I’m a Software Developer and AI Integration Engineer who works at the intersection of backend logic, data systems, and AI-powered automation. As an AI Integration specialist, I focus on building reliable workflows that translate model behavior into real-world outputs.

In my current role, I trained and evaluated LLMs through human feedback and response assessment. I also performed multimodal data annotation (text, audio, video), then supported dataset validation and quality assurance to keep training inputs and evaluations consistent.

As a Freelance Data & AI Specialist on Upwork, I’ve completed 10+ data cleaning and structuring projects using Excel and Python. I’ve also delivered AI training data labeling/annotation, engineered prompts for GPT-4 and Claude-based applications, and provided integration consulting for automating workflows with OpenAI and Anthropic APIs.

I bring this expertise into product work through projects like my AI Virtual Streamer (Node.js, React, Claude/OpenAI APIs) with persistent memory and n8n pipelines. I also build lead-generation and Shopify import automation systems—using GPT-4o scoring, Gmail API outreach, webhook-driven validation, SEO generation, and Dockerized pipelines—so results are accurate, scalable, and low-maintenance.
