What I'm looking for

I want to lead end-to-end full-stack delivery as a tech lead—owning architecture, CI/CD, and observability—using AI tooling with guardrails and tight BRD→spec alignment to keep quality high and release cycles predictable.

With 10+ years in web engineering, I lead end-to-end delivery on large JavaScript/TypeScript systems and use Python for scripting, automation, and tooling—especially micro-frontends, shared component libraries (Storybook, Rollup), and modern data layers (TanStack Query). I drive CI/CD with GitHub Actions, containerisation and cloud-native deployment patterns (Docker/Kubernetes), and production readiness through observability (Sentry, Datadog, New Relic) with PagerDuty-style alerting.

As a tech lead and Engineering Manager, I improve team throughput through clear architecture (including sequence diagrams), Confluence documentation, and BRD → technical specification alignment and stakeholder communication. At TheTransformationGlobal I led full-stack delivery for the Centro portal, migrated modules from JavaScript to TypeScript, standardized frontend patterns, built and governed a Storybook + Rollup library, and raised quality with Cypress and Playwright—while using AI tooling (including MCP/IDE agents with guardrails) to shorten POC cycles and keep delivery predictable.
