Alexander Marfel
Frontend Tech Lead (React/Next.js, TypeScript) focused on repeatable releases and shared foundations. I build frontend platforms (UI kits, API SDKs, tooling) and CI practices (quality gates, versioning) for multi-app products.

What I bring
Calm execution and clean engineering decisions — from UI details to architecture and release quality.
Quick path: skim Projects, then reach out if the profile matches what you are hiring for.
How I work
A calm, production-first delivery style: understand constraints, ship the smallest correct thing, then iterate.

A small selection that reflects my delivery style: clarity, quality, and performance.

2024-10 — Present
Hybrid
Led frontend delivery for a multi-region product: Next.js App Router web shop, Vite-based user portal, and a shared frontend platform.
- Built a shared frontend platform (UI kit, core packages, type-safe API SDK, unified tooling) used across multiple apps.
- Introduced semver and a predictable release cadence for apps/packages (private registry publishing).
- Designed CI/CD “single build → promote” across environments/regions to keep releases artifact-based and traceable.
- Made CI checks (typecheck/lint/format) and build output tracking (bundle checks/metrics) part of the default delivery workflow.
- Owned releases across dev/test/prod: frequent deployments, support, and post-release fixes.
- Led planning, decomposition, code reviews, mentoring, and cross-team alignment (product/design/backend).
