Hello! My name is Henry Hadi Abra

Building Modern Web & Blockchain Solutions with ASP.NET Core
I’m a software developer specializing in ASP.NET Core, with hands-on experience in Web3, smart contract interaction, and blockchain integrations. I help businesses and innovators turn complex ideas into fast, secure, and scalable applications.


I’m a passionate programmer with experience in back-end development, blockchain projects, and consulting. Over the years, I’ve helped startups and established companies turn ideas into production-ready solutions. My expertise spans ASP.NET Core, C#, smart contract integration, and full-stack systems that connect traditional applications with modern Web3 technologies.

Beyond blockchain, I have worked extensively in the crypto and finance markets—building tools such as charting systems, technical indicators, live trading bots, and even NFT scripts. On the creative side, I enjoy backend development for games built with Godot, GameMaker, and other engines, ensuring scalable multiplayer logic and smooth server-side experiences.

When I’m not coding, I enjoy exploring new technologies, refining my skills, and sharing insights with the community. Whether it’s programming, blockchain innovation, or game backend design, I bring curiosity, precision, and adaptability to every project I take on.

How can I help

Need a hand with programming, blockchain, or game development? Reach out and let’s create something great together.

Programming

I specialize in building robust backend systems using C#, ASP.NET Core, and scalable architectures. From REST APIs to real-time WebSocket applications, I design solutions that are efficient, maintainable, and ready for production. My experience spans finance, trading platforms, and enterprise-grade applications.

Blockchain

With deep expertise in Web3 integration and smart contract development, I create systems that connect traditional backends with blockchain networks. I have worked with EVM chains, Solana, TRON, and BSC, delivering projects such as DeFi platforms, NFT collections, token standards, and on-chain analytics.

Consulting

I provide guidance on system architecture, performance optimization, and project planning. Using Domain-Driven Design (DDD) and Clean Architecture principles, I help startups and companies structure their projects for long-term growth, scalability, and maintainability.
