Cover image for 3D Molecular Intelligence: Accelerating Drug

3D Molecular Intelligence: Accelerating Drug Discovery through Predictive Analytics The Impact: This project addresses a critical bottleneck in pharmaceutical research: determining molecular solubility (logS). By replacing slow, expensive lab tests with high-precision machine learning, this system enables scientists to screen thousands of compounds in seconds, significantly reducing the cost and time required to bring new life-saving drugs to market. Drastic Cost Reduction: The predictive pipeline reduces early-stage experimental screening costs by 70–90%, allowing research teams to focus resources on the most promising drug candidates. High-Precision Forecasting: Utilizing a hybrid 3D feature engineering approach, the system achieves a remarkable 91.3% accuracy (R² score) in predicting solubility, providing a highly reliable alternative to physical testing. Accelerated R&D Cycles: By automating the identification of viable molecules, the tool dramatically shortens the "hit-to-lead" time in pharma and materials science, getting products to market faster. Empowering Researchers: I deployed a professional Streamlit dashboard featuring an interactive 3D molecular viewer. This allows non-technical chemists to visualize complex structures and make data-driven decisions without needing to write a single line of code

Cover image for I created this website using

I created this website using vibe coding, focusing on making the platform simple, clean, and easy for visitors to enjoy. My goal was to design a smooth blog experience where users can read content without distraction and navigate effortlessly across pages. For this project I handled the full setup, including layout structure, content placement, and overall site flow, making sure everything look organized and works properly. I also paid attention to user experience, so the site feels friendly and modern rather than complicated or heavy. This project show my ability to build and manage blog-style websites, combine creativity with functionality, and deliver a result that looks professional while staying easy to use. I use this site as a demo to show how I can help clients create or manage similar platforms with confidence and care.

Cover image for A cinematic 3D visualization of

A cinematic 3D visualization of the Bugatti Bolide, created to explore dynamic lighting, atmospheric conditions, and high-contrast automotive presentation. The scenes were rendered using Lumion, with a strong emphasis on night environments, wet surfaces, reflections, and dramatic light behavior to enhance visual impact. The 3D model was sourced from an online library and used exclusively for visualization and rendering purposes, not for original vehicle design. This work reflects a growing interest in real-time rendering, environmental storytelling, and high-performance automotive CGI.

Generic AI builders like Bolt, Lovable, or Anti-Gravity are impressive for demos, but they choke on real-world complexity. The Challenge: Build a fully automated, AI-powered Business Directory & Listing platform capable of rivaling giants like Thumbtack. The Result: In just under 6 months, I and my team engineered CT Home Proz is the 2nd true pioneer of AI-powered contractor marketplaces after Thumbtack. Why this breaks the mold: a) 100% Automated: The system connects Homeowners to Contractors without manual intervention. b) Complex Logic, Simple UI: While the backend handles thousands of logic gates which AI auto-coders fail to process, the frontend is effortless for users. If you want a landing page, use an AI builder. If you want a Scalable Platform with complex business logic that actually works, you need an Engineer. 🏗️

Cover image for Engineered with VS Code, PHP, Angular, Custom Framework, SQL...

Engineered with VS Code, PHP, Angular, Custom Framework, SQL, Python, and elite LLMs (Gemini, Claude), this isn't a generic AI wrapper. Guided by a six figures marketer, my team and I built a compliant B2B growth engine that replaces expensive middleware (n8n/Make), saving over $12k/mo. It scrapes leads, sends spam-proof emails in your exact brand voice, and auto-generates blogs with JSON-LD Schema for GEO ranking. The Flex: Custom Python logic turns 7 hours of marketing into 15 minutes, handling strict compliance rules that no prompt or drag-and-drop Ai app builder can touch. 🚀 Hit me up on Contra to build the complex apps that AI app builders can't. Or, I and my team can pick up exactly where your AI builder or 'vibe coding' got stuck.
