I build production-focused web applications, APIs, automation tools, and AI-powered backend systems. Previously at ProvidusBank, where I worked across application development, API integration, UI development, production support, and technical troubleshooting in a financial technology environment. Currently focused on Python, cloud engineering, DevOps, and AI engineering.

• 🤖 Building AI-powered backend applications with Python, FastAPI, embeddings, vector databases, and RAG
• 🧠 Working with semantic search, Sentence Transformers, pgvector, and LLM-powered document systems
• ☁️ Developing cloud and DevOps skills with AWS, Docker, Linux, and automation
• 🛠️ Building production-style APIs with PostgreSQL, SQLAlchemy, REST APIs, and automated testing
• 🧪 Writing and maintaining automated tests with pytest
• 👀 Open to Software Engineer, Application Engineer, Junior DevOps, Cloud Engineer, and Technical Support roles
• 💬 Ask me about Python, FastAPI, REST APIs, PostgreSQL, Docker, semantic search, or automation

AI-powered document processing and retrieval API built with FastAPI, PostgreSQL, pgvector, Sentence Transformers, and OpenAI.

The system processes PDF and DOCX documents, extracts and chunks text, generates semantic embeddings, stores vectors in PostgreSQL, performs semantic retrieval, and uses Retrieval-Augmented Generation (RAG) to answer questions using relevant document context.

Built features:

• 📄 PDF and DOCX document ingestion
• 🔍 Text extraction and processing
• ✂️ Overlapping document chunking
• 🧠 384-dimensional semantic embeddings
• 🗄️ PostgreSQL document storage
• 🔢 pgvector vector storage
• 🔎 Semantic similarity search
• 📊 Similarity scoring
• 🤖 OpenAI-powered question answering
• 🧩 RAG retrieval and context construction
• 📚 Source-aware answers
• 🚀 FastAPI REST API
• 🐳 Dockerized PostgreSQL development environment
• 🧪 25 automated pytest tests
