You will get NestJS or Node.js REST API development, built or fixed
Project details
A backend that works under load — and that your team can actually maintain.
I'm a backend engineer with 7 years building REST APIs and microservices in NestJS, Node.js, and Laravel. I've optimized APIs to handle 10,000+ concurrent requests and cut response times by 35%. Whether you need a bug fixed, a new module, or a full API built right, I deliver clean, tested, documented code.
What you get:
Working REST API in NestJS / Node.js, tested and documented
Proper validation, auth, and error handling
Database integration done right (PostgreSQL, MongoDB, Redis)
Code your team can read and extend
Why me: My GitHub is public — you can inspect my real code before ordering. Most sellers can't show you that.
How I work: Clear written communication, precise scope, no surprises. Message me your requirements and I'll confirm the right tier before you order.

+$15About Eduardo
Backend Engineer NestJS Node.js Python | REST APIs AI Integrat
Merida, Venezuela - 10:43 pm local time
I build scalable REST APIs, microservices, and backend systems with NestJS, Node.js, and Python (FastAPI). Recent results for FinTech and enterprise clients: 35% faster API response times, 10,000+ concurrent requests with no degradation, and 99.5% uptime.
What makes me different: I bring AI to production, not demos. I build RAG pipelines with retrieval evaluation, hallucination control, and per-query cost tracking using Python + the OpenAI API with public, documented GitHub repos you can review before hiring me.
How I work with you:
Clear written communication (I'm fully fluent in written English; I keep calls short and focused)
I ask the right questions upfront, then deliver without hand-holding
Clean, tested code — Jest, PHPUnit, TDD
What I can help you with:
Build or scale REST / GraphQL APIs (NestJS, Node.js, Laravel)
Backend architecture, microservices, event-driven systems
AI integration: RAG pipelines, LLM agents, tool-calling, cost control
AWS deployment + CI/CD (ECS, Lambda, GitHub Actions)
Performance: query optimization, Redis caching, latency reduction

Steps for completing your project
After purchasing the project, send requirements so Eduardo can start the project.
Delivery time starts when Eduardo receives requirements from you.
Eduardo works on your project following the steps below.
Revisions may occur after the delivery date.
Understand your requirements
We confirm exactly what you need the scope, your stack, and the expected result so we're aligned before I write any code.
Build or fix the API
I write clean, tested code in NestJS/Node.js with proper validation, error handling, and database integration where needed.
