Multi-agent pipeline using Claude-backed AI to process raw client bug reports: automated context enrichment, ephemeral environment reproduction, diagnostic PR generation, E2E test triggering, and conditional autonomous deployment.

Designed and delivered an AI-native bug resolution system that cut average developer cost per bug by 80%, with a growing subset of tickets now fully automated from client submission to merge-ready fix.

SanSec Ecomscan for malware pattern detection, Semgrep with Magento-specific security rulesets for static analysis, and Composer audit plus Trivy for dependency CVE scanning — all running as parallel CI jobs, blocking merge on findings, with Dependabot for continuous dependency monitoring.

Continuous security assurance without manual audit overhead. Compromised dependencies and security regressions are caught at the point they are introduced, not during a quarterly review. No compromised code has reached production via supply chain attack since adoption.

Two-layer patching system: a Composer meta-package that Dependabot PRs automatically across the portfolio when patches are released, and Ansible playbooks for initial mitigations. Deployed successfully against CosmicSting, Session Reaper, and Polyshell.

Managed stores were protected before exploits went public. Zero successful attacks against any managed store during major Magento vulnerability events. The framework turns a portfolio-wide security response from a days-long manual operation into an hours-long automated one.

Identified and responsibly disclosed vulnerabilities including CVE-2024-34102 (CosmicSting XXE in Adobe Commerce), stored XSS collections in Amasty and Mirasvit extensions, SQL injection in Pay360 Magento 1, and sensitive information disclosure across multiple merchants. Built the CosmicSting Validator tool — scanned 6,500+ stores, identified 2,300+ vulnerable.

Contributed to the security of the broader Magento ecosystem through responsible disclosure to Adobe and major vendors. Demonstrated the platform depth required to find issues that most engineers miss during normal development.

Automated daily database snapshots and weekly filesystem backups across all managed stores, tiered to cold storage after 30 days, with integrity verification (restore test + schema check) on every backup. Plus a sanitisation pipeline producing anonymised production dumps for developer use — real data shapes, no real PII.

Data protection compliance and developer productivity solved together. Every managed store has documented, verified backup coverage. Developers work with realistic data without the compliance overhead of handling real customer data.

Flexible Magento Hosting platform, supporting high availablity, autoscaling, multi-cloud deployments, and enterprise-grade performance. Deployed to your cloud of choice with Terraform and Ansible for infrastructure as code, and a multi-service architecture designed for resilience and cost optimisation.

Built a Magento hosting platform accessible to merchants who couldn't justify Adobe Commerce Cloud or enterprise pricing. Allowing for enabling smaller merchants to access Magento at reasonable cost, with the same reliability and performance as enterprise hosting.

Point-in-time incremental data sync to pre-provisioned target infrastructure, TTL pre-reduction, atomic DNS cutover with health-check-gated rollback capability, and 72-hour enhanced monitoring. Covers cPanel → containerised, Magento 1 → Magento 2, and cross-datacenter scenarios.

Clients moved from fragile single-point-of-failure hosting to resilient, maintainable infrastructure without downtime or data loss. Post-migration: improved performance, reduced operational risk, lower ongoing maintenance overhead.

Self-hosted Sentry (Docker Compose) for error tracking and performance monitoring, ELK Stack for centralised log aggregation, OpenVPN with certificate-based authentication for production access, and self-hosted GitHub Actions runners for compute-intensive CI jobs.

Replaced four SaaS subscriptions, savings £1,000s per month, with self-hosted equivalents without losing any capability. Operational overhead is minimal — all four tools are mature and stable in self-hosted form.

Shared Playwright E2E library with a core test suite covering Magento checkout, account, and catalogue flows, plus a per-store configuration and override layer. Runs in CI on every PR against the relevant store's staging environment.

Every managed store has regression coverage for its critical user journeys from day one — without the cost of building test suites individually per client. New stores inherit protection immediately.

Parallel CI jobs covering PHPStan, PHPCS, PHPUnit, APM baseline comparison (New Relic), Lighthouse CI Core Web Vitals delta, SanSec Ecomscan, Semgrep security analysis, and two-engineer peer review. All gates must pass before merge.

Shifted quality assurance left — issues caught in CI cost minutes to fix. Post-deploy production incidents from code regressions have dropped measurably since adoption. Quality is enforced by the pipeline, not by hope.

GitHub Actions webhook triggers Ansible provisioning of a containerised Magento stack (Warden-based) per PR, seeded from the anonymised production dump pipeline. Environment URL and admin credentials posted to the PR. Torn down automatically on merge or close.

Clients and QA can test every PR on a live working environment before it reaches production. Feedback arrives on real code, not screenshots. The development feedback loop for frontend and checkout changes compressed from days to hours.

GitHub Actions and Ansible pipeline covering pre-deploy validation (SCD, DB migrations, health checks), symlink-based atomic cutover, PHP-FPM reload without connection drop, and post-deploy APM and Varnish verification with automatic rollback on failure.

Removed deployment risk as a reason not to release. Failed deployments now roll back automatically in under 30 seconds before users are affected. Teams ship more frequently with higher confidence.

Warden-based containerised local development environments with service versions locked to match production exactly. Shared configuration repository, per-project override layers, anonymised production data sync CLI, and automated onboarding validation.

"Works on my machine" has been effectively eliminated as a debugging category. Environment-specific bugs and flaky tests caused by service version mismatches are no longer part of the team's workflow. New engineer time-to-first-commit significantly reduced.

Module scaffolding templates enforcing structural conventions by default, PHPStan at maximum level and PHPCS with custom Magento ruleset as CI gates, and a structured peer review process with defined sign-off requirements for security-sensitive code paths.

Raised baseline code quality across the team. Reduced technical debt accumulation rate, improved onboarding speed for new engineers, and reduced post-deploy incidents from inconsistent patterns. Quality enforced by tooling rather than review culture alone.
