Message

At CapitalPlus Asset Management, I develop Laravel backend services and Nuxt/Vue interfaces for financial operations. My work includes a double-entry accounting engine, portfolio and NAV valuation workflows, and KYC and compliance controls.

At Flash Transfer, I built wallet and order-matching features for a crypto exchange, including real-time order book updates and integrations for market data and fraud detection. I also worked on hardening WebSockets, REST APIs, and microservice interactions.

Across roles at Madiavo CRM, Meta Lead Hunter, Five Marketplace, and JAAD Logistics, I developed REST APIs, relational database schemas, authentication, and application features for CRM, lead management, marketplace, and logistics platforms. My experience also includes production debugging, testing, performance optimization, and release support.
