Maintenance vs Operate: why "fix it when it breaks" is not enough for critical systems
What a retainer for a critical system should include: an SLA, change windows, backup verification, and reports leadership actually reads.
Technology Partner
We diagnose costly system problems, deliver solutions people use every day, and stay accountable after go-live.

Diagnose Paid discovery
Findings, priorities, and options before a large budget is committed.
Deliver Measured milestones
Changes shipped against written acceptance criteria, with a runbook.
Operate Monthly retainer
SLAs, monitoring, and controlled change after go-live.
Many vendors are done on go-live day. The operational problems start afterwards: changes pile up, knowledge walks out the door, and the system gets more fragile.
That is why we work in three clear phases. Diagnosis is based on evidence, delivery has acceptance criteria, and operations have an owner.

If one of these sounds familiar, the first step is a diagnosis and a clear model of responsibility, before anyone adds features.
A critical system depends on one vendor, or one person who is hard to reach.
Go-live is done, yet small changes take weeks and cost more than expected.
Integrations fail silently. The team finds out when a report comes back wrong.
Documentation is thin, so every audit or handover turns into an excavation.
Maintenance is purely reactive, with no SLA, no change window, and no reporting.
Build, buy, or fix decisions get made without leadership sharing the same view of the risk.
Request a Diagnose outlineHow we work
Each phase ends with an output you can judge for yourself before deciding on the next step.

We start from the business problem and the operational risk, not from a feature list. You can accept or reject the outcome without being locked in.

Once the scope is clear, we deliver changes against agreed acceptance criteria, with enough documentation to run them.

A system people use every day needs an owner. With Operate, MarkasDev stays accountable after go-live.
We use these capabilities inside Diagnose, Deliver, and Operate, depending on your problem. We only offer what we can deliver today.
Web applications and custom software for processes that off-the-shelf tools do not cover.
AI applied to the processes you already run, to cut manual work, with human oversight and careful data handling.
Apps that support field operations or services, when scope and ownership are clear.
Connecting systems so data and processes stop breaking halfway.
Server and environment upkeep plus technical support, as the base for Operate.
Scoped architecture reviews and IT decisions, usually part of Diagnose.
Detailed pages on custom software development in Indonesia are available as capabilities. Our identity stays Technology Partner.
Scenarios based on common industry problems, with the approach and architecture for each. Our client portfolio is published separately.
Search by industry, problem, or keyword.
Solution case studies do not refer to any client and are not MarkasDev portfolio items.

We have not locked a single vertical as our public focus yet. The candidates we are testing:
VetraFlow and related products are not offered publicly yet. We do not market products that are not ready to sell and operate.

For companies that have a market and a business model but do not want to fund development upfront. Send us your proposal. If it is approved, we build and run the product with you in a long-term partnership.
The stack for a specific project is settled during Diagnose. These five apply to every project:
Scope, assumptions, and acceptance are agreed before the build starts.
Development, staging, and production that stay consistent.
Sized to your scale, so alerts arrive before user complaints.
Runbooks your own team can follow, not only us.
A release path that does not break production.

Not finding your answer? Tell us about your situation in a first conversation.
We are a Technology Partner. Custom software development is a capability inside the Deliver phase, not our whole identity. We stay responsible until the system runs reliably after go-live.
A short first conversation to qualify the fit costs nothing. Discovery that produces findings, priorities, and a scope recommendation is a paid Diagnose.
Reactive maintenance usually fixes things only after they break. Operate is a retainer with clear responsibility, regular reporting, and controlled change. SLA details are agreed per contract.
No. We do not claim broad expertise we cannot back up. Our vertical focus is being chosen through market interviews and our real delivery capacity.
Probably not. We focus on systems that your operations depend on. For a simple brochure site, another vendor will suit you better.

A partnership program for companies that want to build a digital product or app without funding development upfront. You send a proposal. If it is approved, MarkasDev builds and runs the technology, and product revenue is shared under a long-term agreement. See the Startup Partner page for details.
Yes. We apply AI to processes that already run, such as document extraction, internal knowledge assistants, and customer service support. Every rollout starts with a Diagnose and a baseline so the efficiency gain can be measured. See AI implementation.
Describe the symptoms you see and what you have already tried. We will tell you whether Diagnose makes sense, or point you to a better route.
