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. Built as a custom internal system tailored to the client’s workflow.

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)

Cover image for Most wellness apps are built
Most wellness apps are built on streaks, badges, and guilt-driven engagement loops. Zillinity is built on the opposite premise: "be and become" — presence over performance, with no gamification mechanics designed to make you feel behind. I designed and built the entire product solo, end to end. Core features include: - mood-based ambient spaces - two distinct journaling modes (Float for free-flow, Swim for guided depth), -- an AI insight layer called The Mirror that synthesizes patterns across spaces, journal entries, moods, and wins tracked On the technical side, I migrated the app from Next.js to React + Vite for improved performance, architected the backend on Supabase, and built out the marketing site separately on Astro. UI/UX was designed in tandem with the engineering. Every interaction pattern was built to reinforce the product's anti-gamification philosophy rather than work against it. My role: Solo founder & full-stack developer — product engineering, system architecture, UI/UX design Tools/Tech: React, Vite, Supabase, Astro, Claude

Cover image for Panopt solves a problem most
Panopt solves a problem most accessibility tools ignore: writing good alt text is tedious, so most images on the web still don't have it. I designed and built a Chrome extension that lets anyone right-click an image and generate a high-quality, contextual alt text description in seconds. I handled the full build solo, product design, frontend, backend, API integration, and the pay-as-you-go credit system (no subscription required, since accessibility tooling shouldn't lock people into recurring billing). Since launch, it's picked up organic installs across more than a dozen countries with zero paid promotion. My role: Solo founder & full-stack developer: product design, engineering, Claude API integration, Chrome Web Store launch Tools/Tech: TypeScript/JavaScript, Plasmo, Chrome Extension APIs, Claude API (Anthropic), Supabase
