The Backbone of Financial SaaS
FinTrack is more than just an API; it is a specialized ecosystem composed of independent, high-performance microservices. From AI-native advice through FinBot to secure peer-to-peer debt verification via the GBS System, FinTrack redefines financial reliability.
Official Product Demonstrations
Sovereign Financial Control
950+ Global Currencies
Real-time conversion with a specialized "significant change" algorithm only recorded at the 6th decimal threshold.
GBS Debt System
Encrypted video evidence and legal commitment tracking for secure peer-to-peer debt management.
FinBot AI Assistant
Powered by Mistral 7B via FastAPI worker, providing proactive budget optimization advice.
Reporting Engine
Multi-format generation (PDF, Word, Excel, XML, MD) for professional accounting integration.
The 6th Decimal Performance Logic
To maintain extreme database efficiency for historical exchange data, we implemented a multiplier-based threshold system. New records are only created if the rate fluctuation exceeds the 6th decimal place.
Impact: 40% Reduction in Storage Volume
var diff = Math.Abs(newRate - existingRate);
if (diff < 0.000001M) {
UpdateMultiplier(existingRecord);
} else {
InsertNewRateHistory(newRate);
}
Subscription Tiers (Freemium)
Integrated secure checkout via Stripe SDK.

Three Pillars of the System

A FastAPI service running Mistral 7B via Ollama. Specialized for heavy asynchronous processing.
WinTrackManager

Dual-Database Strategy
We separate live transaction data from audit logs to ensure zero performance degradation and total system auditability.
- MainDB (PostgreSQL): Current state records.
- LogDB (PostgreSQL): Audit trail for all POST/PUT/DELETE ops.
Containerized Observability
Prometheus
Real-time metric collection from API nodes and Docker containers via cAdvisor.
Grafana
High-fidelity dashboards for system health, CPU/RAM usage, and throughput monitoring.
Auto Backups
Dedicated backup container performing daily full snapshots of MainDB at 03:00 AM.
ngrok Tunnel
Production-proxy testing for localized microservices development.
The Authentication Lifecycle
Registration Hook
6-digit OTP verification via SMTP before identity creation.
Identity Persistent
ASP.NET Core Identity assignment with specific role claims (Plus/Pro).
JWT Issuance
Claims-based token generation for cross-microservice authorization.
