You will get scalable Node.js backend API SaaS system with clean architecture
Rising Talent
Project details
I build scalable backend systems and APIs using Node.js for SaaS platforms, web applications, and business automation. My focus is on backend architecture, clean API design, and reliable integrations with services like Stripe, OpenAI, CRMs, and third-party platforms.
As a backend developer, I design systems that handle real-world workflows: authentication, payments, background jobs, queues, and data processing. I work with NestJS, Express, PostgreSQL, MongoDB, Redis, and event-driven logic to ensure performance and stability.
This service is ideal if you need a backend developer who can build production-ready systems, not just prototypes. I create APIs, dashboards, and integrations that scale, handle edge cases, and work reliably under load. You get clean code, structured architecture, and a system ready for growth.
will build a scalable backend system for your web application using Node.js, NestJS, and modern API architecture.
As a Backend Developer and Node.js Developer, I specialize in building REST APIs, backend services, and SaaS platforms that are reliable and production-ready.

About Andrii
Backend Developer
Kyiv, Ukraine - 4:24 pm local time
I’m a Full Stack Developer, Backend Developer, and SaaS Developer focused on building scalable, production-ready systems using Node.js, React, and modern API-driven architectures. My work sits at the intersection of Full Stack Developer, Backend Developer, and React Developer roles, with a strong backend-first mindset and real experience delivering systems that run reliably in production.
As a Full Stack Developer, I build systems end-to-end, combining robust backend architecture with clean React-based frontend applications. I work as a Full Stack Developer who can replace multiple roles by owning both frontend and backend, ensuring consistency and performance across the entire system. This Full Stack Developer approach allows me to deliver faster and with fewer integration issues.
As a Backend Developer, I design and implement APIs, services, and data models using Node.js and NestJS. My Backend Developer experience includes building scalable systems with CRON jobs, queues (Bull), and background processing. As a Backend Developer, I focus on performance, stability, and clean architecture that supports long-term growth. This Backend Developer approach ensures reliable systems in real production environments.
As a SaaS Developer, I’ve built platforms like Shopify business management systems with international delivery logic and automation workflows. My SaaS Developer experience includes dashboards, multi-role systems, and internal tools where permissions, workflows, and data integrity are critical. As a SaaS Developer, I always think in terms of scalability and real-world usage, not prototypes.
As a React Developer, I build modern, responsive interfaces using React and Next.js. I work as a React Developer who understands backend constraints, which allows me to create efficient frontend architecture. This makes me not just a React Developer, but a Full Stack Developer and Backend Developer who ensures smooth integration between UI and backend.
As a Node.js Developer, I build backend services, APIs, and integrations that power SaaS platforms and web applications. My Node.js Developer experience includes working with NestJS, Express, CRON jobs, and async workflows. As a Node.js Developer, I focus on writing clean, maintainable code that performs reliably under load, combining both Backend Developer and Full Stack Developer best practices.
As a Full Stack Developer and Backend Developer, I ensure seamless integration between frontend (React) and backend (Node.js). This Full Stack Developer and Backend Developer approach allows me to deliver complete systems, including dashboards, APIs, and integrations with third-party services like OpenAI and CMS platforms such as Strapi.
A significant part of my work as a Backend Developer and SaaS Developer involves:
- API integrations and third-party services
- automation workflows (CRON, queues, background jobs)
- database design and management (MongoDB, PostgreSQL)
- scalable backend systems using Node.js
- SaaS dashboards and internal tools
As a Full Stack Developer and Backend Developer, I’ve worked on:
- Shopify business automation platforms
- AI-powered Telegram bots using OpenAI API
- CMS-based systems with Strapi and automated email workflows
- production-ready SaaS platforms with real users and workflows
My core stack as a Full Stack Developer / Backend Developer / Node.js Developer includes:
- Node.js NestJS Express
- React Next.js
- MongoDB PostgreSQL MySQL Redis
- REST APIs GraphQL
- Docker Git
Clients typically work with me when they need:
- a Full Stack Developer who owns frontend and backend
- a Backend Developer who understands production systems
- a Node.js Developer for scalable backend architecture
- a React Developer who can integrate with real APIs
- a SaaS Developer who builds systems for long-term use
As a Full Stack Developer, I focus on delivering systems that are not just functional, but maintainable and scalable. As a Backend Developer, I ensure reliability and performance. As a SaaS Developer, I design systems that support real business workflows. As a React Developer and Node.js Developer, I build clean, efficient, and production-ready applications.
Long-term results come from strong architecture and clear system design, and that’s exactly what I deliver as a Full Stack Developer, Backend Developer, SaaS Developer, React Developer, and Node.js Developer.
