I'm Alexander Christian — a fullstack developer and Computer Science student shipping decentralized applications on Base and Lisk, and AI tools for Indonesian markets.
Hi, I'm Alex.
Computer Science student at BINUS University shipping fullstack on-chain applications across L2 ecosystems including Base and Lisk. I'm proficient in Solidity, Foundry, and modern web frameworks, and I'm currently expanding into AI/ML with practical applications for Indonesian market intelligence.
When I'm not shipping smart contracts, I'm mentoring 200+ students at BINUS as a lab assistant across Scientific Computing, Big Data, and Cloud Infrastructure courses, because teaching is still the sharpest way to learn.
Tools I reach for.
A working toolbox across the on-chain stack, modern web, and systems — picked for what ships, not what trends.
Blockchain
Languages
Web & Desktop
Data & DevOps
Projects & experiments.
Hackathon deliverables, on-chain demos, and side projects. Most built under competitive deadlines.
On-Chain Freelancing Platform
Fullstack decentralized freelancing platform built on Base L2 with on-chain reputation scoring. Integrated IDRX stablecoin for IDR-denominated payments and Ponder for real-time blockchain event indexing.
On-Chain GameFi
Growtopia-inspired blockchain game with on-chain asset ownership and game mechanics powered by smart contracts on Lisk. Built the Web3 integration layer connecting Unity gameplay to on-chain state.
Hyperlocal AI Market Chatbot
AI-powered chatbot helping Indonesian SMEs (UMKMs) simulate local market conditions and gain actionable business insights. Built as a working demo for the ideathon competition.
Let's build something good.
Open to collaborations, hackathon teams, and internship opportunities in blockchain, AI, or fullstack engineering.
