What I'm looking for

I seek senior backend or technical lead roles where I can architect scalable microservices, improve observability and performance, mentor teams, and drive reliable IoT or e‑commerce platforms.

I am a Senior Backend and Full-Stack Developer with 15+ years' experience and 7+ years focused on Node.js, Express, NestJS and MongoDB, delivering production-grade enterprise systems, IoT automation platforms and high-throughput microservices. I architected real-time IoT alert and emergency response systems for Ezlo Protect, built telemetry APIs using MQTT and Kafka, and led teams of 6–10 developers for US-based enterprise clients.

I drive performance and reliability through profiling, memory-leak resolution, Kubernetes autoscaling, and observability with OpenTelemetry, Prometheus and Grafana, while maintaining 80%+ automated test coverage with Jest and CI/CD pipelines. I have delivered AI-driven e-commerce features for MySureFit.co, migrated PHP monoliths to Node.js microservices, and implemented secure high-traffic APIs with JWT/OAuth2 and multiple payment gateways.
