I lead two products at a major energy company in Dubai: a 3D geo-analytics platform for oil fields and a mobile analytics app for executives. My work turns production, economic, and asset data into interactive tools that reduce decision-making time from days to minutes.

For the geo-analytics platform, I built Three.js and React Three Fiber visualizations that stably render 2,000+ objects, alongside MapLibre maps, Kafka telemetry streaming, PostgreSQL, Redis, and JWT/OAuth 2.0 authentication. For the React Native analytics app, I delivered real-time access for 50+ executives, replacing Excel reporting with drill-down dashboards, custom visualizations, and automated production-potential recommendations.

Previously, I improved partner conversion by 25% and cut logistics order-processing time by 40% at FinTech Consulting Group. At Digital Ventures, I delivered IoT 3D monitoring for 10K+ devices, achieved 500 RPS real-time AI streaming at 40% lower CPU usage, and helped reduce deployment time from 25 to 5 minutes with Docker, Kubernetes, and CI/CD.

Across seven-plus years, I've built full-stack products with Node.js, NestJS, React, Next.js, TypeScript, PostgreSQL, Kafka, and WebSocket. I enjoy solving performance-heavy problems—from event-loop profiling and SQL optimization to 3D rendering, real-time systems, and LLM API integration.
