Full-Stack Tech Lead / Architect (Angular + NestJS)

We are seeking a Full-Stack Tech Lead / Architect with deep expertise in Angular and Node.js/NestJS, who can define the architecture of enterprise-grade systems, lead technical standards, and mentor development teams.

This is a part-time consulting role ideal for engineers who already hold senior positions but want to influence system design, establish best practices, and guide teams on complex full-stack projects.

You will focus on strategic architectural decisions, ensuring scalability, maintainability, and high performance of front-end and back-end systems, while enabling your teams to deliver production-grade solutions.
 

⚙️ Tech Stack

Frontend: Angular 15–18 (TypeScript, RxJS, Signals, Reactive Forms)
Backend: Node.js with NestJS (modular, microservice-ready)
APIs: REST / GraphQL, JWT / OAuth2 authentication
Databases: PostgreSQL, MongoDB
Frontend Architecture: modular design, lazy-loaded modules, monorepo structures, state management (NgRx, Akita, Signals)
Backend Architecture: microservices, modular NestJS applications, event-driven patterns
CI/CD & DevOps: Git, GitHub Actions, Docker, Kubernetes
Observability: Prometheus, Grafana (or equivalents)
