About
A short introduction
I am a Computer Engineer graduated from GEC with a strong foundation in software development, test automation, and full-stack web applications. Driven by curiosity and a passion for open-source technologies, cloud computing, and Artificial Intelligence, I love transforming complex ideas into functional, scalable software.
My technical journey includes hands-on experience in both building and breaking software. During my time as an Engineering Intern at OneShield India, I focused on QA and Test Automation, writing robust test cases for enterprise-level software using Selenium and Cucumber. On the development side, I enjoy building responsive cross-platform applications, having developed a full-stack social networking application using the MERN stack and React Native.
Beyond coding, I thrive in fast-paced, collaborative environments. Whether I’m regularly tackling algorithmic challenges in competitive programming contests or leading a team to manage live events as a Coordinator for our technical festival, TECHNIX, I enjoy problem-solving under pressure and driving projects to success.
If you’re interested in contributing in some open-source projects I work on, feel free to get in touch.

Say how many report limitations were omitted (opens in a new tab)
Reports now state how many distinct limitations were omitted after the first 30, in both the Markdown and HTML outputs.
-
Resolve and disclose application graph import facts (opens in a new tab)
The JavaScript application mapper resolves every retained import instead of only the first 2,000, and discloses truncated module facts as a partial-coverage limitation.
-
Report complete comparison row totals (opens in a new tab)
Comparison reports return complete added and removed totals and flag rows that hit the 2,000-row cap, rather than reporting the cut lengths as totals.
-
C# operators keep their CLR names (opens in a new tab)
The C# declaration scanner now names each operator by its CLR symbol (op_Equality, op_Addition, …) instead of the literal name “operator”, so reconstruction checks match .NET metadata.

How I learn a language with small projects
A short walk-through of the way I approach a new programming language: pick a tiny idea, build it end to end, and let the problems teach the syntax. This is placeholder content — replace it with a real article.
