Lekkala Ganesh

I've shipped end-to-end AI and web applications as a freelance Full-Stack & AI Engineer, building React and Next.js clients, FastAPI and Express services, and secure PostgreSQL data models on Supabase.

I engineer practical AI features including multi-provider LLM fallback from GPT-4o to Gemini and OpenRouter, real-time SSE voice streaming, embedding-based retrieval, ONNX model serving, and rubric-driven LLM evaluation. My public projects include an ATS Resume Optimizer with TF-IDF semantic matching and 269 pytest tests, Healthy Chef invoicing with server-side GST calculations, and Lite-Vision real-time face analysis serving four ONNX models.

Previously, I delivered six MERN projects at Slash Mark IT Solutions and built regression and classification models with scikit-learn and Pandas at Bharat Intern. I care about reliable delivery through automated testing, CI, secure schema design, responsive interfaces, and WCAG 2.1 AA accessibility.
