I help businesses turn scattered data into clear, actionable dashboards and automated
systems — and increasingly, into smarter AI-powered tools on top of that data.

OPEN-SOURCE LLM
- Fine-tuning and adapting pre-trained models (Llama, Qwen, Gemma, BERT) for
domain-specific tasks
- Prompt engineering and inference optimization for production use
- Comfortable with LoRA/quantization techniques to run models efficiently
- Integrating fine-tuned or API-based LLMs into real applications — web apps
(FastAPI/Flask backends) and Windows desktop apps (leveraging my existing
.NET background) — so the model becomes a usable product, not just a notebook

DATA & ANALYTICS (my core strength)
- Looker Studio & Tableau dashboards that turn GA4, Google Ads, BigQuery, Shopify,
and CallRail data into decisions your team can act on
- BigQuery pipeline design and optimization, from raw data ingestion to reporting-ready tables
- Advanced SQL: stored procedures, CTEs, aggregate functions, pivots, performance tuning
- ASP.NET / VB.NET web and desktop applications with SQL Server backends

AI & CHATBOTS (growing focus)
- Built RAG-based chatbots and text-to-SQL assistants using LangChain, OpenAI, and
vector search
- Comfortable with prompt engineering and FastAPI-based backends for AI tools

Recent client feedback: "Highly skilled data visualization expert... translates datasets
into clear, actionable insights." "Great job, knows what he's doing."

I communicate proactively, respond within hours, and deliver on time — happy to start
with a small paid trial task if you want to see quality before committing to a bigger project.
