🚀 Building reliable systems, distributed architectures, and AI-powered developer tooling.

Portfolio • GitHub • LinkedIn • Email

I'm a Software Engineer with 3+ years of experience building scalable backend systems, fintech infrastructure, cloud-native platforms, and AI-powered automation tools.

My work ranges from settlement engines processing millions of transactions to observability platforms, event-driven architectures, and autonomous incident investigation systems.

I enjoy owning systems end-to-end—from architecture and development to deployment, monitoring, debugging, and production reliability.
