Profile

Who Is Dhruba Singha Roy?

Dhruba Singha Roy is a QA and automation engineer at Cognizant and the founder of Randomly.online, a free ecosystem of 400+ browser-based tools that process files locally. He builds test automation with Playwright, Selenium, Java and CI/CD pipelines, and previously founded the Animetype social app and led a Google Developer Student Club of over 1,000 members.

Foundation & Animetype Phase 1 (2022-2023)

My journey began deep in college life at the Haldia Institute of Technology. Driven by a desire to build living, interactive systems, I poured my early focus into mobile development. I single-handedly built and launched Animetype, a dedicated social media platform, and successfully published it on the Google Play Store. Seeing it scale and acquire thousands of users was my first real-world exposure to system architecture and product development.

Community Leadership Phase 2 (2023-2024)

With a solid technical foundation, I stepped up as the Google Developer Student Clubs (GDSC) Lead. My focus shifted from purely writing code to scaling human networks. I successfully grew our community to over 1000 members and personally mentored more than 100 students, elevating our chapter to Tier-1 status. This phase taught me that true architecture isn't just about databases; it's about leading teams and communicating a unified vision.

The Web Ecosystem Phase 3 (2025)

Driven by a desire to build accessible utility at scale, I pivoted heavily into advanced web development and founded Randomly.online. I engineered it from the ground up into a massive, worldwide ecosystem featuring over 400+ distinct tools and a dedicated Chrome extension. This heavy investment in web technologies honed my skills in UI/UX, frontend architecture, and deploying high-traffic systems.

Enterprise QA & Automation Phase 4 (2026-Present)

Today, I am navigating my profession as a QA / Automation Engineer at Cognizant. My enterprise journey began with a 4-month internship in Tambaram, Chennai (2024), where I gained intensive hands-on experience with Java, OOPs, DSA, Selenium, TestNG, API Testing, SQL, Git, Jenkins, GitHub Actions, CI/CD, and overall test strategy. This rigorous foundation led to a full-time role by August 2025. After initially mastering manual testing, I rapidly scaled into full automation architecture. I now design and maintain robust test frameworks utilizing Playwright, Selenium, Docker, and advanced CI/CD pipelines—ensuring that massive enterprise systems don't just work, but scale flawlessly.

Frequently Asked Questions

Who is Dhruba Singha Roy?

Dhruba Singha Roy is a QA and automation engineer at Cognizant and the founder of Randomly.online, a suite of more than 400 free browser-based tools. He graduated from Haldia Institute of Technology, built and published the Animetype social app on Google Play, and led a Google Developer Student Club of over 1,000 members before moving into enterprise testing.

What does Dhruba Singha Roy do at Cognizant?

He works as a QA and automation engineer, designing and maintaining the test frameworks that cover large enterprise systems. Day to day that means automated regression suites, API testing, and the CI/CD pipelines that run them. He joined as an intern in Tambaram, Chennai in 2024, moved into a full-time role in August 2025, and progressed from manual testing into full automation architecture.

Which test automation tools does he work with?

His core automation stack is Playwright and Selenium, driven from Java with TestNG for test orchestration. He uses REST API testing and SQL for data validation, Docker to containerize test environments, and Jenkins and GitHub Actions to run suites continuously. Git underpins version control and code review across every framework he maintains.

What technologies does he specialize in for enterprise development?

His primary expertise is the Java ecosystem for backend systems and microservices, including Spring Boot, SQL database management, and the system design patterns that scalable enterprise applications require. He also has significant Android native experience in Kotlin, which lets him bridge backend logic and mobile frontend user experience. His time at Cognizant has refined these skills in a real-world agile environment.

What is Randomly.online?

Randomly.online is the free tool ecosystem he founded in 2025. It offers over 400 utilities across PDF tools, image tools, calculators and text tools, plus a Chrome extension. Every tool runs entirely in the browser, so files are processed locally with JavaScript and are never uploaded to a server.

What is Animetype?

Animetype is a social media platform for anime fans that he built single-handedly and published on the Google Play Store while studying at Haldia Institute of Technology. It scaled to thousands of users and was his first real exposure to system architecture and product development, which shaped the way he approaches building software today.

What does he mean by “living systems”?

A living system is software that reacts, evolves and gives feedback rather than sitting static. On this portfolio that shows up as micro-interactions: cards lifting as the cursor approaches, background particles responding to movement, navigation that behaves like a terminal. In professional work it means real-time data sync, responsive layouts, and proactive error handling that feels organic rather than robotic.

How does he approach team leadership and project management?

Leadership is a skill he built as a Google Developer Student Clubs lead, where managing 1,000+ members demanded empathy, clear communication and strategic planning as much as technical knowledge. He breaks complex problems into manageable tasks, delegates against individual strengths, and keeps a constant feedback loop so the work stays aligned with the final vision. Git keeps collaboration clean and conflict-free.

Where did Dhruba Singha Roy study?

He studied at Haldia Institute of Technology in West Bengal, India. His time there covered the foundations he still relies on, including Java, object-oriented programming, data structures and algorithms. It was also where he built and launched Animetype and later served as the institute's Google Developer Student Clubs lead.

Was Dhruba Singha Roy a Google Developer Student Clubs lead?

Yes. He served as the founding Google Developer Student Clubs lead at Haldia Institute of Technology from 2023 to 2024. He grew the chapter past 1,000 members, personally mentored more than 100 students, and helped it reach Tier-1 status. That phase shifted his focus from writing code alone to scaling teams and communities.
