• Algorithmic Problem Solving: LeetCode Knight rank[cite: 1] with a peak rating of 1920[cite: 1] and 1000+ problems solved across LeetCode, Codeforces, and GeeksforGeeks[cite: 1].
• Systems Engineering: Developing low-level C modules on Linux[cite: 1], handling memory management[cite: 1], and debugging high-throughput runtime code using GDB[cite: 1].
• Applied GenAI: Building framework-free retrieval pipelines[cite: 1], custom vector search components[cite: 1], and media processing models[cite: 1].

Framework-free modular RAG pipeline featuring 768-dimensional BGE embeddings[cite: 1], PGVector storage[cite: 1], and cross-encoder reranking[cite: 1]. Includes an automated evaluation benchmark tracking Hit@K, Precision@K, Recall@K, and MRR[cite: 1].

Multilingual video dubbing workflow utilizing WhisperX, GPT-3.5, Edge TTS, Demucs, and FFmpeg[cite: 1]. Cuts inference latency by 2.5x via chunk-wise speech synthesis[cite: 1] and boosts synchronization accuracy by 40%[cite: 1].

Shared-state Token Bucket rate limiter built on Redis and exposed via FastAPI middleware[cite: 1]. Uses atomic Lua scripts inside Redis to eliminate race conditions under concurrent load[cite: 1].
