Vibe Coding: Rapid Software Development with Security and Quality
Executive Summary
A mid-sized company needed time-tracking software for 150 employees. Traditional solutions: €9,000-15,000/year. With DeViLink's Vibe Coding approach: €3,500 one-time – perfectly integrated into existing systems.
Vibe Coding is the new development methodology using AI assistants like Claude Code. But: Uncontrolled "vibing" is dangerous. We show you how to do it right.
What is Vibe Coding?
Vibe Coding is a term coined in 2025 by AI pioneer Andrej Karpathy and named "Word of the Year" by Collins English Dictionary. It describes a new approach to software development where developers collaborate with AI assistants like ChatGPT, Claude Code, Cursor, or GitHub Copilot.
In classic Vibe Coding, the developer describes what they want to build to a Large Language Model (LLM). The AI then generates code that the developer accepts without deep understandingand evaluates only through execution results.
The Danger of Uncontrolled Vibe Coding
41% of all code lines written globally today are AI-generated. Without quality control, this leads to security vulnerabilities, performance issues, and unmaintainable code.
Advantages & Risks: The Truth About Vibe Coding
Advantages

The Solution: Controlled Vibe Coding with Quality Assurance
At DeViLink, we combine the speed of Vibe Coding with professional review processes, experienced developers, and proven security concepts.
When Should You Use Vibe Coding?
Not every project is suitable for Vibe Coding. We've developed three clear categories:
1Ideal for Vibe Coding
- Internal Tools & Automation: CRM integrations, Excel automation, data import scripts
- Prototypes & MVPs: Fast validation of business ideas
- Admin Dashboards: Internal management tools without public access
- API Integrations: Connecting existing systems
Our Approach: Generation + Peer Review + Manual Testing
2Vibe Coding with Extended Tests
- Business Software: Longer lifespan, multiple users
- Client Projects with Maintenance: Software that will be further developed
- Lead Generators: Forms, calculators (like our Pentest calculator)
Our Approach: Vibe Coding + Automated Tests + Code Review + Security Audit
3Professional Development (not Vibe Coding)
- Critical Business Systems: ERP, financial software, HR systems
- Public Web Applications: E-commerce, SaaS products
- Highly Complex Architectures: Microservices, distributed systems
Our Approach: AI-assisted development with full software engineering process
DeViLink's Vibe Coding Process: Speed with Security
Our hybrid model combines German consulting quality with Vietnamese developer teams and AI support:
Requirements Analysis (Germany)
Our German consultants discuss your goals, understand your business processes, and create a clear development plan.
Rapid Development (Vietnam)
Our experienced Vietnamese developers use AI tools like Claude Code, Cursor, or GitHub Copilot to generate code in proven patterns and programming languages they know inside and out.
Quality Assurance
Every line of code is reviewed. Our senior developers check:
- Security (OWASP Top 10, SQL Injection, XSS, CSRF)
- Performance (Database queries, caching, load times)
- Code Quality (Readability, best practices, maintainability)
- GDPR Compliance (Data protection, cookie banners, consents)
Fast Hosting & Feedback
Within 2-3 days you'll have a working demo that we can test and adjust together.
Secure Deployment
Your application is protected by external security measures:
- VPN Access for internal tools (employees only)
- Firewall Rules (IP whitelisting, rate limiting)
- WAF (Web Application Firewall) for public applications
- Monitoring & Logging for security incidents
Real-World Examples: Where We Use Vibe Coding
Salesforce Email Automation for Microsoft 365
Challenge: A client wanted to automatically forward incoming emails in Microsoft 365 to Salesforce based on spam filter rules.
Solution: Automation script using Microsoft Graph API and Salesforce REST API. Intensive testing due to complex email rules and error handling.
Time-Tracking Software for 150 Employees
Challenge: Mid-sized company needed time tracking. Standard software: €9,000-15,000/year. Budget too high.
Solution: Custom web application with perfect integration into existing systems (Active Directory, Excel export, project assignment).
Lead Generators & Calculators
Challenge: Clients want to generate qualified leads through their website. Simple forms are not enough.
Solution: Interactive calculators (like our Pentest Calculator), which engage prospects and provide immediate price indicators.
Typical Use Cases for Vibe Coding
Data Import & Export
CSV/Excel to database, API sync, ETL processes
Workflow Automation
Email notifications, approval processes, scheduled jobs
Reporting & Dashboards
Internal analysis tools, KPI dashboards, data visualization
API Integrations
CRM connectors, payment systems, marketing tools
Admin Panels
Content management, user administration, system configuration
