Custom software development
We build web, mobile, and microservice applications that scale. From MVP to mission-critical systems.
What we build
Web applications, iOS and Android mobile apps, internal platforms and integrations between systems. Some delivered projects:
- An offline-capable mobile app to record home visits to families with children aged 0 to 5 in rural areas, for UNICEF and INAIPI.
- Creciendo Juntos, INAIPI's app where parents and guardians log their children's development milestones, available on the App Store and Google Play.
- The INAFOCAM portal redesign, compliant with NORTIC B2:2017 and WCAG, plus an app to apply for and track teacher scholarships.
- A Moodle virtual classroom to train teachers nationwide during the pandemic, run as a managed service for 12 months, for COMPITE and UNDP.
Who it is for
For mid-size and large companies whose processes still live in spreadsheets, email and paper, or whose systems don't talk to each other. And for public institutions and international organizations that must meet accessibility standards and bring their digital services to the whole country.
Capabilities
Integration with what you already use
Few companies start from scratch. We connect new software to what already works: QuickBooks, your ERP, your CRM or an existing database. We also integrate payment gateways for e-commerce. And if you want an agent answering on WhatsApp with that data, GDT builds that too: see AI Agents.
How we work
Discovery. We understand the process and who will use the system.
Scope. We define what goes into the first version and what waits.
Incremental delivery. You see working progress, not just reports. An MVP takes at least 3 months, and a complete system usually takes 6 to 12 months.
Go-live and training. We train the team that will use the system.
Support. One year of support and maintenance included, renewable.

Frequently asked questions
How much does custom software cost?
It depends on scope, integrations and platforms (web, mobile or both). A custom system starts at US$15,000, and we have built systems of up to US$500,000. After a 30-minute call we give you an estimate.
How long does a project take?
An MVP takes at least 3 months, and a complete system usually takes 6 to 12 months. We agree on it during scoping, before coding starts.
Do I own the code?
Yes. The code belongs to the client.
Can you integrate it with QuickBooks or the ERP I already use?
Yes. Integrating with QuickBooks, ERPs and CRMs is part of what we do, through their APIs. If your system has no API, we build the integration as custom work, which adds time and cost.
Do you build apps that work offline?
Yes. The home-visit app for UNICEF and INAIPI lets field staff record visits and fill in forms with no connection, then syncs the data when the signal returns.
Do you work with public institutions?
Yes. We have delivered projects for INAIPI and INAFOCAM, including a portal compliant with NORTIC B2:2017 and WCAG. GDT is a registered State Supplier in the Dominican Republic (RPE 75304).
Do you provide support after delivery?
Yes. Every system includes one year of support and maintenance, renewable. For example, the virtual classroom for COMPITE and UNDP ran as a managed service for 12 months, with a help desk for facilitators and teachers.
