AbyanSiregar
Muhammad Abyan Ridhan Siregar. Data analyst and builder. I collect the numbers, check where they came from, and ship the tools that put them in front of people.
Manifesto
I'm Abyan, a computer engineer who turns raw data into decisions people can trust.
Photo 21:9 — coming soon
Every number keeps its source and its timestamp. And I want to understand the whole system behind it: the pipelines, the servers and the networks.

03 · Document converter
Convertion
KonversiKu converts PDF to Word, Office files to PDF, images to and from PDF, merges PDFs and runs OCR in Indonesian and English, up to 95 MB. Uploads go into an async job queue so long OCR jobs survive proxy timeouts, files are validated by their contents, and results delete themselves after 15 minutes.
