Rigorous functional and exploratory testing to validate that every feature behaves as intended across all scenarios.

Functional Testing

QA Testing

Comprehensive manual and exploratory testing to catch bugs before they reach your users. Our QA engineers become an extension of your team.

Intelligent automation frameworks that integrate seamlessly with your development workflow to accelerate delivery.

Automation & Efficiency

Test Automation

Build robust automated test suites that integrate with your CI/CD pipeline, reducing regression risk and accelerating release cycles.

Performance, security, and accessibility testing to ensure your application holds up in the real world.

Non-Functional Testing

Performance Testing

Identify bottlenecks and validate scalability before they impact real users. Load testing, stress testing, and performance optimisation.

Security Testing

OWASP-aligned penetration testing and vulnerability assessments that protect your application and your users' data.

Accessibility Testing

WCAG 2.2 compliance testing and remediation to ensure your product is usable by everyone, meeting legal obligations and expanding your audience.

Expert consultancy to transform your quality engineering practices and build sustainable testing capabilities.

Strategy & Advisory

QA Consulting

Strategic QA consultancy to help you build a quality culture, optimise your testing processes, and reduce the cost of poor quality.

Bugs discovered in production cost 100x more to fix than those caught during development. A structured QA process with experienced engineers systematically prevents this escalation.

Defects Reaching Production

Without dedicated QA resource, edge cases and cross-browser scenarios are routinely missed. Our engineers design coverage strategies that address your specific risk profile.

Insufficient Test Coverage

Poorly structured testing becomes a bottleneck. We design efficient testing processes that accelerate releases rather than gate them.

Slow Release Cycles

Generic testing misses business-critical scenarios. We assign engineers with direct experience in your industry to ensure domain-specific coverage.

Domain Knowledge Gaps

Expert manual QA testing services from senior engineers with 8+ years experience. Functional, regression, and exploratory testing integrated with your sprint cycle.

User Acceptance Testing

Cross-Browser Testing

API Testing

Flaky tests that pass and fail unpredictably undermine confidence in your entire test suite. We build robust automation using stable locator strategies, dynamic waits, and proper test isolation.

Brittle Test Suites

Poorly architected automation becomes expensive to maintain as the application evolves. We apply software engineering principles to testing code: abstraction, modularity, and clear separation of concerns.

High Maintenance Overhead

Test suites that take hours to run block your delivery pipeline. We implement parallel execution, intelligent test selection, and pipeline-native reporting to keep feedback loops fast.

Slow CI/CD Pipelines

Many automation projects optimise for coverage metrics rather than confidence. We design test strategies that prioritise high-risk user journeys and business-critical flows.

Coverage Blind Spots

Expert test automation using Playwright, Cypress, and Selenium. Maintainable frameworks with CI/CD integration. 85% average regression coverage achieved.

CI/CD Integration

Most teams don't know how many concurrent users their application can handle before degradation begins. We establish your capacity baseline and break points before real users find them.

Unknown Capacity Limits

Without automated performance gates, code changes can silently degrade response times. We integrate performance benchmarks into your pipeline to catch regressions at commit time.

Performance Regressions in CI/CD

Seasonal events, marketing campaigns, and viral moments create traffic spikes that differ dramatically from average load. We model realistic peak scenarios to validate your auto-scaling configuration.

Unpredictable Peak Load

Performance issues frequently sit in databases, caching layers, or third-party integrations rather than application code. Our analysis identifies the actual constraint, not just the symptom.

Infrastructure Bottlenecks

Load testing, stress testing, and performance optimisation using k6 and JMeter. We've simulated 5M+ concurrent users. Identify bottlenecks before they hit production.

API Performance Testing

Performance Monitoring Setup

Automated scanners catch known CVEs but miss business logic flaws, insecure direct object references, and chained vulnerability exploits. Manual penetration testing by experienced engineers finds what tools miss.

Undetected Vulnerabilities

PCI DSS, SOC 2, ISO 27001, and FCA requirements mandate regular security assessments with documented evidence. We provide the reports and remediation evidence your compliance programme needs.

Regulatory Compliance Requirements

Enterprise customers and procurement teams require security assessment evidence before signing contracts. Our assessments are structured to satisfy vendor security questionnaires and third-party audit requirements.

Enterprise Sales Blockers

APIs are the most frequent attack vector in modern applications, yet often receive less scrutiny than the user interface. We conduct dedicated API security assessments aligned to the OWASP API Security Top 10.

API Security Gaps

CREST-certified penetration testing, OWASP Top 10 assessments, and SAST/DAST analysis. We've helped 100+ organisations pass enterprise security assessments and achieve compliance.

Security Code Review

The UK Equality Act, Public Sector Bodies Accessibility Regulations, and the European Accessibility Act (effective 2025) impose legal obligations. Organisations face enforcement action and litigation risk from unaddressed accessibility failures.

Legal Compliance Risk

Axe, WAVE, and Lighthouse identify some WCAG failures but miss complex keyboard navigation issues, screen reader compatibility problems, and cognitive accessibility barriers that require manual expert evaluation.

Automated Tools Miss 60–70% of Issues

Accessibility failures in shared components propagate across every page that uses them. We identify systemic issues at the component level to maximise remediation efficiency.

Component Library Propagation

Most development teams have limited accessibility expertise, leading to recurrent failures. We provide remediation workshops and integrate accessibility checkpoints into your development workflow.

Developer Accessibility Knowledge Gaps

WCAG 2.2 AA/AAA compliance testing using JAWS, NVDA, and VoiceOver. Automated tooling plus manual expert testing. 100% compliance achieved for NHS and public sector clients.

Remediation Support

Accessibility Training

If bugs are consistently reaching production, the root cause is usually systematic rather than one-off. We identify the process gaps, architecture weaknesses, and cultural patterns that enable defects to slip through.

High Defect Escape Rate

When testing becomes a gate rather than an integrated activity, release cycles slow and quality degrades. We redesign testing processes to be embedded, continuous, and enabling rather than blocking.

QA as a Bottleneck

Hiring and structuring a QA function from scratch requires expertise most engineering leaders don't have. We define the roles, competency frameworks, tooling stack, and hiring criteria to build a high-performing quality organisation.

Building an Internal QA Team

Moving testing earlier in the development lifecycle requires cultural change, not just tooling adoption. We facilitate the organisational change alongside the technical implementation.

Implementing Shift-Left Testing

Strategic QA consulting to reduce defect escape rates, implement shift-left testing, and build high-performing QA teams. Average 4x ROI on quality investment.
