Test-Driven Development

90%+ coverage target with unit, integration, contract, and E2E tests in CI/CD pipeline.

  • Unit & integration testing
  • Contract testing (Pact)
  • E2E with Playwright
  • Mutation testing & quality gates

Zero-Downtime Deployments

Blue-green, canary, feature flags—automated rollbacks and observable releases.

  • Blue-green & canary deployments
  • Feature flags & progressive delivery
  • Automated rollback on SLO breach
  • GitOps with ArgoCD/Flux

Security by Default

SAST/DAST in pipeline, dependency scanning, secrets management, compliance-ready.

  • SCA & dependency scanning
  • Secrets management (Vault)
  • OWASP ASVS compliance

Observability Built-In

Structured logging, distributed tracing, metrics, alerting—SRE practices from day one.

  • OpenTelemetry instrumentation
  • Distributed tracing (Jaeger)
  • Metrics & alerting (Prometheus/Grafana)
  • Structured logging (ELK/Loki)

Knowledge Transfer

Documentation, ADRs, runbooks, team training—your team owns the code.

  • Architecture Decision Records (ADRs)
  • Runbooks & playbooks
  • Developer onboarding guides
  • Hands-on team training

We don't just write code—we engineer systems. Our development approach combines clean architecture, test-driven development, and DevOps automation to deliver software that's maintainable, observable, and ready for enterprise scale. From greenfield products to legacy modernization, we bring 15+ years of engineering excellence to every engagement.
