Meet the Minds Behind quarionelva
Our team brings together decades of experience in financial technology, data science, and user experience design. We're not just building tools—we're crafting solutions that genuinely make financial management more accessible for Australian businesses and individuals.
Leadership & Expertise
Our leadership team combines technical innovation with deep understanding of Australia's financial landscape. Each brings unique perspectives shaped by years of working with businesses across different sectors.

Callista Rodriguez
Chief Technology Officer
Callista spent eight years at major Australian banks before joining quarionelva in early 2023. Her background in systems architecture and regulatory compliance helps us navigate the complex requirements of financial software. She's particularly passionate about making powerful tools accessible to smaller businesses that traditionally couldn't afford enterprise-level solutions.

Brennan Walsh
Head of Financial Innovation
Before quarionelva, Brennan worked with over 200 small businesses across Newcastle and Sydney, helping them streamline their financial processes. He joined us in mid-2024 because he believed technology could solve many of the recurring problems he saw. His hands-on experience with diverse business models helps shape our product development priorities.
Our Mission
We believe financial technology should solve real problems, not create new complexities. Too many businesses struggle with disconnected systems, unclear reporting, and tools that don't speak to each other.
quarionelva exists to bridge these gaps. We're building a platform where data flows naturally, insights emerge clearly, and business owners can focus on what they do best instead of wrestling with their financial tools.
What Drives Us
- Practical Solutions: We test everything with real businesses before release. If it doesn't solve a genuine problem, we don't ship it.
- Australian Focus: Our tools understand GST, BAS reporting, and the specific challenges of operating in the Australian market.
- Transparent Communication: We explain what our tools do and don't do. No hidden fees, no oversold promises.
- Continuous Learning: Financial regulations change, business needs evolve. We stay current and adapt our platform accordingly.
