Data & automation engineer

Christian
Anejo

I build the pipelines, workflows, and collection tools that turn messy operational data into decisions people can act on. Most of it runs quietly in production, from agency client systems to programmes serving smallholder farmers.

Selected work

Things I've built that people and businesses now depend on, doing real work that nobody has to think about.

Data, agricultural NGO

Agricultural field-data system

The collection system field teams use to record what happens at every district, pod and site, 9 districts and 46 pods in all, so records come back clean instead of needing a week of tidying.

  • ODK / Kobo
  • XLSForms
  • Supabase

Data, agricultural NGO

Rural retail sales analytics

Pipelines and dashboards behind field officers and farmer prospecting: how each district and shop is really selling, and early warning when a dealer starts slipping away.

  • SQL
  • Dashboards
  • Excel

Data, agricultural NGO

Stakeholder alerts & reporting

Automatic alerts and reporting emails that keep decision-makers current on operations, so nobody spends their morning pulling numbers by hand.

  • n8n
  • Apps Script
  • Reporting

Automation, agricultural NGO

Contract renewals that don't get missed

Reads the HR paperwork, works out whose contract is about to lapse, and tells their manager before it does. Days of chasing paper between desks, now minutes, and nobody finds out too late.

  • Apps Script
  • Document parsing
  • Automated alerts

Automation, property management client

Field service planning that plans the route, not just the job

Repair jobs arrive by email, emergency form and partner company. This reads them all, books the right engineer on the right day, and turns the day into a sensible driving route. Emergencies jump the queue, the rest re-plans itself. Eight minutes a booking down to thirty seconds, across 503 slots with no clashes.

  • n8n
  • Route optimisation
  • Vision AI
  • Scheduling

Automation, vending operator

Customer support that always answers

Vending machines in amusement parks across two countries. When one eats a family's money, they message the number on the front. This reads the message and the photo, works out what failed, answers in their language, and issues a refund code if one is owed. 800+ cases, usually inside a minute, seven languages.

  • n8n
  • WhatsApp
  • Postgres
  • Vision AI

Automation, e-learning software client

Bilingual content generator

One brief in; a finished, illustrated article out in English and Dutch. It researches against live search and the client's own product docs, so the copy matches what the software actually does. It files to the CMS as a draft, and a person still presses publish. 44 articles so far.

  • n8n
  • Search APIs
  • LLM APIs
  • CMS APIs

Automation, healthcare procurement client

A content generator that knows when not to post

Its audience is medical specialists, where generic posting does real damage. So it watches 22 healthcare sources and puts every story through five rounds of filtering before a word gets written. What survives becomes a Dutch LinkedIn post with a branded image, waiting in the comms inbox for a yes. Nothing publishes itself.

  • n8n
  • RSS & scrapers
  • LLM APIs
  • Branded visuals

Automation

Automated hiring, up to the final interview

Hiring that goes further than screening CVs. It reads every application, then phones candidates and runs the first two rounds itself, holding a real conversation. Everyone is compared on the same basis, and only the shortlist worth a human's time comes through. The only interview a person runs is the last one.

  • Voice AI
  • OpenAI

Automation

Finding and reaching the right people

Works out who actually makes the decision at a target company, finds a verified way to reach them, writes an opener specific to them rather than a mail-merge, and keeps the follow-up organised.

  • Airtable

Automation

Proposals out the same hour as the call

Turns the notes from a sales call into a finished, properly written client proposal, sends it internally for a yes, then delivers it while the conversation is still fresh instead of three days later.

  • n8n
  • Airtable
  • OpenAI
  • Gmail

Automation

Invoices that file themselves

Spots invoices as they arrive in the inbox, reads the amounts, dates and supplier off them, and puts everything into one place, so nobody is retyping numbers off a PDF.

  • PDF.co
  • OpenAI

I used to spend hours writing blog posts, but now I just fill out a simple form with my ideas, and it becomes a beautifully written blog post that goes straight to my site in two different languages in less than five minutes. Thank you!

Background

I'm a mechatronics engineer turned data and automation engineer. I build the unglamorous machinery that lets an organisation act on its own data: pipelines, workflows, dashboards, and the collection tools that hold everything together.

Most of my work sits where software meets the real world. I've built automation that businesses run on daily, and I've spent long days at distribution sites making sure the records that leave a laptop reach the farmer at the front of the queue. The rule is the same in both places: build it so it holds when someone depends on it.

Have a process that should run itself? Let's build it.

Whether it's an automation that removes a daily bottleneck or a data system that makes the field legible, send a note and I'll reply.
