Available for Summer 2026 Internship

I build systems that
scale, solve & ship.

Software Engineering undergrad at GL Bajaj. I obsess over clean architecture, algorithm efficiency, and turning complex real-world problems into elegant, production-ready products.

Engineer first. Builder always.

I'm Shubh Raj Singh, a final-year CSE student at GL Bajaj with a relentless focus on building software that solves real problems at scale. I don't just write code — I architect solutions.

My foundation is built on strong DSA fundamentals (500+ problems, top 5% globally on LeetCode) combined with hands-on full-stack development experience. I've shipped features used by thousands of users through internships at HCLTECH.

I'm drawn to problems where performance, scalability, and design thinking intersect — whether that's optimizing a graph traversal algorithm or building a distributed caching layer for a fintech API.

Currently seeking SWE internship/full-time roles at top-tier companies. I want to work on engineering challenges that push limits, not just maintain legacy code.

🎯
Problem Solver at Core
Competitive programmer. Instinctively break down ambiguous problems into structured, optimal solutions before writing a single line of code.
⚙️
Systems Thinker
Deep interest in distributed systems, OS internals, and databases. I understand what happens under the hood — and why it matters.
🚀
Product-Oriented Builder
I ship. 8 projects deployed. Measure success by user impact, not lines of code. Obsessed with developer experience and clean APIs.
🤝
Collaborative Mindset
Led a 6-person dev team for the college technical fest. Comfortable with code reviews, technical documentation, and agile workflows.

Things I've built

Real problems. Real impact. Every project solves a specific pain point and was deployed in production or used by real users.

★ Flagship Project
Problem: Delayed and error-prone manual diagnosis of brain tumors from MRI scans can impact timely treatment decisions.
NeuroScan · Brain Tumor Detection

Built a full-stack AI-powered application that detects and classifies brain tumors from MRI images using deep learning models. The system automates image preprocessing, feature extraction, and classification to assist in accurate and faster diagnosis.

📈 Impact: Achieved high classification accuracy on MRI datasets, reduced manual analysis effort, and enabled real-time predictions for medical image evaluation.
