I build things, connect the dots, and automate the boring bits.
Jakarta-based engineer who went from studying galaxies to building the systems behind everyday deliveries. Turns out, both involve a lot of data and figuring out why things moved somewhere unexpected. 🔭📦
These days, I lead platform and AI engineering in express logistics, working with teams across backend, frontend, mobile, QA, and data. My work has also taken me through oil & gas, faith-based digital products, and university infrastructure.
Still happiest when I can turn a messy problem into a useful tool—and save someone a few hundred clicks along the way.
- Making shipping code easier: Go and React/Vite templates, developer tools, and AI-assisted workflows. Yes, I work in shipping and help people ship.
- Keeping the backend moving: microservices, pricing engines, Kafka integrations, and file services.
- Giving data somewhere useful to go: lakehouse pipelines, conversational analytics, MCP tools, and automation.
- Helping teams build together: technical direction, mentoring, and fewer hoops between an idea and a working feature.
| Project | The idea | Built with |
|---|---|---|
| Coretax Renamer | Give tax invoice PDFs sensible names. Your browser does the paperwork, offline too. | JavaScript, pdf.js, PWA |
| Islamic Companion | Prayer times, fasting schedules, Quran search, and Zakat thresholds from the terminal. | Shell, Python |
| Go Clean Architecture PoC | An experiment in giving business logic some breathing room from HTTP and databases. | Go, Fiber |
| DNN Redshift Research | My astronomy thesis: teaching neural networks to estimate redshifts from galaxy images. | Deep learning, astronomy |

Some of my biggest projects live behind a login. A few highlights:
- Logistics: built a Go pricing engine that cut database storage needs by 90%.
- Business operations: simplified a vendor invoicing pipeline connected to SAP, cutting processing time by 90%.
- Faith-based digital products: put CI/CD in place and cut deployment time by 95%.
- Data infrastructure: led the move of Bronze-layer ingestion from Snowflake compute to Apache Iceberg on AWS S3 Tables, with Kafka Connect and Airflow doing the moving.

A peek at my public GitHub activity. Plenty of the day-job code lives elsewhere. Language charts count code, not coffee-fueled expertise. ☕
I studied Astronomy at Institut Teknologi Bandung, where I explored deep learning for photometric redshift estimation. These days the datasets are a little closer to Earth, but I still like asking questions, testing assumptions, and seeing what the data has to say.
When something finally clicks, I like passing it on: Python teaching materials, GraphQL demos, and the occasional blog post.
Building something around developer platforms, practical AI, or data? Say hello—I'm always up for a good engineering conversation.
