You will get Build a Scalable REST API with .NET Core, Go, or Node.js
Project details
Need a clean, well-structured backend API for your app, website, or admin panel? I will build a production-ready REST API using either .NET Core or Go (Golang) based on your preference — with features like authentication, role-based access, and robust database design.
I’ve built real-world backend services for major retail ecosystems, including payment aggregators and transaction processing platforms. Your project will follow best practices in API versioning, database modeling, and code structure.

Versatile Developer | Backend, Machine Learning & Blockchain
Sleman, Indonesia - 4:34 pm local time
I'm a software engineer with a strong background in building APIs, full-stack applications, and backend systems at Indomaret Group—one of Indonesia’s largest retail companies. I specialize in backend development using .NET Core and Golang, with hands-on experience designing APIs for real-world systems like payment aggregation services.
On top of that, I'm passionate about cutting-edge technologies like Machine Learning and Web3:
Built and deployed machine learning models for real-time object detection and segmentation
Developed smart contracts and dApps for secure, transparent systems using Solidity, Web3.js, and Ethereum
Whether you're building a traditional backend, a smart contract system, or deploying ML models, I bring clean code practices, system thinking, and a strong delivery mindset.
🧰 Tech Stack: .NET Core, Golang, SQL Server, PostgreSQL, React.js, Python, TensorFlow, Solidity, Web3.js, Docker
Let's bring your idea to life with reliable backend logic, intelligent systems, or decentralized solutions.
