Node.js Backend Developer Needed for API Integration & Backend Fix
Mykyta did a great job with the Node.js backend task. He understood the requirements immediately, handled the API integration and backend fixes without unnecessary back-and-forth, and kept the implementation clean. Communication was easy and everything worked as expected. Would definitely work with him again.

Building a new product
As a Node.js Backend Developer, I can take an idea from technical architecture to production. That includes database design, backend NodeJS development, REST APIs, authentication, payments, third-party integrations, background jobs, cloud infrastructure, and deployment.
I focus on choosing an architecture that fits the actual stage of the business. An MVP doesn't need enterprise complexity on day one — but it should not require a complete rebuild once users arrive.
Scaling an existing Node.js backend
Already have a product in production? I work with existing Node.js applications that need better performance, cleaner architecture, new functionality, or greater scalability.
As a Back End Developer Node.js specialist, I work with PostgreSQL and MongoDB query optimization, Redis caching, queues, WebSockets, API performance, background workers, Node microservices, Docker, AWS, and CI/CD.
The objective is simple: identify the real bottleneck before adding more infrastructure.
Building complete React + Node.js products
For projects that need both sides covered, I work as a Full Stack NodeJS Developer across Node.js, React, Next.js and TypeScript.
My React NodeJS experience includes SaaS dashboards, admin panels, CRM systems, marketplaces, analytics platforms, customer portals, and internal business applications. As a React Node Developer, I can connect frontend requirements directly to backend architecture instead of treating them as separate systems.
AI & business automation
I build AI-powered applications where Node.js acts as the orchestration layer between users, business logic, databases, LLMs, and external services.
This includes OpenAI API integrations, AI workflows, document processing, structured outputs, background processing, CRM automation, internal tools, data pipelines, and third-party API integrations.

As a Node.js Developer with deep backend experience, I build systems around maintainability, performance, security, and business requirements — not technology for technology's sake.
My work as a Node.js Backend Developer spans SaaS, FinTech, Healthcare, AI Services, EdTech, eCommerce, marketplaces, Real Estate, and MarTech. I've worked on payment processing, authentication systems, multi-tenant platforms, real-time applications, API-heavy products, Node microservices, and data automation.
As a Backend NodeJS Developer, I handle Node.js architecture, NestJS and Express.js services, PostgreSQL and MongoDB databases, Redis caching, RESTful API development, WebSockets, background jobs, authentication, integrations, and cloud infrastructure.
As a Full Stack Node.js React Developer, I extend that backend expertise into React, Next.js and TypeScript. This allows me to own the complete technical flow from database and API architecture to the interface your customers actually use.
Whether you need a Node.js Developer, Node.js Backend Developer, Backend NodeJS specialist, Back End Developer Node.js, Full Stack NodeJS Developer, or React Node Developer, the goal is the same:
Build the simplest reliable system that solves the business problem today — without creating a technical problem tomorrow.
