Hi, I'm Peshal Nepal, an AI/ML Engineer, applied researcher, and Data Scientist with 5+ years shipping production AI across LLMs and agents, NLP, computer vision, time-series forecasting, and generative AI.
I specialize in taking models from notebook to production: fine-tuning Transformers (BERT, LLaMA), building RAG and multi-agent systems with LangChain, LangGraph, and vector search, deploying real-time computer vision on edge and cloud, and wiring it all together with FastAPI, Docker, MLflow, and CI/CD on AWS and Azure. Currently at Nexopta, where my work powers an AI assistant platform serving 30,000+ users.
What sets me apart is depth: I read the papers and re-implement architectures (Transformers, GANs, U-Net, YOLO) from scratch in C++ and Python, because I'd rather understand the math than memorize a framework. I love turning messy data into useful decisions, and occasionally convincing stubborn datasets to cooperate.
Built a business-focused AI assistant platform that lets company employees use their organization's own AI agents for internal support, customer interactions, and daily work tasks. Designed a multi-agent, multi-knowledge-base system using LightRAG for standard clients and Azure AI Search with Neo4j for enterprise clients needing richer retrieval and structured knowledge graphs. Expanded the platform across chat, voice, website widget, web chat, and Vapi phone channels, giving clients flexible ways to deploy AI assistants across customer and internal workflows. Integrated automation and backend services with Activepieces, FastAPI, SQLAlchemy, Redis, and Azure, scaling the platform to 30,000+ users.
Built an AI-powered Applicant Tracking System using BERT fine-tuned for Named Entity Recognition on a custom Doccano-labeled resume dataset, cutting screening time by 40%. Shipped a document classification system for mining clients that auto-filled forms by project phase, lowering review costs by 60%. Deployed services on AWS ECS with Docker and CI/CD.
Built a real-time CCTV security system on Raspberry Pi using YOLOv5 for object detection and FaceNet for face recognition, improving company security by 70%+. Developed a virtual try-on pipeline with U-Net segmentation and a conditional GAN, lifting customer engagement by 40%. Implemented core CV algorithms in C++ (SURF, ORB, image transforms) and built NN/CNN from scratch. Led weekly AI study sessions on AlexNet, VGG, RNN, and LSTM.
Portfolio projects aligned with resume highlights and measurable outcomes.
Built a real-time multi-camera AI detection system for RTSP feeds with per-camera processing, detection overlays, and scalable event-driven backend workflows. Designed for monitoring use cases with support for multiple streams, low-latency inference, and production-oriented deployment.
Built a multi-model trading system combining TS-Mixer forecasting and crypto sentiment analysis to improve decision quality across volatile markets.
Designed a Raspberry Pi to cloud workflow that captures pose keypoints, syncs to S3, and powers LSTM-based exercise classification and rep counting for physiotherapy use cases.
Built an ATS with entity extraction and job-match scoring to automate candidate screening and improve recruiter throughput.
Modelled CDC chronic disease records to predict state-level arthritis trends and drive an early-alert dashboard for public-health planning.
Implemented neural-network building blocks from scratch in both C++ and Python to understand core deep-learning mechanics beyond framework abstractions. Focused on forward propagation, gradient-based learning, parameter updates, and reusable model components to build strong intuition for how neural networks train internally.
Built and explored YOLO-style object detection concepts from a learning-first perspective, breaking down the detection pipeline into understandable components such as feature extraction, prediction heads, bounding-box logic, and training/inference flow. Designed as a strong foundation for production detection systems later used in real-time CV work.
Implemented and experimented with Transformer-based sequence modeling components to deepen understanding of modern NLP architectures. Explored attention-driven representation learning and token-level sequence processing as a bridge toward LLM and generative AI engineering work.
Built a human segmentation pipeline using a U-Net model trained on the COCO dataset. Implemented data preprocessing, mask generation, training/evaluation loops, and visual inspection of predicted masks to validate pixel-level performance. This work strengthens the foundation for virtual try-on, scene understanding, and production CV segmentation workflows.
Explored recurrent neural networks for sequence and temporal learning tasks, focusing on how hidden states encode context over time. Helped build a solid understanding of sequence modeling concepts later applied in LSTM-based projects and time-dependent prediction workflows.
Curated and implemented a broad set of classical computer-vision and image-processing exercises, including edge detection, feature detectors, affine transforms, line detection, gradient thresholding, image rotation/ flipping, PCA, k-means clustering, and logistic regression. This repository showcases the engineering fundamentals that support robust modern CV system design.
Studied foundational GAN research papers and implemented generative adversarial networks from scratch to understand adversarial training dynamics, generator/discriminator interplay, loss functions, and stabilization techniques. Built and trained custom GAN architectures to visualize how learned representations generate realistic samples and evaluated model behavior through iterative experimentation.
Built notebook-based classification experiments to practice model training, evaluation, and iterative improvement across core deep-learning workflows. This project collection demonstrates hands-on experimentation discipline used later in production-focused ML and CV systems.
Fine-tuned a 7B LLaMA 2 model on custom conversational data to improve contextual task handling and reduce manual support for routine queries.
Built a task-oriented conversational assistant using the RASA open-source framework, covering intent classification, entity extraction, custom actions, and multi-turn dialogue management. A pre-LLM exploration of conversational AI fundamentals that informs how I design modern agentic and tool-using systems today.
Developed a CCTV security system with object tracking and face recognition, deployed as Docker microservices for reliable real-time alerts.
Designed and built a custom GPS tracking collar with integrated temperature and heart-rate sensors for real-time animal location and vitals monitoring. Implemented microcontroller firmware in C, wireless data transmission, and cloud upload to power a remote monitoring dashboard. Demonstrates end-to-end systems thinking, from hardware and embedded firmware up to cloud integration.
