LCNC Platform Experience

Experience designing and implementing drag-and-drop builders (e.g., visual editors, form builders, workflow designers) - Advantage

Experience building end-to-end low-code / no-code platforms, including visual modeling, rule engines, and runtime execution layers - Advantage.

Core Idea in LCNC Context

In an LCNC platform, end-users compose applications by dragging/dropping/recombining blocks (pre-built components with their own data schema, UI, validation rules, permissions, etc.). When a user connects a "User Profile" block with a "Billing Info" block (and maybe a "Custom Metadata" block), the platform must:

1. Dynamically compute the resulting data shape (merged schema).
2. Preserve all metadata (decorators, validation rules, OpenAPI extensions, UI hints, relations, etc.).
3. Generate runtime artifacts efficiently: TypeScript interfaces for backend services, JSON Schema for forms/validation, GraphQL types, database migrations, etc.
4. Do it at scale without exploding memory or compile time.

For a Team Lead role on a Low-Code/No-Code (LCNC) platform, this question is not just a syntax check. The interviewer is testing your architectural vision for metadata-driven development, visual modeling, and system scalability.

In an LCNC platform, you are building the blocks that other people use to build applications.

Why It Matters for a Low-Code/No-Code Platform

• Visual Schema Composition: LCNC platforms rely on users dragging and dropping blocks (e.g., combining a "User Profile" block and a "Billing Info" block). IntersectionType() is exactly how you dynamically merge those two visual schemas on the backend into a single, valid API contract.
• Dynamic Metadata Generation: Your platform must automatically generate API documentation and forms based on user layouts. You need utilities that preserve decorator metadata at runtime to achieve this.
• Performance and Memory: Creating thousands of distinct, hardcoded classes for every user configuration wastes server memory. Class composition helpers allow you to create dynamic schemas efficiently.

What to Have for this position

• 7+ years as a Full Stack Developer
• 3+ years in Backend web development in Node.Js
• 5+ years with React +Redux frontend web applications.
• 2+ years leading design and delivery
• Deep Knowledge and experience with JavaScript, TypeScript
• Experience with Databases - MongoDB
• Deep knowledge of software architecture design and REST API
• Experience owning your code quality by writing tests, automation, and monitoring dashboards
• Strong object-oriented design and development capabilities
• B.Sc. degree in Computer Science or equivalent practical experience
• Experience in SaaS or multi-tenant or cloud-based environments or scalable platforms (born in cloud or cloud native companies) - Must
• Experience in working in a foundation/platform team - Advantage
• Experience designing and implementing drag-and-drop builders (e.g., visual editors, form builders, workflow designers) - Advantage

• Experience building end-to-end low-code / no-code platforms, including visual modeling, rule engines, and runtime execution layers - Advantage
