AI-Powered Funnel Automation & Lead Processing System
Designed and implemented an end-to-end automation system for lead capture, qualification, and conversion.
This project focuses on building intelligent funnels that not only collect user data but also process and act on it in real time. I created structured workflows that handle incoming leads, evaluate their quality using AI-based scoring, and route them through the appropriate paths such as CRM pipelines or automated email sequences.
The system includes multi-step funnel architecture, conditional logic, and backend automation flows to ensure each lead is handled efficiently. High-value leads are prioritized and assigned to sales pipelines, while others are automatically enrolled into nurturing campaigns.
I also designed the workflow structure to be scalable and easy to manage, allowing teams to monitor, adjust, and optimize their funnel performance over time.
The result is a fully automated funnel system that reduces manual work, improves response time, and increases overall conversion efficiency.

Interactive Funnels, Quiz Flows & Conversion Systems
Designed and built interactive funnel experiences focused on user engagement, lead capture, and conversion optimization.
This project includes quiz-based flows, onboarding sequences, and multi-step forms that guide users through a structured journey while collecting valuable inputs. The goal was to create a smooth and engaging experience that increases completion rates and drives meaningful actions.
I focused on simplifying complex flows into intuitive steps, using clean UI, clear progress indicators, and responsive layouts across devices. Each interaction was designed to reduce friction and keep users engaged from start to finish.
In addition, I integrated these funnels with backend logic and automation workflows, enabling actions such as lead segmentation, conditional outcomes, and follow-up processes. This ensures the system is not only visually effective but also functionally powerful for real-world use cases.

Designed and developed a modern, high-performance website experience by transforming traditional layouts into clean, conversion-focused pages.
This project focused on improving overall user experience, visual hierarchy, and engagement through structured layouts, strong typography, and interactive elements. I redesigned key sections including landing pages, service blocks, and content areas to make the product more intuitive and visually appealing.
I also built landing page variations optimized for conversions, with clear call-to-actions and smooth user flow. The goal was not just design improvement, but creating pages that guide users effectively and improve engagement.
Additionally, I worked with modern tools to ensure the design is responsive, fast, and easy to maintain, making it suitable for scalable web platforms and future updates.

Developed a modern MP3 metadata editor focused on making music file management simple and intuitive. The app allows users to upload MP3 files through drag and drop or file selection, inspect and edit common metadata tags, attach album artwork, preview the updated track information instantly, and save the edited file directly in the browser. The frontend was built with React, TypeScript, and Vite, with Chakra UI for a responsive interface and Framer Motion for smoother interactions. Metadata parsing and writing were handled with music-metadata and browser-id3-writer, keeping the workflow fully client side.
Tech stack
React, TypeScript, Vite, Chakra UI, Framer Motion, music-metadata, browser-id3-writer, file-saver.
What I delivered
A responsive web app for editing MP3 metadata, album art management, drag and drop upload, real time metadata preview, and client side file export.
