AI & Backend Engineer
Computer Science engineer focused on artificial intelligence and scalable backend systems. I build production-ready RESTful APIs with FastAPI, fine-tune LLMs, and optimize computer vision for CPU-based environments — delivering high-performance, end-to-end software.

A selection of systems I've architected end-to-end — from model selection to production deployment.
End-to-end RAG system parsing complex PDFs (text + charts) via a dual-stream embedding architecture (Sentence-BERT & CLIP). Integrated a 4-bit quantized Mistral-7B with Chain-of-Thought prompting to cut hallucinations by 25%, hitting sub-100ms retrieval and a 0.96 NDCG@5 with a BERT cross-encoder.
Hugging FaceCross-EncoderHigh-performance vehicle tracking hitting 60+ FPS on standard CPU hardware — no GPU required. MOG2 background subtraction and centroid tracking quantify traffic flow with 95% accuracy.
OpenCVMOG2Centroid TrackingFull-stack agentic platform on FastAPI + Next.js 15 using Llama 3.1 to turn PDF resumes into Pydantic-validated JSON. FAISS + BGE embeddings power context-aware job matching, with SSE streaming roadmaps chunk-by-chunk.
FastAPINext.js 15FAISSBGESSEMultimodal ML system predicting genetic traits and familial connections. A Siamese network with contrastive loss verifies kinship via fingerprint similarity, while MTCNN + a fine-tuned MobileNetV2 handle face detection and skin-tone classification on CelebA.
