About the technology
Delphi at a glance
Delphi is Embarcadero’s development environment and programming language for building compiled applications with Object Pascal. It is known for fast native performance, visual form design and productive database access. Companies still rely on Delphi for operational software where stability, rich desktop interfaces and direct access to local resources matter.
Applications it supports
Delphi specialists deliver software that runs critical business processes across manufacturing, logistics, healthcare, finance and public administration. Common assignments include:
- Maintaining Windows desktop applications used by internal teams
- Creating database-backed tools for orders, inventory and production
- Extending point-of-sale, laboratory and industrial control software
- Building cross-platform mobile or desktop interfaces with FireMonkey
Ecosystem and tooling
The Delphi ecosystem includes the VCL framework for Windows applications and FireMonkey for cross-platform user interfaces. Specialists work with RAD Studio, Object Pascal, REST clients, component libraries and database layers such as FireDAC. They may also connect Delphi systems to SQL Server, PostgreSQL, Oracle, web services, message brokers and cloud APIs.
When outside expertise helps
Companies often bring in freelance Delphi expertise when a long-running application needs a safe modernization path rather than a disruptive rewrite. Typical needs include replacing outdated components, moving code to supported Delphi releases, improving test coverage, or separating tightly coupled modules. In Germany, remote collaboration is common, while regulated or plant-based environments may still require on-site workshops and German-language communication.
Signs you need a specialist
The right professional can quickly clarify risks in a legacy codebase and turn them into a practical delivery plan. Look for experience with:
- Upgrading older Borland Delphi code to current Embarcadero Delphi
- Refactoring large VCL applications without interrupting operations
- Diagnosing memory, threading and performance problems
- Integrating legacy desktop software with modern APIs
- Preparing builds, installers, deployment and support processes
What strong professionals bring
Strong Delphi professionals understand both Object Pascal and the business rules embedded in mature applications. They ask how data, users and connected systems behave before changing the code. They document dependencies, protect database integrity and introduce improvements in controlled steps. Their value lies in making existing software easier to maintain while delivering measurable progress on the current project.
Frequently asked questions
What clients ask us most about Delphi — answered in short.
Delphi is mainly used for native Windows desktop applications, database-backed business systems and operational tools. It is also used with FireMonkey for selected cross-platform desktop and mobile projects.
Delphi produces compiled native applications and offers visual development through the VCL, which can make desktop work efficient. .NET and Java usually provide broader modern ecosystems, so the best choice depends on deployment targets, existing code, team skills and integration needs.
A strong Delphi specialist often brings Object Pascal, VCL, FireMonkey, FireDAC and SQL expertise. Experience with REST APIs, Windows services, source control, automated testing and deployment is also valuable for production systems.
The required background depends on the codebase and the delivery goal. Embarcadero Delphi specialists should understand legacy components and older Object Pascal conventions when maintaining an established application, while a new project may need stronger skills in architecture, testing and integrations.
Yes, many Delphi tasks can be completed remotely through shared repositories, issue tracking, video calls and controlled test environments. On-site work can still help when the system interacts with factory equipment, local networks or sensitive operational processes.
Ask for examples of Delphi applications the specialist has maintained or delivered and discuss the technical decisions behind them. Check how they handle database changes, memory management, threading, testing, release planning and documentation rather than judging only by familiarity with the language.
Borland Delphi remains relevant because many established business systems depend on its compiled applications and mature component libraries. A specialist can assess whether to upgrade, refactor, isolate or gradually replace parts of the system instead of forcing an immediate full rewrite.
A Delphi modernization may include updating the toolchain, replacing unsupported components, improving architecture and adding automated tests. It can also involve exposing business functions through APIs, strengthening deployment and connecting the application to current databases or services.
The average hourly rate of freelancers in Germany who have used Delphi in their recent projects is 95 €, which corresponds to a daily rate of about 760 € based on an 8-hour working day.
