What I'm looking for

I’m looking for a team where I can build scalable full-stack and AI/LLM features—combining privacy-first LLM integration, robust APIs, and actionable dashboards—to deliver high-impact products with measurable performance and reliability.

I’m an innovative, results-driven Software Developer with 4+ years’ experience spanning front-end, back-end, and cross-platform development. I focus on system architecture, database optimization, and actionable data analysis—then layer in modern AI/LLM capabilities using Google AI Gemini, LangChain, and Ollama to build intelligent, high-performance applications.

At Luxsar Properties, I engineered an intelligent property recommendation engine with Google AI Gemini and LangChain, improving client-portfolio matching accuracy by 40%. I also deployed local LLMs via Ollama for secure, privacy-compliant querying (zero data leakage), automated multi-gigabyte ETL with Pandas, and delivered Tableau dashboards using real-time APIs—while previously migrating a legacy app to Flutter/Dart at Easyshopy and improving retention by 25%.
