Harsh Singh

I'm a Full-Stack Developer and Computer Science student (2023–2027) based in Noida. My work focuses on building backend infrastructure and autonomous systems from the ground up.

I prefer writing core logic—like custom neural network topologies or probabilistic data structures—over just wrapping high-level libraries

🛠️ Technical Stack

Languages: JavaScript (ES6+), SQL, C++, Python Backend: Node.js, Express.js, REST APIs, WebSockets Database: MongoDB AI/ML: Autonomous AI Agents, MCP servers, TensorFlow.js, Genetic Algorithms Tools: Postman, Git, GitHub, FFmpeg, ImageKit


🚀 Projects

Built a threat detection pipeline that processes 650K+ URL signatures with ~0.05 ms lookup latency.

  • Uses In-memory Bloom Filters (FNV-1a and MurmurHash2) for fast initial checks.
  • Integrated an ONNX ML engine directly into Node.js for real-time zero-day classification.
  • Optimized with an LRU caching layer to handle high-traffic scanning.

A reinforcement learning simulation built in vanilla JavaScript without PyTorch or TensorFlow.

  • Implemented a custom 5-12-4 feedforward neural network with Tanh activation.
  • Optimized agent behavior using a 1+ genetic algorithm with Gaussian mutation ($\sigma=0.2$).
  • Features a procedural traffic engine for testing generalization across stochastic environments.

A mobile-first video feed built with Next.js and TailwindCSS.

  • Handles secure auth via NextAuth.js and data integrity through strict Mongoose schemas.
  • Uses ImageKit API for automated video transformations and thumbnail generation.
