CREATE! - Austrian Standards Platform

Project Overview

CREATE! was a comprehensive enterprise platform for Austrian Standards, designed to modernize and digitize the entire standards management lifecycle. As a Senior Software Developer, I led the development of critical system components for managing technical standards, compliance documentation, and certification processes.

The Challenge

Austrian Standards needed to modernize their legacy systems:

• Paper-based Processes: Manual handling of standards documentation
• Legacy Systems: Outdated technology stack with limited scalability

Technical Implementation

Backend Architecture

@RestController
@RequestMapping("/api/standards")
public class StandardsController {
    
    @Autowired
    private StandardsService standardsService;
    
    @GetMapping("/{id}")
    public ResponseEntity<StandardDto> getStandard(@PathVariable Long id) {
        StandardDto standard = standardsService.findById(id);
        return ResponseEntity.ok(standard);
    }
    
    @PostMapping
    @PreAuthorize("hasRole('STANDARD_EDITOR')")
    public ResponseEntity<StandardDto> createStandard(@RequestBody CreateStandardRequest request) {
        StandardDto created = standardsService.create(request);
        return ResponseEntity.status(HttpStatus.CREATED).body(created);
    }
}

Database Design

• Standards Schema: Comprehensive data model for standards
• Audit Tables: Complete change tracking and history
• Performance Optimization: Strategic indexing and query optimization
• Data Integrity: Foreign key constraints and validation rules

Frontend Components

@Component({
  selector: 'app-standard-editor',
  templateUrl: './standard-editor.component.html'
})
export class StandardEditorComponent implements OnInit {
  standardForm: FormGroup;
  
  constructor(
    private fb: FormBuilder,
    private standardsService: StandardsService
  ) {}
  
  ngOnInit(): void {
    this.initializeForm();
    this.loadStandardData();
  }
  
  saveStandard(): void {
    if (this.standardForm.valid) {
      this.standardsService.saveStandard(this.standardForm.value)
        .subscribe(response => this.handleSaveSuccess(response));
    }
  }
}
