Prashant Raj Bista

AI engineer — LLM systems, RAG, computer vision. Biratnagar, Nepal.

Worked on multi-tenant AI platform services: FastAPI microservices, LangGraph forecasting pipelines, Langfuse observability.

Paper Reproductions

DeepSC-S — semantic communication for speech (arXiv:2012.05369). PyTorch, AWGN/Rayleigh/Rician channels, checkpoints on HF.
ADJSCC — wireless image transmission with attention modules (arXiv:2012.00533). One model across SNR 0–20 dB on CIFAR-10, checkpoints on HF.

Projects

LLM Misuse Monitor — async monitoring for jailbreaks, prompt injection, and PII leakage in self-hosted LLM traffic.
Nepali-to-English Speech Translation — wav2vec 2.0 + mBART with prosody preserved. WER 0.41, SacreBLEU 38.84.
