Moustafa Ellithy

I’m a Senior Frontend Engineer with 7+ years designing and building production systems across enterprise SaaS, government, and freelance client platforms. I specialize in frontend platform work—building reusable component systems and flexible service layers that other teams can adopt quickly. I’m comfortable owning projects end-to-end, from architecture and implementation through code review, release, and production deployment.

At GAMP, I solo-architected and built a 24-package publishable Angular component platform inside an Nx monorepo, adopted by 3 production apps and 10+ engineers. I reduced per-project CI pipeline time by ~10 minutes while sustaining 83% test coverage workspace-wide. I also stopped backend changes from breaking internal component packages by redesigning how packages connect to backend data using reusable TypeScript contract patterns.

I rebuilt shared UI foundations to make customization and maintenance easier—like replacing the data-table with TanStack Table’s flexible foundation and consolidating overlapping form controls (cutting ~1,060 lines across 57 files). I built shared services (auth, translation, realtime, user preferences, maps) using a reusable DI-token and ports-and-adapters pattern, enabling each app to use its own version without changing feature code. I held merge/release-approval authority and owned frontend code review, serving as a primary reviewer on 190+ merge requests and authoring the team’s MR review template.

Before that, as an Engineering Officer at the Ministry of Interior of Egypt, I led design, development, and deployment of 7 full-stack internal government systems (ASP.NET Core/C#, Vue/React, EF Core, SQL Server), including deployment on internal IIS/Windows infrastructure. I delivered real-time mapping and microservices with SignalR, built offline-capable notification software, and rebuilt custody tracking and requisition tools spanning multiple backend rewrites and frontends. In freelance work, I deliver end-to-end experiences—from bilingual admin workflows and OTP-based login to RTL-aware Next.js/React builds—while keeping a strong focus on quality, testing, accessibility (WCAG), and performance.
