# Project Discovery & Quick Estimate with Arturo Nava

> A concise discovery session to evaluate project requirements, assess technical feasibility, and prepare an initial quote. Topics covered: High-level project objectives, core problem, and expected deliverables. Architecture feasibility, tech stack recommendations, and dependencies. Next steps for scoping, formal budget estimation, and timeline. Note on Spoken Language: My native language is Spanish. While my written technical English is fully proficient, my live conversational English is currently developing. I use real-time AI speech translation tools during calls to ensure precise and fluid communication. You are welcome to speak in English or Spanish.
