// About Me

I engineer systems
built to last.

Senior Backend & AI Engineer with 5+ years building production-grade SaaS platforms, AI-powered applications, workflow automation systems, and scalable backend infrastructure.

I specialize in Node.js, Python, FastAPI, LangChain, RAG pipelines, and cloud-native AWS architectures. My work spans AI recruitment automation, workforce management, payroll platforms, AI meeting transcription, and multi-tenant SaaS products serving real business needs.

Experienced in AI automation workflows, real-time systems, microservices, cloud deployments, and production-grade backend architectures across recruitment, workforce management, payroll, and analytics domains.

I thrive with end-to-end ownership in remote-first, high-velocity environments — from architecture decisions all the way to production deployment.
