Custom Application Development

Secure, high-performance software tailored to your workflow — running on Windows, Linux, macOS and the web from a single codebase.

Done Dynamics builds custom desktop and cross-platform applications: internal enterprise tools, ERP panels, field operation apps, POS systems and hardware-integrated software. We run the same codebase on Windows, Linux, macOS and the web, and ship code signing, auto-update and hardware integration as defaults — not just design+code, but a working, signed, distributed system.

Platforms

Windows, Linux, macOS and web — from one team

We do not ask what device your users are on — your application performs the same on each.

Windows

Native installs on Windows 10 and 11, MSI and MSIX packaging, Active Directory integration, enterprise-signed releases.

Linux

.deb, .rpm and AppImage builds for Debian, Ubuntu, Red Hat, Fedora and Arch. Can run as a system service.

macOS

Native, Apple-signed and notarized apps for Apple Silicon and Intel Macs, delivered as .dmg.

Web

Browser build from the same codebase. No install, accessible from any device — fast and modern.

Why custom?

If the package does not fit you, we write one that does

Every company runs differently. Custom software supports your process as it is — and grows with you as you scale.

  • One codebase, four platforms

    The same core runs on Windows, Linux, macOS and the web. Your maintenance cost does not double or triple.

  • Native speed and native hardware

    Software that does not get stuck behind browser limits — direct access to disk, USB, printer, camera and serial port.

  • Works offline

    Your app does not stop when the connection drops. Data is held locally and syncs back when the network returns.

  • Custom-fit, not packaged

    You do not bend your workflow to a generic SaaS. The software fits your process, not the other way around.

  • You own it

    Source code, package signing identities and distribution channels belong to you. No vendor lock-in.

  • Production-grade stack

    Electron, Tauri, .NET MAUI, Flutter Desktop and Qt — we pick the right framework with you.

Use cases

What we can build

From internal enterprise tools and field apps to ERP panels and POS systems.

Internal Enterprise Software

Custom apps that automate company workflows so employees finish work from a single screen.

ERP & Admin Panels

Scalable panels that unify stock, orders, production, finance and customer data in one interface.

Field Operations Tools

Offline-capable apps that technicians, couriers and dealers can use from phone and laptop in the field.

Data Capture & Analytics

Desktop and web tools that pull from multiple sources, process in real time and report.

Hardware Integration

Software that talks directly to local hardware — barcode readers, scales, printers, IP cameras and sensors.

POS & Point of Sale

Offline-resilient, fast, touch-friendly point-of-sale and checkout apps.

Security

Secure and strong — not a slogan, a checklist

Security in a desktop app is less visible than in a browser; that is why every item is made explicit.

  • Code signing: Windows, macOS and Linux packages are signed with an enterprise certificate — no "unknown publisher" warnings.
  • Encrypted local data: sensitive data is stored on the user device with AES-256.
  • Secure transport: server traffic runs over TLS 1.3 with certificate pinning.
  • Least privilege: the app only requests the files, network and system permissions it actually needs.
  • Auto-update: security patches roll out without user action, signed and verified.
  • KVKK & GDPR aligned: data retention, consent and deletion flows are designed to the legal frame.
Process

From idea to signed packages

Five phases, each with visible output.

  1. 01

    Process Analysis

    We observe your workflow on-site. Which step is manual, which step should be automated — written down clearly.

  2. 02

    Platform Decision

    Which platforms are mandatory, which are nice-to-have — decided from your user device inventory.

  3. 03

    Architecture & Prototype

    Data model, offline sync, hardware integration and security architecture validated by a prototype.

  4. 04

    Development

    TDD, code review and continuous delivery. Every build is signed and pushed to its release channel automatically.

  5. 05

    Distribution & Support

    Auto-update infrastructure, crash reporting and remote diagnostics. We see the bug before the user does.

Custom software — operational applications, integrations and SaaS

When does custom software actually make sense?

If off-the-shelf CRM software, ERP software or accounting software covers 80% of your need, packaged solutions are usually the right call. But if the remaining 20% of your operation is where your competitive advantage lives — a proprietary calculation, an industry-specific workflow, or a middle layer that makes multiple systems talk to each other — that is exactly where custom software earns its place. This is the work Done Dynamics does most often: SaaS development projects that integrate with off-the-shelf systems but are tailored to your business.

Typical engagements: field data-capture applications, reporting dashboards, B2B portals, bridges between e-commerce platform and accounting software, and inventory management software + ERP integrations.

Process, technology and delivery

Every engagement begins with a scope document: what will be built, what will not, which systems it will integrate with, which metrics we will measure against. On the technology side we use NestJS + PostgreSQL on the backend, Next.js or Flutter on the frontend, and authentication, observability and backup layers from our product backbone by default.

Regionally, Alanya software, Antalya software and Istanbul software projects dominate, but our remote-delivery model gives us clients across Türkiye and abroad as well. Share your need through the contact form.
