Products built for real-world scale.
From fintech to healthcare, we've engineered platforms that serve millions of users and process billions of events. Here are some of the products we're proud of.
Multi-Currency Payment Platform
Challenge
A rapidly growing fintech needed to process multi-currency payments across 30+ countries with real-time settlement, fraud detection, and full PCI-DSS compliance — all within a 6-month launch window.
Solution
We designed a microservices architecture with event-driven payment orchestration, multi-provider failover (Stripe, Adyen, local gateways), real-time fraud scoring, and a merchant dashboard for transaction management.
“WOWO didn't just build our payment system — they architected our entire financial backbone. The platform has processed over $500M without a single critical incident.”
Enterprise Analytics Dashboard
Challenge
An enterprise SaaS company needed a white-label analytics platform that could ingest 1B+ events daily, provide real-time dashboards, custom reporting, and role-based access for 200+ enterprise clients.
Solution
We engineered a multi-tenant analytics platform using ClickHouse for time-series data, custom D3.js visualizations, a report builder with drag-and-drop, and a white-label system that lets clients embed analytics in their own products.
“The analytics platform became our most-requested feature and directly drove a 40% increase in enterprise plan upgrades.”
Multi-Chain DeFi Wallet
Challenge
Build a non-custodial wallet supporting Ethereum, Solana, and Polygon with token swaps, staking, NFT management, and a seamless onboarding experience for non-crypto-native users.
Solution
We developed a multi-chain wallet with abstracted blockchain interactions, a custom swap aggregator for optimal routing, staking interfaces for major protocols, and an NFT gallery with IPFS-backed metadata.
“WOWO's deep Web3 expertise was critical. They delivered a wallet that's both technically robust and genuinely easy to use.”
Two-Sided E-Commerce Marketplace
Challenge
Launch a two-sided marketplace with 10K+ sellers, real-time inventory sync, dynamic pricing algorithms, multi-carrier logistics integration, and a seller analytics dashboard — in under 5 months.
Solution
We built a Next.js storefront backed by a Go-based microservices engine, Elasticsearch for product discovery, Stripe Connect for seller payouts, and custom logistics APIs connecting UPS, FedEx, and DHL.
“We went from concept to 10K sellers in 5 months. The platform handles Black Friday traffic without breaking a sweat.”
HIPAA-Compliant Patient Platform
Challenge
A multi-clinic healthcare network needed a unified patient management system with scheduling, telemedicine, e-prescribing, and secure data exchange — all fully HIPAA-compliant with HL7 FHIR interoperability.
Solution
We built a React-based patient portal with Python backend, integrated with major EHR systems via FHIR APIs, added telemedicine with WebRTC, and implemented end-to-end encryption for all patient data.
“Our clinicians save 60% of admin time. Patients love the portal. WOWO handled the HIPAA complexity flawlessly.”
Real-Time Social Engagement Platform
Challenge
Build a social platform from scratch that could handle 500K+ concurrent users with real-time messaging, live content feeds, push notifications, and AI-powered content moderation — all on iOS and Android.
Solution
We built a cross-platform app with React Native, backed by a WebSocket-based real-time engine, Redis pub/sub for message distribution, and a custom ML pipeline for content moderation that processes 10K+ posts per minute.
