ExpertBioScience — Aquaculture & Fish Medicine Platform

Full-stack web platform engineered from ideation to production MVP in 2 days — providing fish medicine info, promoting aquaculture products, and interactive fish farming calculators.

View Live Project

Project Overview

ExpertBioScience is a specialized digital platform built for an aquaculture and fish medicine company to showcase high-quality fish health products, educate farmers on disease prevention, and simplify daily farm calculations. The standout highlight of this project was the execution timeline: from initial requirement gathering and ideation to complete full-stack coding and live production launch, the entire MVP was delivered in under 48 hours. By combining Next.js with Google AI Studio for rapid component design and logic structuring, the project achieved extreme velocity while maintaining high technical standards. Core Capabilities & Features: 1. Digital Product & Medicine Showcase: Organized listings for fish medicines, water purifiers, growth supplements, and disinfectants—complete with dosage instructions, active ingredients, and target species. 2. Interactive Fish Farming Calculators: Custom calculation utilities allowing farmers to calculate pond water volume, stocking density, feed conversion ratios (FCR), and precise therapeutic dosages based on pond dimensions. 3. Disease & Diagnostic Resource: A structured guide helping fish farmers identify common aquatic diseases (fungal, bacterial, parasitic) and select appropriate ExpertBioScience treatments. 4. Modern CI/CD & Deployment: Built with Next.js and Tailwind CSS, version-controlled via GitHub, and hosted on Vercel for lightning-fast performance and global availability.

The Challenge

Aquaculture farmers and fish medicine distributors frequently lack digital access to accurate product parameters, disease diagnostic guides, and reliable calculation utilities for medicine dosages, pond volumes, and feed ratios. ExpertBioScience needed a modern, trustworthy web platform to showcase their aquaculture pharmaceutical product line and empower farmers with practical calculation tools—requiring immediate execution without months of agency delays.

The Solution

Took the project from conceptual ideation to full production MVP in just 2 days. Utilizing Google AI Studio to accelerate development alongside Next.js and Tailwind CSS, I engineered an intuitive digital catalog, disease diagnostic guide, and interactive fish farming calculators. The platform was deployed on Vercel with continuous integration via GitHub.
