About Hasnain
Hasnain Nisar is an automation engineer at Nisar Automates, where he designs and operates the file-conversion infrastructure behind Convert Fleet. His day-to-day is the unglamorous reality behind the guides on this blog: keeping FFmpeg transcoding pipelines stable under load, hardening REST conversion APIs, and wiring document and media workflows into n8n so they run unattended at scale.
He writes about what he actually ships. Every tutorial here — from PDF/A archiving and bulk image conversion to serverless FFmpeg and webhook-driven automation — comes out of a production system he maintains, with the failure modes, cost trade-offs, and edge cases left in rather than sanded off. The goal is for another engineer to be able to copy the approach and have it work the first time.
Experience
- Operates the production file-conversion API and FFmpeg pipelines that power Convert Fleet.
- Builds unattended document and media workflows in self-hosted n8n for high-volume jobs.
- Specializes in PDF/A archiving, bulk image conversion, and cloud/serverless conversion at scale.
