Akshay Rajhans

I’m an undergraduate software engineering student with hands-on internship experience, focused on building secure, production-grade web systems and cybersecurity tooling. I enjoy turning hard problems into reliable software—especially where performance and security both matter.

In my CSIR – National Physical Laboratory internship, I migrated a monolithic frontend to React.js by decomposing the UI into 12+ reusable components and improving average page load time by ~35%. I also authored 500+ unit tests with pytest, raising test coverage from under 10% to 85%+ across REST API endpoints, business logic, and ORM models.

I strengthened system robustness by refactoring a synchronous Django codebase to fully async with Python asyncio and Django async views, achieving ~3× improvement in request throughput under 200+ concurrent users. I deployed rate limiting and IP-based filtering middleware across 10+ API endpoints, reducing unauthorized access attempts by over 90% and helping mitigate brute-force attack vectors.

Beyond web engineering, I build security-focused tools: I developed AkRecon, a concurrent Go-based reconnaissance CLI, and HashCracker Pro, a FastAPI-powered hash lookup engine designed for real-time analysis. I’m now seeking software engineering or cybersecurity roles where I can help teams build secure, high-performance systems.
