I'm Dinakaran Prabalanathan, accelerating developer velocity through innovative test engineering.
I help engineering teams ship high-quality software through Python automation frameworks, developer tools, and AI-powered diagnostics.
I build robust test frameworks using Python, Playwright, PyTest, and Selenium — managing 200+ automated test suites per build cycle.
I engineer tools that eliminate bottlenecks — from 24/7 rerun engines to AI-powered MCP toolkits with 178 tools inside the IDE.
I develop solutions that save hundreds of hours monthly — recognized with Amazon's Innovation Awards for creative engineering.
I am a Software Engineer II in Test (SE2) with over 5 years of professional experience specializing in Python-based automation frameworks, developer tools, and comprehensive test support.
My expertise spans Python, PyTest, Playwright, Selenium, REST APIs, and Agentic AI tooling, with a focus on building engineering tools that eliminate release bottlenecks and optimize developer velocity. I've been recognized with Innovation Awards at Amazon for developing innovative testing solutions.
I collaborate closely with developers and project leads to establish testing requirements, review code, debug intricate system failures, and build solutions including an AI-powered MCP toolkit with 178 tools that reduced analysis cycles from 30-50 minutes to 3-5 minutes.
My professional journey
