● Design and implement full-stack features across the Angular frontend and PHP Symfony backend in a multi-repo architecture, from database schema and API design through to UI components and automated tests. ● Write and maintain PHPUnit unit and integration tests on the backend, and Angular/Jest component tests on the frontend. ● Investigate and fix production bugs including race conditions, Redis pub/sub failures, and Kubernetes pod issues in AWS EKS environments. ● Review API contracts between frontend and backend services, ensuring serialisation groups and API Platform denormalisation stay consistent. ● Manage feature branches using Git worktrees to enable parallel development without disrupting concurrent work. ● Delivered an end-to-end configuration toggle feature with tenant-level admin controls, including Doctrine entity column and migration, API Platform serialisation, Angular reactive form controls, and PHPUnit tests. ● Built a complete signal-matching pipeline with multi-tenant disambiguation, conditional gating based on network context, and hierarchical resolution shipped across backend and Angular admin UI. ● Traced an intermittent production incident where a third-party library upgrade broke pub/sub functionality on managed cache infrastructure, identified the root cause, and coordinated the fix via a Kubernetes secret update.

● Shipped two production features for diagrams and diagram management contributing to customer growth — covering new editing capabilities and management workflows. ● Rebuilt the user access-roles model for Diagrams end-to-end, replacing the previous permission logic across UI and API. ● Built a Google Docs-style Request Access page for users without view permission, including the request flow and approval surface. ● Developed and published an internal npm package, including local development workflow via npm link. ● Worked across Angular 16+ with Akita Store and RxJS, with incremental adoption of Signals in newer features. ● Drove UX/UI refinements across the app and collected customer feedback to validate expectations were met. ● Coordinated cross-team work where diagram features touched adjacent product areas, and partnered closely with QA on rapid fixes.

● Led a team building the Creative Management Platform (CMP) across digital advertising formats (Video, Rich, Display) on Angular frontend and Laravel backend. ● Migrated the platform from Angular 5 to Angular 14 in 2022 — removed deprecated libraries, applied trackBy, OnPush change detection, and lazy-loading for significant runtime performance gains. ● Built core ad-media builder functionality — the interactive editor used to create rich-media ads served across the web and apps. ● Built a NodeJS + Puppeteer (headless browser) service that generates screenshots automatically for ready-made ad banners. ● Extended platform mobile capabilities using Flutter. ● Mentored team members on Angular best practices and reviewed cross-team work to keep delivery on schedule.

● Delivered web applications and e-commerce sites across diverse client domains over eight years of contract work. ● Backend specialisation in NodeJS + MongoDB, with focus on data integrity and performance. ● Designed and built a cross-platform dating application for a UK client — iOS (Swift) and Android (Kotlin).
