About Me

Designing systems where software, data, and intelligence converge.

school

The Foundation

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. This focus is reflected in my academic performance, maintaining CGPAs of 9.3, 9.5, and 9.43 across semesters.

Algorithms

I maintain a strong focus on algorithmic thinking and problem solving, earning 4★ in C, 3★ in C++, and 3★ in Problem Solving on HackerRank.

System Architecture

My work spans full-stack development, algorithmic problem solving, and machine learning research. I enjoy designing systems end-to-end — from frontend interfaces and backend services to databases and infrastructure — ensuring that each layer works cohesively within a larger architecture.

hub

Tech Ecosystems

I actively strengthen my technical foundation through continuous learning and experimentation across modern technologies including JavaScript ecosystems, Python, React, Node.js, databases, cloud platforms, and AI frameworks. Rather than treating tools as isolated skills, I focus on understanding how technologies integrate to form complete software ecosystems. This includes how frontend frameworks interact with backend services, how data flows through applications, and how infrastructure supports scalable deployments. Through structured learning, project development, and experimentation, I continuously expand my exposure to different programming paradigms, frameworks, and architectural patterns. This approach helps me build a deeper understanding of the broader software landscape rather than limiting myself to a single stack.

Machine Learning Research

Alongside software development, I am actively involved in ML research on urban air quality prediction, exploring models that analyze pollutants (VOCs, O₃, NOx) using environmental and temporal data. The project investigates how data-driven techniques can help understand complex patterns and support better forecasting.

Long-Term Vision

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.

Research & Publications

Machine Learning March 2024

Optimizing Distributed Inference in Latency-Critical Edge Environments

Investigated novel partitioning strategies for deep neural networks across heterogeneous edge nodes. The proposed model reduces communication overhead by 34% while maintaining model accuracy in dynamic network conditions.

Operating Systems November 2023

Predictive Cache Management for High-Frequency I/O Operations

Developed a heuristic-based prefetching algorithm for non-volatile memory architectures. This research demonstrates a significant reduction in tail latency for database workloads under heavy concurrent access.
