I need an experienced technology specialist who can quickly guide me through key decisions in modern web development. My goal is to walk away with a concise, actionable blueprint that covers: • Recommended tech stack and hosting approach for a small-to-medium web application • High-level architecture diagram highlighting front-end, back-end, and database interplay • A short checklist of security best practices and performance tips I should apply from day one • Pointers to any starter templates, tools, or documentation that will speed up initial setup This is an advisory task rather than hands-on coding; a short call or written brief that distills your expertise will be perfect. When you apply, focus on your relevant web development experience—specific frameworks, projects, and results that show you’ve solved similar challenges before.
