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

Data modeling in Microsoft Power BI is the foundation of accurate and high-performance dashboards. 1. Use Star Schema Fact table → numeric data (Sales, Revenue) Dimension tables → descriptive data (Customer, Product, Date) Keep fact in center, dimensions around it 2. Relationships (When to Use What) One-to-Many (1:*) → Best practice (Dimension → Fact) Many-to-One (*:1) → Same as above, reversed view One-to-One (1:1) → Rare, use only if necessary Many-to-Many (:) → Avoid; use bridge table instead 3. Filter Direction Single direction → Recommended (Dimension → Fact) Bi-directional → Use only for complex cases 4. Data Preparation Clean data in Power Query Remove duplicates, fix types, handle nulls 5. DAX Measures Use measures (SUM, CALCULATE) over columns 6. Best Practices Use a proper Date table Keep dimension values unique

Cover image for Discover FlexCare: Revolutionizing Clinic Website Experience

I’m building FlexCare — a modern clinic website focused on better bookings and smoother patient experience. To make things more transparent, I’ve deployed a live frontend prototype (~40% complete). So far: • Landing page mockup • About, Services, Blog & Team pages (UI ready) • Core UI/UX structure • Early booking flow concept This helps visualize the final product before full development. Still a lot to build, but sharing early to improve faster 🚀 👉 Live preview available in the comments — would love your feedback. 👉 If you're building a clinic website, happy to share insights.

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 I usually craft traditional action

I usually craft traditional action trailers, but I challenged myself to build a cinematic, high-octane YouTube Shorts trailer (9:16) using advanced AI generation, dynamic editing, and sound design. Do you preferer editing and generating movie's official trailer or the Full AI Action Movie 🍿 (https://higgsfield.ai/contests/make-your-action-scene/submissions/40f65184-dd97-4846-b560-4f763324bc14?utm_source=contest_submission_page_copy_link&utm_medium=share&utm_content=contest_submission)? (P.S. I’m currently taking on new projects! If you need cutting-edge AI filmmaking, official movie trailer editing, 3D animation, or video editing, let's collaborate.)

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.
