Hi, I'm Rinas.Self-Taught AI EngineerBuilding intelligent systems.

I build AI applications, machine learning systems, and software solutions — training models, shipping LLM agents, and turning research into production. Currently deep in Python, ML, and LLM engineering.

About

A self-taught engineer, building in public.

No traditional path, no shortcuts. I'm learning the full stack of modern AI — from linear algebra to production LLM systems — one project at a time.

Why I started

I saw AI reshaping every industry and refused to sit on the sidelines. I started with Python, kept going, and never stopped.

How I learn

Books, papers, docs, YouTube, and — most of all — shipping. I turn every concept into a project until it clicks.

The goal

Become a professional AI Engineer. Get hired on the strength of my work: real systems, clean code, measurable impact.

What I build

LLM agents, ML pipelines, APIs, and end-to-end AI products. I care about latency, cost, and reliability — not just demos.

Stack

The tools I use to ship AI.

A living stack. I add depth every week — from fundamentals to production systems.

Selected Work

Projects that ship, not just demos.

Each project starts with a real problem, ends with a working system, and is documented on GitHub.

Multi-Agent · LLM

AI Trading Agent

Retail traders drown in noise and lack structured, risk-aware analysis.

Multi-agent AI system that analyzes markets, manages risk, and generates trading insights. Specialized agents (research, risk, execution) coordinate through a shared plan and memory.

RAG · Tools

Personal AI Assistant

General chatbots forget context and can't act on your real data.

An assistant that reasons across your files, retrieves knowledge with hybrid RAG, and executes tools — calendars, search, code — through a typed function-calling layer.

ML · Production

Churn Prediction Pipeline

End-to-end ML pipeline: feature store, gradient-boosted models, evaluation dashboards, and a REST API deployed on the cloud with monitoring.

NLP · Fine-tuning

Sentiment NLP Engine

Fine-tuned transformer on a curated domain dataset, with a lightweight inference service and a labeling loop to improve accuracy over time.

Journey

Learning in the open, compounding daily.

A roadmap I revisit every quarter. Every entry is backed by projects, notes, and commits.
