Hi, I'm Abderrahemane
I'm an AI Engineer and Full Stack Developer studying Computer Science Engineering at ESTIN (Algeria). I combine machine learning research with modern software engineering to build scalable, AI-powered products that solve complex real-world problems.
My background spans the entire product lifecycle: from data curation, model fine-tuning (QLoRA), and vector search (CLIP + FAISS) to production web applications built with Next.js, NestJS, FastAPI, and PostgreSQL.
Current Focus & Status (Now)
Full Stack Developer @ Primaria Tech
Building agile web applications, optimizing API latency, and collaborating in cross-functional software teams.
RAG & LLM Engineering Research
Exploring multimodal representations, synthetic instruction datasets, and PEFT fine-tuning pipelines for specialized domains.
Areas of Expertise
Large Language Models & RAG
Fine-tuning open source weights, dense retrieval, and grounded generation with verifiable citations.
Multimodal AI Systems
Cross-modal image/text embeddings, FAISS vector indexing, and real-time visual product discovery.
Full Stack Web Architecture
Next.js App Router, NestJS modular backends, TypeScript type-safety, and WebSocket event pipelines.
Graph Representation Learning
Network analysis with Node2Vec, link prediction, and interactive Cytoscape network visualisations.
AI-Powered Anomaly Detection
Unsupervised ML pipelines, log stream classification, and explainable AI metrics with SHAP.
Production Engineering & MLOps
Dockerized microservices, Redis caching, structured logging, and robust API design.
Professional Timeline
The evolution of my engineering and machine learning journey.
High School Graduation
Graduated from high school with a focus on science and mathematics, with a very good academic record.
Started Computer Science at ESTIN
Enrolled in the Computer Science Engineering program at École Supérieure en Sciences et Technologies de l'Informatique et du Numérique (ESTIN), Béjaïa.
First Full-Stack Projects
Built my first MERN-stack projects, learning React, Node.js, Express, and MongoDB. Focused on clean architecture and REST API design.
Discovered AI & Machine Learning
Completed the Machine Learning Foundations certification on Coursera and started building ML models with Python, Scikit-learn, and TensorFlow.
AI Engineer & ML Specialization
Earned multiple certifications including ML Specialization (Stanford/Coursera) and AI Engineer Associate (DataCamp). Worked on HealSeek and Edu+ as full-stack projects.
Freelance & Advanced Projects
Delivered Mon Atelier (workshop management system) as a freelance project. Deepened expertise in NestJS, FastAPI, and production ML deployment.
Freelance Data Analyst — Research Statistical Pipeline
Conducted full statistical analysis pipeline for a PhD researcher in plant biology, producing publication-ready outputs including Two-Way ANOVA, PCA, and correlation matrices for drought tolerance rankings.
