What I Do

Focus & Approach

I build reliable, automation-heavy systems with a focus on clarity, maintainability, and dependable delivery.

As an AI workflow automation engineer, I build production-grade backend systems that integrate large language models (LLMs), vector databases, and scalable APIs to automate real-world operations.

  • Design backend systems and workflow orchestration for AI-powered products
  • Build production APIs with FastAPI and Django for business-critical services
  • Integrate LLM services, vector search, and task queues into reliable systems
  • Turn messy manual operations into measurable, automated workflows

Products & Experiments

Selected Projects

Guest Automation System

Manual guest check-in, FAQs, and service requests created response delays and heavy operational overhead.

An AI-powered workflow automation system that integrates WhatsApp APIs, LLM-based response generation, and backend automation pipelines to reduce manual guest operations.

Internal Workflow Tools

Operations teams depended on repetitive reporting and manual notification processes.

A backend workflow automation suite with scheduled tasks, API integrations, and AI-assisted routing that streamlines internal reports, alerts, and administrative operations.
