About Me

Mrittick Deb

I’m a Computer Science engineer focused on building production-grade, real-time software systems that integrate intelligent machine learning workflows. My work spans full-stack platforms, distributed architectures, and applied AI — from agentic RAG research systems to real-time collaborative interview simulators and offline-first mobile applications. I specialize in designing scalable backend infrastructures, low-latency event systems, and end-to-end product experiences that move from research ideas to deployed software. Alongside core engineering, I work with machine learning and data science to build practical AI features such as semantic retrieval, fairness-aware evaluation, and NLP-driven analysis. Outside product building, I sharpen problem-solving through competitive programming and deepen security thinking through hands-on offensive learning platforms.
