At Nexar, I architect and maintain a real-time trading-signal engine that processes live market data, evaluates condition-tree strategies across 134 indicators, and publishes alerts through Redis Streams.

I previously delivered Lynkaz's multi-tenant procurement SaaS architecture, reducing inter-service coupling by roughly 40%, achieving a 99.9% uptime SLA, and scaling PostgreSQL beyond 100M rows while cutting query times by 55%.

I've also built sub-10ms Go APIs, GCP event-driven services, Stripe payment workflows, and low-latency PSX trading systems. I bring hands-on architectural ownership across Azure, AWS, GCP, Python, Go, security, and cloud-native distributed systems.
