About Me
Designing systems where software, data, and intelligence converge.
I am a Computer Science undergraduate focused on understanding and building complex digital systems. My academic journey has been driven by curiosity about how software, data, and infrastructure interact to create scalable and intelligent applications — reflected in CGPAs of 9.3 · 9.5 · 9.43 across semesters.
Strong focus on algorithmic thinking — earning 4★ in C, 3★ in C++, and 3★ in Problem Solving on HackerRank.
I design systems end-to-end — from frontend interfaces and backend services to databases and infrastructure — ensuring each layer works cohesively within a larger architecture.
I actively strengthen my foundation across modern technologies — JavaScript ecosystems, Python, React, Node.js, databases, cloud platforms, and AI frameworks. I focus on understanding how technologies integrate to form complete software ecosystems, not treating tools as isolated skills.
Actively involved in ML research on urban air quality prediction, exploring models that analyze pollutants (VOCs, O₃, NOx) using environmental and temporal data. Investigating how data-driven techniques can support better forecasting at city scale.
My long-term goal is to grow into an engineer capable of designing intelligent systems, building scalable software infrastructure, and contributing to technologies that operate at real-world scale.
