Hi! I’m Taha Karahan, a multi-skilled full-stack developer with a strong passion for turning ideas into powerful digital products. I specialize in Flutter for mobile development, Next.js for modern web apps, and I have hands-on experience building backends using PHP and Python.

My development journey began in 2022, and since then I’ve worked on various projects, ranging from cross-platform fitness apps to e-commerce platforms and custom web solutions. One of my biggest achievements is Just PT, a mobile-first fitness platform that connects users with personal trainers and dietitians. I led the project from concept to launch using Flutter and Firebase, and implemented scalable features such as real-time chat, push notifications, and Google Maps integration.

On the backend side, I have developed custom APIs in PHP (using Laravel and vanilla PHP) and automated scripts in Python for data handling, integrations, and task scheduling. Whether it’s a mobile app, a responsive web platform, or a backend system, I bring performance, scalability, and clarity to every line of code I write.

🛠️ Core Technologies I Work With:
• Mobile: Flutter, Dart
• Frontend: Next.js, React.js, Tailwind CSS
• Backend: PHP, Laravel, Python, Node.js, Firebase
• Databases: Firestore, MySQL, PostgreSQL
• Tools: Git, Figma, Postman, Docker, Firebase Cloud Functions

💡 My Values:
• Clear and timely communication
• Clean, well-documented code
• User-focused design and functionality
• Commitment to deadlines and quality
• Long-term thinking and maintainability

Outside of coding, I’m curious about product design, business, and technology trends. I enjoy solving real-world problems through smart software and working with people who care about their product as much as I do. I live in Europe and collaborate with global clients across time zones.

Work Terms

🕒 Hours of Operation
I am available to work Monday through Friday, from 9:00 AM to 6:00 PM (GMT+1). I am also open to weekend or urgent work upon request. I’m flexible with time zones and always aim to respond within 12 hours or less.

💰 Payment Terms
I prefer to work with milestone-based or hourly payment models using Guru’s SafePay system to ensure transparency and security for both sides. For fixed-price projects, I usually break the work into clearly defined phases, each with its own milestone. I require a funded milestone before work begins.

💬 Communication Style
I believe that clear and consistent communication is key to a successful project. I’m comfortable communicating through:
• Guru messages
• Zoom or Google Meet (for progress calls or demonstrations)

I provide regular updates and deliverables, share screenshots or demos when needed, and always ensure we are aligned on goals before proceeding to the next step.

✅ Commitment to Quality
• Clean, maintainable, and scalable code
• Fully responsive and performance-optimized designs
• Proper documentation if needed
• Post-delivery bug fixes and support for an agreed-upon period

📦 Project Handoff & Delivery
At the end of each project, I deliver all necessary files (code, designs, documentation) via Guru or cloud storage (Google Drive, GitHub, etc.), depending on the client’s preference.

I look forward to working with clients who value quality, clarity, and long-term collaboration.🕒 Hours of Operation
