At Defence Research and Development Organisation (DRDO), I architected a distributed, multi-core Differential Fault Analysis engine in C++ and OpenMP that reduced the key-recovery search space by 64 orders of magnitude and cut runtime to under five minutes.
I also designed a dynamic, key-tethered S-box generator to harden an AES-128 implementation against algebraic cryptanalysis. It produced more than 100 million false-positive candidate paths per branch.
On Controlplane, an ongoing RAG platform, I optimized hybrid retrieval and ingestion to achieve sub-200ms retrieval for 95th-percentile requests. My projects also include a privacy-first code RAG system and EduDash, a full-stack educational management dashboard.
