How we build

Built with AI. Checked by engineers.

We use AI tools across design, coding and testing, so you get working software sooner and at lower cost, without giving up quality or control.

AI speeds up the buildScaffolding, boilerplate, test cases and documentation are drafted in hours, not days.

Senior engineers review every lineNothing reaches production without a human code review and automated tests.

You own all of the codeYour data stays private, and the source code and documentation are handed over to you.

Approach

Four stages, no surprises.

Every engagement follows the same path, whether it is a six-week portal or a multi-year platform. You see working software early and often.

Discover

We map the process, the systems it touches and what success looks like, then agree scope, timeline and price.

Design

Data model, integrations and key screens are designed and signed off before the build starts.

Build

Short sprints with a working release at the end of each one, on a staging site your team can use.

Launch & support

Go-live, data migration and training, followed by ongoing support and improvements.

Technology

Proven tools, chosen for the long run.

Mature, well-supported technology your future team can maintain, connected to whatever you already run.

About Avenstra

A software company that builds and stays.

Avenstra Software is a Sri Lankan engineering company building enterprise systems for clients in Sri Lanka, the UAE and beyond.

We started in travel technology, one of the most integration-heavy industries there is. That discipline now shapes everything we build: ERPs, HR and incentive systems, data platforms, customer portals and AI assistants that work on top of them.

Clients keep working with us long after launch, because the people who designed the system are the ones who support it.
