Biloliddin Abdurasulov

Software Development Engineer in Test (SDET) with hands-on experience designing, developing, and maintaining scalable test automation frameworks for modern web applications. Experienced in using Cypress, Playwright, JavaScript, and TypeScript to deliver reliable end-to-end, UI, and API test automation solutions that improve software quality and accelerate release cycles.

Currently working at PolicyCON, where I contribute across automation, regression, exploratory, usability, and accessibility testing. I collaborate closely with developers, product managers, and QA engineers to identify defects early, improve testing processes, and support high-quality software delivery within Agile environments.

Passionate about quality engineering, continuous improvement, and building efficient automation frameworks that reduce manual effort and increase release confidence. Strong problem-solving skills, attention to detail, and a commitment to delivering robust, user-focused software solutions.
