Fransiscus Setiawan – AI Engineer and Solution Architect in Sydney

Who is Fransiscus Setiawan? Fransiscus Setiawan is an AI Engineer and Solution Architect based in Sydney, Australia. He builds AI agents, MCP servers, and enterprise AI systems using .NET, Azure, and production software architecture practices.

What does Fransiscus Setiawan build? He designs and implements systems that connect language models with real business workflows: retrieval pipelines, tool-calling agents, Azure AI integrations, event-driven services, and secure APIs.

AI Engineering Focus

My current work is centred on practical AI engineering rather than demos: MCP servers, agent orchestration, RAG systems, evaluation loops, local model experiments, and cloud deployments that can be operated by a real engineering team.

Enterprise AI on Azure and .NET

My background in .NET, Azure, and distributed systems helps me design AI products that respect integration boundaries, reliability requirements, data security, and deployment constraints. Typical building blocks include Azure OpenAI, Azure AI Search, Azure Functions, Durable Functions, Service Bus, ASP.NET Core, and SQL-backed services.

EV Charging and Smart Mobility

I have worked deeply in EV charging platforms, including OCPP-based systems, charging network integrations, and operational architecture. That domain experience informs AI work around diagnostics, anomaly detection, load-management assistance, and support workflows for charging infrastructure.

Technical Background

• AI: MCP, tool calling, RAG, Claude API, Azure OpenAI, Azure AI Search, local LLM experimentation, evaluation workflows
• Engineering: C#, .NET, Python, TypeScript, ASP.NET Core, REST, GraphQL, event-driven architecture
• Cloud: Azure Functions, Durable Functions, Service Bus, Key Vault, Azure DevOps, GitHub Actions, Docker
• Domains: EV charging, OCPP 1.6/2.0.1, enterprise integration, SaaS platforms, fintech, retail, energy

Professional Profile

I have worked as a Lead Engineer, Engineering Manager, Head of Engineering, and Solution Architect across enterprise software teams. This site is my technical archive: articles, architecture notes, experiments, and case studies from building production systems.
