Software Studio Website. Created a web studio website showcasing work and service offerings.
Star Group's private system, no public demo.
Calls get transcribed speaker by speaker, then an LLM scores and tags them, and

Client got insights about:
• Detailed calls insights
• Why deals actually pause/die
• Calls tied to the exact Meta/Google campaign
• Finding the weak spots for sales funnel adjustment
• Every sales pipeline leak, now visible and fixableOpenAI - Claude - Speech to text - CRM integration - Bun/Hono - Next.js - Postgres -
