About JSfinity
Est. 2020
We build software
that matters.
JSfinity is a software development agency founded in 2020. We exist to give ambitious founders and growing businesses access to the kind of engineering talent and product thinking that was previously reserved for funded startups with full-time teams.
"Software should be a competitive advantage, not a liability."
— Our founding principleToo many businesses are held back by bad software — slow, expensive, and built without care. We started JSfinity to fix that. We bring the craft, process, and accountability of a world-class engineering team to every project, regardless of its scale.
We intentionally stay small. That means we work with a limited number of clients at a time — so every project gets our full attention, not a slice of it.
It's just the two of us — design and engineering, working closely together from day one. No middlemen, no handoffs. We don't outsource. We don't disappear after launch. We build things that last.
What We Believe
Values we actually live by.
Craft over speed
We move fast — but never at the expense of quality. Good code is an asset. Bad code is debt. We write the kind of codebase you're proud to hand to the next engineer.
Transparency always
No hidden timelines. No surprise invoices. No vague status updates. We communicate like the professionals we are and treat your business like our own.
Outcomes, not hours
We're not billing-padders. We're focused on the result your business needs, and we structure our work to achieve it as efficiently as possible.
Long-term partnership
The best work happens in ongoing relationships. We get to know your business deeply over time and the quality of what we build compounds as a result.
