What I'm looking for

I'm looking for backend/cloud roles where I can design scalable APIs, automate DevOps workflows, improve reliability, and grow within a collaborative, product-focused engineering team.

I am a backend engineer with hands-on experience building scalable APIs and event-driven systems using Go, Python, and JavaScript. I focus on reliable, maintainable backends that support growth and real-time use cases.

I designed and developed a modular ERP backend and multi-tenant architecture, built production React Native apps, and integrated authentication, payments, and real-time notifications. I have delivered end-to-end features from schema design to client-facing mobile integrations.

On the infrastructure side, I deploy and automate cloud-native systems with AWS, Docker, Kubernetes, and Terraform, and implement CI/CD pipelines to speed deployments. I’ve reduced costs through containerization, automated deployments, and instance optimization while improving monitoring, logging, and security.

I contribute to open-source projects and build developer tooling, and I seek opportunities where I can drive backend reliability, observability, and scalable architecture in collaborative teams.
