Project Background

Evolving enterprise no-code platforms to meet complex business requirements

Our client, a provider of innovative enterprise solutions, had been offering a powerful no-code tool enabling organizations to build business applications without writing code. While this approach simplified development, consultants often faced limitations when trying to implement complex, scenario-specific logic.

To address this gap, the client initiated a project to evolve the tool from a purely no-code platform to a low-code environment. The vision was to empower consultants with a Domain-Specific Language (DSL) that combines the simplicity of no-code with the flexibility of traditional coding.

The Challenge

Our Solution

DSL Architecture & Features

Data Types & Operations

String, Integer, Decimal

Date, Boolean, List

Record types

Arithmetic operators

Relational & logical operators

String manipulation

Control Structures

IF/ELSE conditions

SWITCH statements

Error handling

FOR loops

FOREACH iterations

Decision-making logic

Advanced Methods

General utilities (Concat, IsEmpty)

Type casting functions

API methods (CRUD operations)

Webhook creation/execution

LINQ methods (Add, Remove, Where)

List manipulation (Distinct, etc.)

Critical Functionality: Dynamic Code Execution

The revolutionary architecture that enables seamless DSL-to-C# transpilation and execution

Execution Architecture Flow

DSL Creation

Consultants write business logic using our custom DSL syntax

Transpilation

DSL constructs automatically converted to executable C# code

Storage

Generated C# code stored securely in database with metadata

Runtime Fetch

Platform retrieves stored function by formula name at execution time

Secure Execution

Code executed using Roslyn scripting with strict security controls

Dynamic Execution Process

Database Storage

DSL constructs transpiled into executable C# code and stored in database with versioning

Dynamic Fetching

Runtime retrieval of stored function by formula name with caching optimization

Model Generation

Dynamic input/output models generated, mapping user-provided parameters

Secure Execution

Roslyn CSharpScript execution with controlled assembly and namespace references

Response Handling

Results serialized to JSON with structured success/error responses and compilation feedback

Business Impact & Results

Transforming consultant productivity and platform capabilities

For Consultants

Dramatically simplified writing complex scenarios without requiring full-scale coding expertise. Consultants can now implement advanced business logic with familiar, domain-specific syntax while maintaining the rapid development benefits of no-code platforms

For Businesses

Significantly faster application development cycles with improved flexibility and customization capabilities. Organizations can now handle complex business requirements that were previously impossible with pure no-code solutions.

For the Platform

Successfully strengthened market position as a hybrid no-code/low-code platform, differentiating from competitors and opening new enterprise market segments requiring advanced customization capabilities.

Real-World Use Cases

Practical applications demonstrating DSL flexibility and power

Automated Error Handling

Complex error detection and resolution logic in record creation processes, with custom validation rules and automated recovery mechanisms.

Flexible Workflow Management

Dynamic business process flows using advanced IF/ELSE and SWITCH logic, enabling context-sensitive decision making.

Data Processing & Iteration

Sophisticated customer data processing using FOR and FOREACH loops with custom business rules and calculations.

Real-Time Integrations

Dynamic webhook execution for real-time system integrations, with custom payload processing and response handling.
