Case Studies
Real Problems. Real Solutions.
Each project here was a production challenge — not a coding exercise. Here's what the problem was, how I solved it, and what shipped.
MSZ Education Platform
A connected education system with admin operations, student mobile access, and a public-facing portfolio site.
Student mobile app included · Mobile student experience
Problem
MSZ needed one product ecosystem instead of disconnected tools: an admin panel to manage operations, a student mobile app for daily use, and a portfolio website to present the organization clearly online.
Solution
Built the project as a connected multi-surface system with an admin dashboard for internal management, a mobile app focused on the student experience, and a portfolio site to communicate the brand and offerings publicly.
Results
- ✓Admin workflows moved into a dedicated internal panel
- ✓Students got a mobile-first experience for day-to-day use
- ✓Public portfolio presence aligned with the product ecosystem
- ✓Single project delivery across internal, mobile, and public-facing surfaces
Fitraat — Behavioral SaaS Platform
Helping adults break addictive patterns with structured 40-day programs
Mobile app included · React Native / Expo
Problem
Needed a full SaaS platform to deliver structured behavioral change programs — with daily task unlocking, progress tracking, emergency support, a community feed, and a payment gateway, across both web and mobile.
Solution
Built the entire platform from scratch: Next.js web frontend, React Native mobile app (Expo), and a Strapi backend deployed on AWS (EC2, S3, RDS). Implemented SSL Commarz payment gateway, 40-day task unlock system, real-time feed, and pro membership flow.
Results
- ✓Full SaaS with free & paid tiers live in production
- ✓SSL Commarz payment gateway integrated and processing real transactions
- ✓React Native mobile app shipped alongside the web platform
- ✓Deployed on AWS — EC2, S3, RDS handling real user traffic

I build production-ready systems — not prototypes. If you need a developer who understands the full stack and can ship real products, let's talk.
