Quality engineer at heart. Builder by habit.
I'm a Lead Software Engineer at GovTech Singapore, where I lead test automation, performance testing and quality governance for TradeNet — the National Single Window that processes import, export and transhipment declarations for Singapore's entire trade community.
My work sits where quality meets engineering: I design automation frameworks from the ground up, prove systems hold up under load with performance testing, govern quality with clear standards and release gates, and coach teams to treat quality as everyone's job. I build with AI every day — using tools like Claude, GitHub Copilot and Cursor to move faster without lowering the bar. Along the way I've published a family of open-source testing tools used by engineers worldwide and ranked #1 on Test Automation University.
- Framework architectUI, API, mobile and visual testing frameworks that scale with the product and stay readable for the whole team.

What leads and colleagues say
"He is a huge asset to any team."
I rarely come across real talents who stand out like Osanda. He is exceptionally smart, honest, hardworking, friendly and very easy to work with, and his attention to detail is impressive. Osanda has well-grounded experience in designing high-ROI test automation frameworks — from API to web and mobile. His exceptional automation skills, combined with his passion for innovation, made a dramatic impact on the organisation. He is results-driven and completed his assignments on time, often ahead of schedule, and he is well respected and highly regarded by all stakeholders. I highly recommend Osanda — he is a huge asset to any team.
"An exceptional automation engineer."
It was fantastic to work with Osanda — an exceptional automation engineer who is broad-minded and has exceptional knowledge of the test automation arena. He developed a test automation framework called IntelliAPI, which the Pearson Mobile team uses to automate API tests. He also introduced a mobile automation framework using Gauge and Appium to automate Android and iOS tests, and a web automation framework using Gauge and Selenium that can automate any browser on any platform. In parallel, he contributed to the Gauge framework developed by ThoughtWorks, and he is an active blogger whose technical articles are a great reference for anyone learning automation testing. He handles pressure well, is hardworking and self-motivated, and can mentor and coach other team members. I am sure he is an exceptional asset to any team.
"A unique team player and an asset to the team."
Osanda is a very enthusiastic, creative and innovative person who never limits himself to what his job role requires. I met him at Mitra Innovation, where he was an Associate Quality Assurance Engineer on the same project I worked on as a business analyst. He is keen to gain new knowledge every day and apply it to practical scenarios — his performance and innovations amazed us daily. He never hesitated to help a team member, share what he had learned or work towards the end goal. That is what made him a unique team player and an asset to the team.
"A highly skilled Java-based automation engineer."
Osanda is a highly skilled Java-based automation engineer, with automation framework development skills covering UI, API and mobile automation. I highly recommend him for an automation engineering position.
"Osanda could be called a 'maestro' of our time."
Automation is no longer a buzzword — it's a strategic priority that defines an organisation's success. As far as automation training is concerned, Osanda Nimalarathna could be called a 'maestro' of our time. Highly technical, competent and knowledgeable, his teaching skill is unmatched. His sessions were extremely informative and interactive, focusing not only on theory but primarily on practice — applying automation and its advanced methods in the ever-evolving discipline of software engineering. On a personal note, Osanda is a kind and gentle individual, always willing to contribute to the well-being of others. I see him as a great leader.
