Full-Stack AI Developer | RAG, LLM & AI Automation | Laravel, Next.js

Job Success
Semarang, Indonesia - 11:00 am local time
Most developers treat AI as a plugin. I build it as part of the architecture, so the intelligence actually fits your data, your stack, and your users.
I'm a full-stack developer with a perfect 5.0 rating across every completed project, now focused on the area where I do my best work: connecting modern web applications to real AI capability. While a lot of AI developers live entirely in the Python world, I work where most businesses actually are (Laravel, Next.js, TypeScript, and PostgreSQL) and add the AI layer on top without forcing you to rebuild everything.
What I can build for you:
• RAG systems: let your users ask questions and get answers grounded in your own documents, with embeddings, vector search (pgvector), and streaming responses.
• LLM integration: Claude and OpenAI wired directly into your app for chat, content, search, and smart features that go beyond a simple API call.
• AI assistants & lead/support flows: conversational tools that capture leads, answer customers, and handle real intent, not just scripted FAQ replies.
• AI automation: n8n workflows that connect your AI to the tools you already use (calendars, CRMs, notifications) so the busywork runs itself.
My stack:
Backend: Laravel, REST APIs, Node.js ·
Frontend: Next.js, React, TypeScript, Tailwind CSS ·
AI: Claude API, OpenAI API, RAG/embeddings, pgvector ·
Automation: n8n ·
Databases: PostgreSQL, Supabase, MongoDB
How I work:
I keep things clear from day one: we agree on scope and milestones before I write a line of code, I send regular updates so you're never guessing, and I deliver tested work with documentation you can actually hand to the next person. You get a developer who communicates like a partner, not a contractor who disappears.
You can see real, working examples in my portfolio below: AI applications I've built across real estate, e-commerce, healthcare, and document Q&A, each one demonstrating a different piece of the AI + full-stack puzzle.
If you've got an idea for an AI-powered product, or an existing app that needs real AI capability added, send me a message and tell me what you're building. I'll tell you honestly how I'd approach it.
