What I'm looking for

I’m looking to build scalable, event-driven backend systems—especially payments and data workflows—where I can ship production APIs, improve performance, and grow into cloud-native (AWS/GCP) architecture using CQRS, event sourcing, and distributed tracing.

I’m a Backend Engineer with 3 years of hands-on experience building production-ready systems. I specialize in Node.js microservices, relational and NoSQL databases, and payment integrations with Stripe and Square, delivering solutions across 5+ projects in fintech, logistics, and SaaS—from architecture to deployment.

I architect RESTful APIs with full documentation and versioning, and I build secure payment flows (subscriptions, refunds, and webhook reconciliation) for production-scale reliability. I’ve improved backend throughput by over 30%, use RabbitMQ-based event-driven architecture to reduce coupling and enable async processing, and strengthen performance through database optimization (indexing, caching with Redis). Currently, I’m exploring Py Python for data pipelines and automation scripts, plus cloud-native deployment patterns on AWS & GCP, including CQRS, event sourcing, and distributed tracing.
