Hire the Best Database Freelancers
in Indonesia

I am a Researcher and Data Analyst with a background in Economics from Universitas Indonesia, experienced in transforming complex data and information into clear, actionable insights. I have worked on quantitative research, market and industry analysis, data cleaning, report writing, and presentation development through academic, international, and project-based experiences. Proficient in Excel, Stata, Google Sheets, PowerPoint, and Canva, I deliver structured, detail-oriented work that helps businesses, startups, and individuals make informed decisions. I prioritize clear communication, accuracy, and timely delivery, and I am committed to providing reliable, high-quality results tailored to each client's needs.

You're building a SaaS product, or adding AI to one that's already live. The backend needs to hold at scale. The codebase needs to stay clean. And AI features need to fit into the architecture properly, not bolted on as an afterthought. That's where I come in. I'm a full-stack developer specializing in SaaS development and AI integration. I build multi-tenant systems with Next.js, React, and Supabase on the product side, Laravel and Node.js on the backend, and connect LLMs (GPT/OpenAI, Claude/Anthropic, AWS Bedrock, Gemini) where they actually solve the problem. 🌟 What I Build: My foundation is SaaS infrastructure: multi-tenant architecture, REST APIs, authentication, billing, and AWS deployment, using TypeScript, PostgreSQL, Supabase, and MySQL as the core data layer. On top of that I build AI features, including RAG pipelines with vector search, document-aware chatbots, and LLM-powered workflows that fit cleanly into existing codebases without rewrites. – Multi-tenant SaaS development from MVP to production – AI integration into existing SaaS without breaking what works – RAG pipelines with vector search over your own documents and data – AI chatbots trained on your docs, websites, or internal knowledge base – Backend architecture with Laravel and Node.js: REST APIs, auth, billing, AWS deployment I'm not here to ship a flashy demo and disappear. And I don't train or fine-tune models from scratch, that's a different specialty. 🌟 Best Fit If: – You're building a SaaS MVP and need architecture that won't require a rewrite at scale – You have a SaaS in production and want to add AI features without touching what already works – You need RAG or a document-aware chatbot built properly, with real vector search rather than a wrapper around a prompt – A previous dev bolted AI onto fragile architecture and you need it fixed – You want a developer who tells you when AI isn't the right solution for the job 🌟 Recent Work: – Enterprise feedback automation for a government client, built on Laravel with AWS Bedrock handling the AI layer. Laravel as the backend of a production AI system, not just a CRUD app. – Multi-LLM chatbot SaaS with RAG pipelines, vector search, multilingual support, and EU data residency. Supports GPT, Claude, and Gemini. Stack: Nuxt + Node + AWS. – Multi-tenant lead-capture SaaS with an OpenAI-powered co-pilot. Stack: Next.js + Supabase + TypeScript. – B2B SaaS for automated PDF packet generation with a serverless merging engine. Stack: React + TypeScript + Cloudflare Workers. 🌟 Tech Stack Core: Next.js, React, Laravel, TypeScript, Node.js, Vue.js, Nuxt.js, Astro.js, Tailwind CSS AI and LLM: Claude (Anthropic), GPT (OpenAI), AWS Bedrock, Gemini, RAG, vector search Infrastructure: Supabase, PostgreSQL, MySQL, AWS, Docker I'm available immediately. Send me a brief about what you're building and I'll respond within 2 hours during business days with a clear yes/no on fit and a rough timeline if we proceed.
