Results & Impact
Lexa Technologies is a robust, end-to-end algorithmic trading solution that combines real-time systems, financial integrations, and scalable architecture. It demonstrates strong expertise in full-stack development, event-driven systems, and fintech infrastructure. The platform successfully eliminates manual trading by connecting TradingView signals directly to IBKR execution. With a multi-tenant architecture, it supports numerous clients with isolated data and shared infrastructure. Built-in safeguards like the kill switch and position controls provide circuit-breaker functionality during market volatility. Real-time P&L dashboards and audit logs build client trust, while a centralized admin panel manages client onboarding, VPS allocation, and trade monitoring. Technical achievements include sub-second execution using Socket.io architecture, independent admin and client backends with synchronized data, fault tolerance through retry mechanisms and VPS health monitoring, security best practices with JWT authentication and bcrypt hashing, and flexible deployment supporting local, VPS, and cloud-based environments.
