Building GEMA Plantation and GEMA Factory

FadhilMuhammad

Software engineer and IT consultant digitising palm oil operations, from field to office.

I work out how a business actually runs, design the system around it, and build it. Lately that means palm oil plantations and mills: field apps that work offline, dashboards for management, and the ERP integration in between.

About

Engineer by trade, analyst by habit.

Medan, Indonesia · UTC+7

I start with the problem, not the framework. I sit with the people doing the work, map how it really happens, then design and build the system behind it.

Field and mill apps for palm oil companies, a product site for a plantation ERP, self-ordering kiosks, and a Flutter cohort I helped teach.

Software Engineer, leading GEMA Plantation and GEMA Factory

B. Informatics Engineering, GPA 3.91

What I do

From the field visit to the training session.

Consulting, analysis, development and the material that explains it, by the same person. Fewer hand-offs means less gets lost.

IT consulting

You know something isn't working, but not what to build.

I go on site to estates, mills and outlets, talk to the people doing the work, and map the process as it really is. Then I write a plan you can act on: what to build, what to buy, and what can wait.

  • Field study
  • Process map
  • Scope & estimate
  • Build or buy
Example: GEMA Plantation

Systems analysis

The requirements live in people's heads and in spreadsheets.

Interviews turned into documents a team can build from: user flows, a data model and API contracts, agreed before anyone writes code.

  • User flows
  • ERD
  • API spec
  • Wireframes
Example: P3 System

Development

There's a plan. Now it has to ship and stay up.

Kotlin and Flutter on mobile, including offline-first apps and on-device AI. Next.js and .NET Core on the web, connected to the ERP behind them.

  • Android & Flutter
  • Web apps & CMS
  • APIs & ERP sync
  • CI/CD
Example: GEMA Factory

Team lead & training

The team needs to deliver, and the users need to adopt it.

I lead a small team (usually two developers, up to four) through reviews and pairing, train the people who'll use the system, and support clients online and on site.

  • Code review
  • User training
  • Client support
  • Docs in Notion
Example: BEKUP × Dicoding

Design & presentations

The system is good, but nobody outside the team understands it yet.

UI in Figma, plus the material that explains and sells it: product presentations, company profile decks and brochures for GEMA Plantation and GEMA Factory, made in Canva and Photoshop.

  • UI in Figma
  • Product decks
  • Company profile
  • Brochures
Example: SEMESTA AGRO

How I work

How I run a project

Six steps, each ending with something the client can look at, so decisions get made while they're still cheap.

  1. Discover

    Field visits, interviews with clients and field staff, and a look at the paper and spreadsheets in use.

    Field notes

  2. Analyse

    Map the current process and agree on what better looks like.

    User flows, rules

  3. Design

    Data model and wireframes. Cheap to change at this stage.

    ERD, wireframes

  4. Build

    Small increments the client can click through, shipped with CI/CD.

    Working software

  5. Ship

    Release, train the people who'll use it, and present it to management.

    Training, deck

  6. Support

    Stay close after launch, online and on site, and plan what comes next.

    Backlog

In practice

  • On site

    I visit estates and mills for field studies, and gather requirements directly with clients and the people who'll use the system.

  • Lightweight agile

    Short cycles with estimates up front, documentation in Notion and Discord for day-to-day talk. Scrum boards in ClickUp, Jira or Trello where the team uses them.

  • Small team

    I lead two to four developers on the GEMA products, with code review and pairing.

  • Present & train

    I present to clients and management, write the training, and support users after launch.

Working with AI

AI speeds up the work. The judgment stays mine.

I work alongside AI every day to think things through, learn faster and get first drafts done sooner. Understanding the business, deciding what to build and answering for the result stay with me.

Have a process that should be a system?
