File-sharing SaaS · Case study
ufile.io: file-sharing at scale, refined and optimised.
- 544M+ files downloaded
- 1.5M+ registered users
- Acquired for a seven-figure sum (USD)
The challenge
Where they started.
ufile.io is a free file-sharing platform in a brutally demanding category: millions of people expect instant, no-signup uploads of large files and downloads that never fail - while the business quietly carries the cost of moving and storing huge volumes of data. Keeping a platform like that fast, reliable and cheap to run as it scales is constant, detailed engineering.
Business goals
What success looked like.
- Ship new features users actually wanted
- Make uploads and downloads faster and more reliable
- Optimise performance and infrastructure cost at scale
- Improve the platform without disrupting millions of active users
The solution
What we built.
ufile.io came to us through the same client behind Shoprocket - they trusted us with a second product. Across 2021 and 2022 we developed new features and focused on the enhancements and optimisations that keep a high-volume file host fast for users and efficient to run.
- New features built and shipped into the live platform
- Upload and download paths optimised for speed on large files
- Performance work to keep the experience snappy under heavy load
- Infrastructure and storage optimisations to control cost at scale
- Improvements rolled out safely to a platform already serving millions
Under the hood
How we built it to last.
A file host at this scale lives or dies on how efficiently it moves and stores data. Our work focused on the parts users feel - faster, more reliable uploads and downloads, even on large files - and the parts they don't: performance and storage optimisations that keep a high-volume platform cheap enough to run. On a product serving millions, small efficiencies compound fast.
How we worked
A transparent build.
We joined an established platform and worked in tight, careful cycles - shipping features and rolling out optimisations without disrupting a service millions of people were already using.
The results
What changed.
Years on, ufile.io is still running successfully:
- 544M+ files downloaded to date
- 12.9M+ files uploaded
- 1.5M+ registered users worldwide
- Later acquired outright for a seven-figure sum (USD)
Years on, ufile.io is still going strong - hundreds of millions of downloads and counting - and the platform was acquired for a seven-figure sum. We were glad to play a part in keeping it fast and efficient at that scale.
“I've had the pleasure of working with Indesh for several years across multiple projects, and I can confidently say he's one of the best developers I've worked with. His technical skills are exceptional, particularly in Laravel, APIs, SaaS platforms, and scalable backend systems. He consistently delivers high-quality work, communicates clearly, and always approaches challenges with professionalism and attention to detail. Beyond his technical ability, Indesh is reliable, trustworthy, responsive, and genuinely enjoyable to work with. I would recommend him without hesitation to anyone looking for a highly skilled and dependable developer.”
What we took from it
Lessons learned.
ufile.io was a reminder that on a high-volume product, optimisation is a feature in itself. Shaving cost and latency off millions of transfers isn't glamorous, but it's exactly what keeps a platform fast, profitable and worth acquiring.
