I'm a software engineer who enjoys learning by building — and occasionally breaking things. Most of my work revolves around backend systems, Web3, and DeFi, but I'm always exploring how complex systems actually work in practice.
- 🌱 Digging deeper into smart contracts, on-chain indexing, and DeFi protocol internals
- ✍️ Writing notes, experiments, and lessons learned at afrijal.dev
- 💬 Happy to chat about backend architecture, Web3, or side-project ideas

On GitHub since 2015 — a decade of building, breaking, and learning. Roughly how it went:
| Era | What I was doing |
|---|---|
| 2025 – now | Full-time in Web3 & DeFi: stablecoin infrastructure, on-chain indexers, order matching & settlement engines, and Solidity contracts with Foundry. Thousands of commits a year across backend, frontend, and smart contracts. |
| 2024 | Broadened the toolbox: Astro sites, a Rails API, Docker/Postgres setups, and community projects for WonogiriSpace. |
| 2020 – 2023 | Went deep on the Vue ecosystem — Vue 3, Nuxt, Pinia, Deno, TypeScript. Built my own wedding invitation platform end-to-end (Vue + admin + API) and contributed to privy-open-source/design-system. |
| 2017 – 2019 | Cut my teeth on JavaScript: React Native apps, Express + Sequelize APIs, GraphQL, Angular starters, and small libraries like nominal-bilangan. Co-building with the wonogiridev community. |
