I am a 3rd-year Computer Science student focused on full-stack development and backend architecture. I divide my time between engineering functional, deployed web applications and keeping my core problem-solving fundamentals sharp through continuous DSA practice.

• Languages: Java, C/C++, JavaScript (ES6+)
• Frontend: React.js, Tailwind CSS, HTML/CSS
• Backend: Node.js, Express.js, Prisma
• Databases & Tools: PostgreSQL, MongoDB, Git, GitHub, REST APIs

GirlScript Summer of Code '26 | Open-Source Contributor

• Ranked in the Top 1% globally among 43,000+ developers with 20+ merged pull requests across production codebases.
• Resolved backend database race conditions, patched WebRTC camera hardware leaks, and resolved Next.js middleware vulnerabilities.

Epiqora | Node.js, Express, JavaScript, Gemini AI

• Built a privacy-first, stateless AI web application handling transient image analysis without retaining user data.
• Implemented multi-model LLM routing for token efficiency and a custom jittered exponential backoff mechanism to manage API traffic spikes.

LabourGuard | Node.js, Express, MongoDB, UI/UX

• Co-developed a secure, backend-focused compliance tracker running a core engine to monitor labor hour allocations and legal violations.

I maintain structured, active repositories to track my daily problem-solving progress (200+ problems solved across platforms):

• C++ DSA Practice: Categorized problem implementations tracking algorithmic concepts.
• Java Mastery Journey: Hands-on implementations focused on object-oriented system design and core structures.
