About
Built for the long game.
Modulus Technologies is a focused software company. Small by design. Senior by standard. We take on the complex problems other teams avoid.

Ashwin van der Merwe
Ashwin is a senior software engineer with years of experience building backend systems for enterprise clients. His work spans API design, identity management, cloud infrastructure, and developer tooling.
Currently, Ashwin leads backend API development for Cell C's mobile application — one of South Africa's largest telcos — subcontracting through Teraflow AI. It's the kind of high-stakes, high-scale work that Modulus was built around.
Modulus Technologies is his vehicle for building a small, elite team: developers who take ownership, think beyond the ticket, and deliver software that actually works in production.

How We Work
Principles we don't negotiate on
Performance by default
We don't add performance as an afterthought. It's baked into architecture decisions from the start.
Security first
Authentication, authorisation, and data handling are treated as core concerns, not features.
Clean, maintainable code
Code that the next developer can read and extend. No clever hacks that create long-term pain.
Honest collaboration
We tell you when something is the wrong approach. Our job is to help your business, not just complete a ticket.
