I've built and led development of high-load CRM and ERP platforms serving 100k+ concurrent users at Nevasoft. Leading a six-engineer team, I owned Laravel backend and React frontend architecture from scratch.

I cut page load time from 60 seconds to under one second, reduced database load by 65%, and increased overall throughput by more than 200%. I've also integrated banking APIs, payment gateways, telephony, and other third-party services through reusable abstraction layers.

Across Nevasoft, Duke Technology, Maint, and an NDA CRM platform, I've delivered real-time analytics, WebSocket chat, payment integrations, internal tools, and performance-focused full-stack features using PHP, Python, React, databases, caching, and microservices.
