Designed and implemented a custom AI-driven lead capture system where customer conversations (chat or voice) automatically collect contact details, qualify leads, and push them into a single sales funnel. The system triggers structured email follow-ups with a human-in-the-loop approval step, allowing small teams to review and control messaging before it goes out. This enabled 1–2 people to manage inbound leads, follow-ups, and scheduling efficiently—delivering big results without adding staff.

Custom AI Content Automation System for Brand Growth Designed and implemented a custom content automation workflow enabling small teams to create and distribute content at scale with minimal manual effort. The system integrates tools like OpenAI, Gemini, NotebookLM, HeyGen, ElevenLabs, and trend research into a single streamlined workflow—allowing one or two people to efficiently produce text, visuals, video, and audio while maintaining brand consistency. What this enables Faster research-to-content turnaround Multi-format content generation Consistent brand voice using templates Reduced dependency on large marketing teams Outcome Significantly reduced content creation time and enabled higher output without increasing headcount.

YouTube Podcast Translator — language access without platform limits We built a custom YouTube podcast translation tool to remove friction caused by YouTube’s native translation limitations. While some newer videos support auto-translation, millions of YouTube videos remain English-only due to creator settings, regional restrictions, or missing prerequisites. This solution bypasses those constraints. Users can paste any YouTube video link — old or new — and receive a translated audio version in their preferred language. How it works: Accepts any public YouTube URL Extracts the original transcript Translates content using LLMs Converts the translation into natural-sounding speech Outputs playable audio The system works independently of YouTube’s translation rules. Supported languages: English, Spanish, Hindi (Designed to expand)
