An Australian software engineering company.

Diyonix was founded by Chanaka Jathung Arachchige, a Melbourne-based software engineer who has designed, built and led delivery of business software since 2013.

His career started in Colombo at hSenid Software International, beginning in implementation, working alongside the businesses using the software, before moving into engineering and senior engineering roles. That early time close to real users still shapes how Diyonix works: understand the operation first, then write the code.

In Melbourne he has built web platforms for compliance training and salary packaging, progressing from senior engineer to project lead and technical lead, with hands-on depth across .NET, SQL Server, APIs, React and cloud infrastructure. He holds a Bachelor of Engineering in Software Engineering from London Metropolitan University.

He also builds and runs his own products, including Boothiva, a multi-tenant SaaS platform with Windows kiosk software, and a smart-home energy platform. Owning products from database to deployment is the same end-to-end responsibility Diyonix brings to client work.

Kulani Jayathilaka leads sales, marketing and client relationships at Diyonix. She is usually the first person you'll speak with, and she stays involved throughout, so your priorities stay clear and nothing gets lost between the business and the engineering.

Her background is in consultative sales and customer relationships in technology: at Telstra, where she was also an Apple Champion training sales staff on product knowledge, and in outbound sales and sales operations for a compliance-training software provider.

She co-founded Boxedbliss, a personalised corporate and personal gifting business, so she understands running a small business from the client's side of the table. Before moving to Australia she worked in marketing and CRM roles in Sri Lanka, and she holds a Master of Commerce (Information Technology) from Charles Sturt University.
