Eugene Haustov

I design and deploy robust back-end infrastructure engineered to protect and scale business revenue. Instead of managing development hours, I deliver fully autonomous, production-ready solutions that eliminate financial leakage, prevent subscriber churn, and automate real-time business visibility.

My expertise lies in architecting complex data models, deep behavioral telemetry, and resilient transactional workflows for high-ticket digital and hybrid subscription systems.

Core Solutions I Deliver:

Predictive Retention Infrastructure: Custom telemetry systems utilizing Subscription & Network Health frameworks. The system models customer engagement in real-time, detecting drops in activity before cancellation occurs to trigger proactive retention.

Advanced Fintech Engineering: Complex, bulletproof Stripe architectures handling custom billing models, multi-tier subscriptions, automated refunds, and complex subscription-pause logic with zero database desynchronization.

Business Anomaly Detection: Specialized event-logging and automated filtering systems that identify operational anomalies and data inconsistencies before they impact the bottom line.

Real-Time Financial Control: Highly structured P&L dashboards and custom admin panels integrated directly into the core database for accurate, instant financial decision-making.

The Engineering Stack:

I build high-velocity, low-maintenance serverless systems using Node.js, Next.js, PostgreSQL, and Stripe API.

I do not bill for time spent in front of a screen. I deliver fully operational, high-performance business infrastructure that actively secures and scales your financial metrics.
