What we audit
We look beyond surface issues. Below are the key directions we focus on:
Backend
- Code structure and readability
- Logic and error handling
- API design and versioning
- Microservices communication
- Performance under load
- Tech debt and outdated libraries
- Scalability and extensibility
Frontend
- Code modularity and organization
- State management strategy
- Reusability of components
- UI responsiveness and rendering time
- Browser compatibility
- Error handling in the UI
- Framework version issues
Infrastructure
- CI/CD pipeline quality
- Cloud configuration and resource usage
- Deployment and rollback processes
- Server environments and scaling
- Logging and monitoring practices
Database
- Schema design and normalization
- Query performance
- Indexing and constraints
- ORM usage patterns
- Scalability risks
- Data validation logic
Security
- Search for vulnerabilities (e.g., SQL injection, XSS, CSRF)
- Review of authentication and authorization logic
- Data encryption and storage safety
- Session and token handling
- Use of vulnerable libraries
- Access control policies
UI/UX
- Navigation and user flow
- Accessibility (contrast, keyboard navigation, etc.)
- Feedback elements (loading states, confirmations, etc.)
- Layout clarity
- Bottlenecks in user actions
Code review services we offer
SAST – Automated security code review
Encryption errors:
- weak encryption algorithms or strong encryption algorithms with weak implementation (e.g., insecure key storage).
- Code injection vulnerabilities.
- XSS (cross-site scripting) vulnerabilities.
Manual security-focused code review
- Auditing and logging mechanisms.
- Input/data validation mechanisms.
- Impersonation/delegation mechanisms.
- Session management.
- Communication security.
- The security of connection strings.
- Input/output operations security.
- The presence of serialization filtering.
- Reflection mechanisms.
- The presence of obfuscation.
- Checking if the code is thread-safe.
All-around code review
In addition to SAST and manual review of code security, we check:
- If descriptive names for code variables are in place.
- If comments about what particular code functions and methods do are present.
- If documentation on what the whole code does and what its dependencies are is in place.
- If the developers can take advantage of ready frameworks and reusable components to get work done faster.
- If the practice of splitting code into shorter units is observed.
- If the code is portable.
- If effective version control is implemented.
- If linter tools (SonarQube, ESLint) are used.
- If exception-handling mechanisms are effective.
- If the required security mechanisms are in place, and more.

Let us help you match your needs to the right type of audit. We’ll guide you through the options and recommend what fits best.
AI-enhanced code review & development
AI won’t replace a human expert, but it can be a smart assistant when used right.
Our engineers use AI tools to generate sample unit tests for uncovered logic, speed up documentation and code summarization, help write mock data generators, suggest potential refactoring ideas, and auto-generate code snippets for repetitive patterns.
This means faster reports, better coverage, and examples you can immediately use. We also offer the following AI services:
AI development
- Generative AI
- Natural Language Processing (NLP)
- Computer vision
- Recommendation systems
- Predictive analytics
- Audio processing
- Custom AI-powered tools
AI consulting
- Code security analysis with AI tools
- Smart linting
- AI-driven code suggestions
- Custom research
- Data preparation and quality checks
- AI readiness assessments for products or teams
