Rising Talent
Project details
You will get a secure and scalable backend API built with Node.js, REST API architecture, and PostgreSQL or modern backend frameworks like NestJS. I develop backend systems that handle business logic, database operations, authentication, and third-party integrations with clean architecture and production-ready code. Whether you need a custom API, a backend for your SaaS product, or a scalable server-side system, I deliver reliable backend development focused on performance, security, and maintainability. Current Upwork backend listings that rank well consistently emphasize Node.js, REST API, PostgreSQL, NestJS, and secure/scalable backend development in exactly this style.
What sets my project apart:
• Secure backend API tailored to your product needs
• Node.js, REST API, PostgreSQL, and NestJS expertise
• Clean, scalable architecture for real-world production use
• Source code with structured delivery and communication
This project is ideal for SaaS products, web apps, dashboards, internal tools, and custom backend systems.

✅ End-to-end ownership from MVP to production
✅ Product mindset focused on business value & long-term growth
✅ Clear communication and structured delivery
I’m a Full-Stack Developer focused on building scalable, production-ready web applications that deliver real business value. I work at the intersection of modern web development, AI agents & LLM integrations,, helping SaaS teams and startups turn ideas into reliable, high-performance AI-powered products using React, Next.js, Node.js, Python, LangChain, RAG pipelines, vector databases (Pinecone / Weaviate), OpenAI & LLM integrations, AI agents, and modern cloud infrastructure.
My strength lies in designing clean, maintainable systems with a strong foundation in architecture, performance optimization, and structured delivery. I approach projects with a product mindset—thinking beyond code to long-term scalability, usability, and ROI.
What I work on:
✔ End-to-end full-stack AI-powered web application development for SaaS & startups
✔ Scalable backend systems and modern frontend interfaces with React & Next.js
✔AI-powered features, AI agents, intelligent workflows, LangChain, RAG pipelines
✔Computer vision applications for detection, classification, and automation
✔Interactive and immersive web experiences with Three.js / React Three Fiber
Core technologies:
Frontend: React.js, Next.js,Three.js Tailwind CSS, JavaScript/TypeScript
Backend: Node.js, Fastify, Python, PostgreSQL
DevOps: Docker, CI/CD, cloud deployment
AI: Modern frameworks such as LangChain, OpenAI API integrations
Computer Vision :OpenCV, vision models, image processing pipelines
Other: Three.js / React Three Fiber for 3D/interactive UIs
I’ve contributed to production systems, including a security-focused open-source application where I improved PWA functionality and implemented intelligent detection logic to enhance reliability and accuracy.
If you’re looking for a developer who communicates clearly, works with structure, takes ownership of outcomes—not just tasks—and can deliver scalable SaaS, AI-integrated, or Web3-enabled solutions, I’m open to discussing how I can support your project.
