parsing across 250k legal contracts with 99.4% citation accuracy.
