Software Engineering for Marketplace Platforms
Build scalable, trust-driven marketplace platforms, from two-sided B2C marketplaces and service aggregators to B2B procurement portals. We engineer the matching, payments, reviews, and logistics that power platform economics.
The Challenges We Solve
We have worked across dozens of marketplace & platform projects. These are the pain points we hear most, and know how to fix.
Chicken-and-egg supply/demand problem: platform must attract both sides simultaneously
Payment escrow, split payments, and multi-party settlements add regulatory complexity
Search relevance and matching algorithms directly impact GMV and user retention
Trust and safety (reviews, dispute resolution, fraud) must be built from day one
Scaling from 100 to 100K listings requires re-architecting search, feeds, and notifications
Our Marketplace & Platform Solutions
From product strategy to production deployment, our dedicated teams cover the full engineering lifecycle.
Two-Sided Marketplace Engineering
End-to-end platform architecture for buyer/seller marketplaces, user onboarding, listing management, search with faceted filters, booking/cart flows, and review systems. We have shipped marketplaces processing $10M+ GMV annually with 50K+ active users.
Payment Orchestration & Escrow
Stripe Connect, PayPal for Marketplaces, and custom escrow solutions. We handle split payments, platform commissions, refund workflows, payout schedules, and 1099/tax reporting. PCI DSS compliant payment flows from day one.
Search, Matching & Recommendation
Elasticsearch-powered product/service search with ML-driven relevance ranking, geo-proximity matching, price intelligence, and personalized recommendation feeds. We optimise for conversion rate, not just result count.
Trust, Safety & Dispute Resolution
Identity verification (KYC for high-value platforms), review moderation, automated fraud detection, dispute resolution workflows, and content policy enforcement. Built to scale from launch to millions of transactions.
PCI DSS, KYC & Consumer Protection
Marketplace compliance is jurisdiction-specific. We architect configurable compliance modules that adapt to local regulations as you expand into new markets: EU, US, APAC: without rebuilding core platform logic.
PCI DSS Level 1 for payment card processing and escrow accounts
KYC/AML compliance for high-value or financial marketplace transactions
GDPR / CCPA consumer data protection and consent management
Digital Services Act (DSA) transparency and content moderation obligations
Platform liability and consumer protection regulations per jurisdiction
