Full-Stack Web Development
Design and delivery of production-grade full-stack applications using React, Next.js, TypeScript, Node.js (Express), PHP (Laravel/Core), and Python (FastAPI), covering system design, API development, database architecture, and frontend delivery.
AI & Prompt Engineering
Expertise in LLM optimization, structured prompting workflows, GPT-4, Claude, and Gemini APIs, Chain-of-Thought reasoning, and RAG Pipelines to accelerate feature delivery and automate development workflows.
RESTful API Design & Secure Authentication
Architecture of scalable RESTful APIs with JWT-based authentication, RBAC, CSRF protection, and secure session management, achieving zero unauthorized access incidents across deployed systems.
Mobile Development (Android)
Development of Android applications using Java and Kotlin with mobile-first UI and offline-first architecture, enabling expanded user reach in low-connectivity environments.
Database Design & Optimization
Design and optimization of relational database schemas using MySQL and PostgreSQL, including indexing, query tuning, and normalized schema design to improve data-heavy endpoint performance.
DevOps & Cloud Infrastructure
Deployment and management of cloud-native applications using AWS (EC2, S3, Lambda), Docker, Kubernetes, and CI/CD pipelines, maintaining high test coverage on critical backend modules.
Software Architecture
Application of Microservices, MVC, and Event-Driven Design patterns to build scalable, maintainable systems with clear separation of concerns.
Agile / Scrum Methodology
Application of Agile/Scrum across all projects including sprint planning, iterative delivery, and stakeholder demos, ensuring on-time completion with zero scope creep.
Tools & Collaboration
Proficient use of Git, GitHub, Postman, VS Code, IntelliJ IDEA, Power BI, and collaborative workflows across distributed, cross-functional teams.

Projekthistorie
Architected and shipped 5 production-grade full-stack applications end-to-end, covering system design, API development, database architecture, and frontend delivery. Designed RESTful APIs with JWT-based authentication and RBAC. Built multi-role admin dashboards, optimized relational database schemas, integrated AI-assisted development workflows, and delivered mobile-first Android applications. Applied Agile/Scrum across all projects.
Engineered a full-stack donation management platform with multi-role authentication (admin, donor, manager) and a real-time dashboard for fund tracking using PHP, MySQL, JavaScript, Bootstrap, JWT Auth, and RBAC Admin Panel. Designed a normalized relational schema cutting data retrieval time by ~35%. Implemented CSRF protection and secure session management, achieving zero security incidents post-deployment.
Built a web-based POS system handling inventory management, sales transactions, and receipt generation with a responsive UI using Java (Spring MVC), MySQL, HTML/CSS, and JavaScript. Implemented MVC architecture enabling 50% faster feature iteration. Reduced average transaction processing time by an estimated 45%.
