Our Capabilities
Test Automation
We build automated test suites that catch bugs before your users do — enabling your team to ship faster with confidence. Our test automation covers unit tests (Jest, PHPUnit, pytest, NUnit) for individual functions and components, integration tests for API endpoints and service interactions, end-to-end tests (Cypress, Playwright) simulating real user workflows across the entire application, visual regression tests (Percy, Chromatic) detecting unintended UI changes, and accessibility tests (axe-core) verifying WCAG compliance automatically. We integrate all tests into your CI/CD pipeline so every code push is validated before it reaches staging or production. Our automation frameworks follow the test pyramid principle: fast, numerous unit tests at the base, fewer integration tests in the middle, and targeted E2E tests at the top — delivering comprehensive coverage without slow, flaky test suites.
Performance Testing
We identify performance bottlenecks before they impact your users — not after. Our performance testing includes load testing (k6, Artillery, JMeter) simulating expected and peak traffic patterns, stress testing to find the breaking point of your infrastructure, endurance testing to detect memory leaks and resource exhaustion over time, spike testing to validate auto-scaling behavior under sudden traffic surges, and database performance testing with realistic data volumes (not empty test databases). Every performance test produces a detailed report showing response times (P50, P95, P99), throughput, error rates, and resource utilization — correlated with specific code paths and database queries. We provide actionable optimization recommendations: which queries to index, which endpoints to cache, which services to scale, and what infrastructure changes will deliver the biggest improvement per dollar spent.
API Testing
We implement comprehensive API testing that validates your backend services work correctly, perform well, and remain secure. Our API testing covers functional testing (every endpoint, every parameter combination, every error case), contract testing (Pact) ensuring API compatibility between microservices, schema validation verifying responses match OpenAPI/Swagger specifications, authentication and authorization testing (token validation, role-based access, permission boundaries), rate limiting and throttle testing, and backward compatibility testing for API version migrations. For APIs serving external consumers (partners, mobile apps), we implement API monitoring that tests production endpoints every 5 minutes from multiple geographic locations and alerts your team within 60 seconds of any degradation.
Security Testing
We test your application for security vulnerabilities before attackers find them. Our security testing includes SAST (Static Application Security Testing) scanning source code for vulnerabilities, DAST (Dynamic Application Security Testing) probing running applications for exploitable weaknesses, dependency scanning identifying known vulnerabilities in third-party libraries, OWASP Top 10 validation (SQL injection, XSS, CSRF, broken authentication, and more), API security testing (authentication bypass, authorization escalation, injection attacks), and penetration testing for critical applications handling sensitive data. Security test results are delivered as a prioritized report with severity ratings (Critical, High, Medium, Low), proof-of-concept exploits, and detailed remediation instructions. We retest after fixes are implemented to verify vulnerabilities are properly closed.
CI/CD Quality Gates
We integrate quality gates into your CI/CD pipeline that prevent defective code from reaching production. Our quality gates include automated test execution (all tests must pass before merge), code coverage thresholds (minimum 70% for new code, increasing over time), static analysis (SonarQube, ESLint, PHPStan) enforcing code quality standards, security scanning (Snyk, Dependabot) blocking known vulnerable dependencies, performance budget validation (bundle size limits, API response time thresholds), and deployment verification tests that run against staging after deployment and against production after release. When a quality gate fails, the pipeline stops and the developer gets immediate feedback with clear instructions on what to fix. This eliminates the "move fast and break things" mentality and replaces it with "move fast and keep things working."
QA Strategy & Consulting
We help teams establish QA processes that match their development velocity and quality requirements. Our QA consulting includes test strategy development (what to test, how deeply, at what stage), test automation framework selection and setup, CI/CD pipeline quality gate configuration, QA team structure recommendations (embedded QA vs centralized, manual vs automation ratio), and training for development teams on testing best practices. For organizations transitioning from manual to automated testing, we provide a phased migration plan that starts with the highest-value automated tests (smoke tests, critical user flows) and gradually expands coverage without disrupting ongoing development.

Frequently Asked Questions
QA automation uses software tools to execute pre-scripted tests on your application automatically. This includes unit tests, integration tests, end-to-end tests, and performance tests. Automation catches regressions quickly and enables faster, more confident releases.
We use Selenium and Playwright for browser automation, Cypress for E2E testing, Jest for unit testing, Postman for API testing, JMeter/k6 for performance testing, and Appium for mobile testing. We select tools based on your project's technology stack.
Initial automation setup costs $5,000-15,000 depending on application complexity. Ongoing QA services range from $2,000-8,000/month. The investment typically pays for itself within 3-6 months through faster releases and fewer production bugs.
Yes, we provide independent QA services for applications built by any team. We start with a test assessment, create a test strategy, and implement automated and manual testing tailored to your application.
We configure automated tests to run on every code commit, pull request, and deployment. Tests are organized by speed: fast unit tests run first, then integration tests, then E2E tests. Failed tests block deployments automatically.
