Fintech Ledger & Settlement API
An immutable double-entry ledger platform with algorithmic AML sanction screening and real-time bank reconciliation processing $15M+ daily.
Engineering a Scalable Multi-Vendor Marketplace Ecosystem
When Cross-Border Payments Corp partnered with HIFISYS, their core goal was to eliminate digital barriers for emerging Direct-to-Consumer brands and creators. Monolithic legacy systems were causing cart abandonment, inventory discrepancies, and severe latency during product drop campaigns.
HIFISYS engineered an enterprise marketplace solution combining a lightning-fast customer storefront with distributed vendor control portals, automated payout settlement infrastructure, and sub-second catalog search across thousands of product variations.
Core Objectives
- Create a mathematically proven double-entry ledger with zero rounding drift; automate real-time OFAC/AML sanctions screening in under 150ms; and achieve automated bank wire settlement verification.
Sub-Second Catalog Search
Elasticsearch & Redis caching tier delivering instantaneous filtering across 50,000+ SKUs.
Automated Split Settlements
Integrated Razorpay Route to disburse vendor earnings and deduct platform commissions in real time.
Autonomous Logistics Pipeline
Webhook-synchronized courier dispatch, automated AWB generation, and multi-courier tracking.
Challenges Faced & Architectural Solutions
How our engineering squads transformed business bottlenecks into scalable technical advantages.
Legacy Contention & Severe Mobile Drop-off
Processing high-frequency cross-border remittances across 14 currencies resulted in periodic end-of-day reconciliation discrepancies and manual AML verification delays that took hours per compliance ticket.
- 68% mobile cart abandonment due to complex multi-page checkout.
- Manual commission payouts causing 7+ day settlement delays for sellers.
- Database thread exhaustion during simultaneous multi-vendor product launches.
Decoupled Multi-Tenant Cloud Architecture
Engineered a distributed Laravel & Kafka event streaming backbone with horizontal worker autoscaling, automated FX rate locking via WebSocket feeds, and an encrypted compliance auditor portal.
- 2-step frictionless checkout with native digital wallets & OTP auto-fill.
- Real-time automated split payments directly to vendor bank accounts.
- Redis key-value caching layer absorbing 95% of read queries.
