Open to full-time roles

I build automation that keeps running after launch.

I am Khairul Muhtadin, an automation engineer working mostly in n8n with custom code where no-code runs out. I handle the whole delivery: mapping the real process, building the workflow, integrating the systems, then monitoring and maintaining it. n8n Ambassador for Indonesia and n8n Verified Creator.

Selected work

Each entry is a real build: what was broken, what I shipped, and what it runs on.

API Indonesia

Own product

Problem

Indonesian public data lives in government sites that go down, PDFs that change format, and spreadsheets that nobody maintains. Developers rebuild the same scrapers every time.

What I built

A REST API platform that serves 23+ data products behind one key, with a self-service dashboard, quota enforcement and subscription billing. Data refreshes on cron, so consumers never touch the source.

  • Cloudflare Workers
  • Hono
  • D1
  • KV rate limiting
  • Xendit billing
  • React dashboard

AI job publishing studio

Client build, 6 weeks

Problem

An animation studio published job content through five manual handoffs per post: scraping, cleanup, CMS formatting, taxonomy matching, then separate social drafting.

What I built

One publishing loop that accepts a URL, pasted text or a Telegram message, extracts the content with a primary and fallback path, then publishes to WordPress and distributes to five social channels. Stripe credit packs meter usage.

  • Next.js
  • Supabase
  • WordPress REST API
  • Firecrawl
  • Jina
  • Telegram Bot API
  • Stripe

Due diligence automation

Build sprint, 48 hours

Problem

Deal documents arrive as PDFs, DOCX and XLSX. Turning them into something an investment team can read took a person most of a day per deal.

What I built

An intake pipeline that parses all three formats, extracts and structures the facts that matter, then generates risk analysis and an investment thesis summary as a board-ready PDF.

  • Document parsing
  • Retrieval pipeline
  • Structured LLM output
  • PDF generation

Lead enrichment pipeline

Client work, LUR Growth

Problem

A US-market sales team qualified accounts by hand: pull a list, filter it against an ICP, copy records into the CRM, then start sequences one by one.

What I built

An automated chain that extracts and filters ICP accounts through the Dealfront API, pushes qualified records into Apollo, then triggers enrichment and email sequencing in GoHighLevel without a human step.

  • n8n
  • Dealfront API
  • Apollo
  • GoHighLevel
  • Webhooks

Multilingual content automation

Client work, OneKeyVisa

Problem

A visa consultancy rewrote and reformatted every article by hand for three language markets, which capped publishing volume.

What I built

One source article becomes publish-ready content in three languages, with the translation and editorial pass handled inside the workflow before it reaches the CMS.

  • n8n
  • LLM translation
  • Editorial passes
  • CMS publishing
