You will get a Node.js or NestJS REST API built and documented
Project details
Need a backend that's actually built to last — not a fragile prototype? I build clean, documented Node.js / NestJS APIs with proper structure, auth, and validation.
What you get:
• Well-structured REST or GraphQL endpoints in NestJS/Node.js + TypeScript
• Database design (PostgreSQL or MongoDB) with sensible models and migrations
• Secure auth — JWT, role-based access control, ready for SSO if you need it
• Input validation, error handling, and Swagger/OpenAPI documentation
• (Premium) background jobs/queues, third-party integrations, Docker, and a handover
Background: 5+ years building backends serving 1M+ users — search infrastructure, event-driven systems, payments, and integrations.
Message me your requirements (or a rough spec) and I'll confirm scope + timeline.
Done = working, documented API you can run and extend.

About Laiba
Senior Backend Engineer | Node.js, NestJS, APIs | n8n & AI Agents
Islamabad, Pakistan - 1:10 am local time
business running while you sleep.
Senior backend engineer (5+ years) specializing in NestJS/Node.js microservices,
clean REST & GraphQL APIs, and event-driven systems. My last platform served 1M+
monthly users across 3 verticals (32M+ pageviews, 530M+ impressions) on
Elasticsearch search I built from scratch, Azure Service Bus pipelines, and a
dual-gateway payment system.
WHERE I'M DIFFERENT ON AUTOMATION
Most n8n / Make builders hit a wall the moment a workflow needs real code. I'm a
backend engineer first — so I build n8n and AI-agent automations with custom code
nodes, real API integrations, webhooks, error handling and retries. The result is
automation that survives real data and real traffic, not a demo that breaks next week.
WHAT I BUILD FOR YOU
- Scalable backends & APIs — NestJS, Node.js, TypeScript, REST/GraphQL
- n8n & AI-agent automation — custom nodes, OpenAI/Claude, webhooks, monitoring
- Search & analytics infrastructure — Elasticsearch, MongoDB aggregation pipelines
- Event-driven systems — Azure Service Bus, queues, retry-safe consumers
- Payment & third-party integrations — gateways, ERPs, webhooks, reconciliation
- Secure auth — OpenFGA fine-grained authorization, RBAC, SAML SSO, JWT/OAuth2
SELECTED WORK
- Marketplace backend (NestJS NX monorepo): 3 verticals, 1M+ users, Elasticsearch
search + geo-scoring, event-driven sync, full payment lifecycle.
- HIPAA-grade healthcare platform (.NET/ABP): OpenFGA authorization, SSO, real-time
messaging across 10+ modules, Azure Cosmos DB.
- E-commerce backend (NestJS/GraphQL): Shopify Storefront + LMS integration,
analytics pipeline.
