About

Professional summary

I am a full stack software developer with four years of experience building, maintaining, and optimizing production web applications. I am currently focused on backend development, artificial intelligence integrations, and practical automation solutions.

I have strong experience working with existing codebases, diagnosing production issues, optimizing databases and APIs, and delivering features that support real business needs. I am comfortable taking ownership of applications from requirements gathering through deployment, maintenance, and incident resolution.

In my current work, I build RAG-based document query systems, AI-powered workflows, semantic search capabilities, and integrations between language models and internal tools. I have worked on document ingestion, embeddings, response streaming, source citations, and Python-based web scraping.

My web development background includes PHP, WordPress, JavaScript, React, MySQL, REST APIs, and custom e-commerce data models. I have maintained dozens of production applications and improved performance on heavy pages through SQL, application logic, and frontend optimization.

As a freelancer, I have delivered custom projects for more than 30 clients, managing technical implementation, project scope, estimates, and delivery independently. I also enjoy building interactive experiences and games using Godot and Three.js.
