Hi, I'm Tim 👋

Software Engineer · AI Engineering · Data Systems · Backend Infrastructure

I build AI-powered applications, data-intensive systems, and scalable backend infrastructure.

👨‍💻 About Me

I'm a Software Engineer interested in building systems at the intersection of AI, data, and backend infrastructure.

My work focuses on:

  • AI Engineering — LLM applications, RAG, AI agents, and model-powered products
  • Data Systems — ETL pipelines, analytics platforms, data processing, and MLOps
  • Backend & Infrastructure — APIs, databases, containers, observability, and cloud-native systems

I enjoy taking a problem from data ingestion → backend services → AI workflows → observability → user-facing products and turning it into a complete, maintainable system.


🚀 What I Build

🤖 AI Engineering

Building practical AI systems rather than isolated model demos.

  • LLM applications and AI-powered products
  • RAG pipelines and vector search
  • AI agents and tool-based workflows
  • LLM inference, evaluation, and observability

📊 Data & ML Systems

Designing pipelines that transform raw data into useful products and insights.

  • Data ingestion and ETL
  • Analytics pipelines
  • MLOps and model workflows
  • Data platforms and automation

⚙️ Backend & Infrastructure

Building the foundation that makes applications reliable and operational.

  • Backend APIs and service architecture
  • PostgreSQL and data storage
  • Docker and containerized applications
  • Monitoring and observability
  • Cloud and automation
