## What I'm looking for

```text
I’m looking for a role where I can build and ship production-ready AI systems and RESTful backends—especially RAG/LLM features, OCR, and reliable deployments—while working with a team that values engineering quality and impact.
```

## About

```text
I’m an AI Engineer and backend engineer with hands-on experience designing RESTful APIs, data-intensive backends, and production-ready AI systems. I currently design, develop, and optimize production-ready AI solutions at SoftylinesDEV, with a focus on turning LLM capabilities into reliable products.

I’ve built a full-stack RAG chatbot MVP using FastAPI, LLMs, and ChromaDB with multimodal document ingestion, and I developed “Equadoc,” a FastAPI-powered AI OCR system for handwritten content and mathematical expressions—converting PDFs/images to LaTeX. I also architected and deployed production backends (e.g., “SoftyBarber”) using secure authentication, background tasks, and Dockerized deployment, while implementing AI speech systems with ElevenLabs and Whisper.
