What I'm looking for

I'm looking to build end-to-end AI systems, agentic workflows, full-stack applications, and automation that work reliably in production.

I've delivered 100+ projects for international clients through Upwork, Fiverr, and direct engagements, spanning full-stack web development, data extraction, browser automation, API backends, and AI workflow design. I build with React.js, Python, FastAPI, Flask, Django, Express.js, and Tailwind CSS.

At Sonelgaz, I maintain ITRON-based meter-reading infrastructure and build Django and FastAPI applications for high-volume data flows, helping sustain 99.9% uptime. I also create robust Scrapy, Selenium, and Playwright scrapers, Chrome extensions, and agent-based automation pipelines using n8n, LangChain, and LangGraph.
