My focus is on solving real business problems by building applications that are reliable, secure, and user-friendly. I follow principles of Clean Code and Clean Architecture, ensuring solutions are not only functional but also easy to maintain and extend. By applying feature-based and vertical slice architectures, I deliver applications that are modular, scalable, and aligned with real business workflows. # Relevant Work Examples - POS System – robust inventory and sales management with reporting and a modern WPF interface - Medication Management System – secure, role-based access with data integrity and audit trails - LibraLoan Library System – advanced search, CRUD operations, and reporting features - Records Management App – WPF + SQLite backend with high-performance CRUD and CSV export # My Approach - Split the application into features (vertical slices), delivering each as a testable release - Follow Clean Architecture to separate UI, business logic, and data layers for long-term maintainability - Apply Clean Code practices to keep the codebase readable, scalable, and easy to extend - Prototype UI – design intuitive interfaces tailored to end users - Core Development – implement secure, optimized backend logic - Testing & Debugging – validate stability, performance, and error handling - Delivery – provide installer (.exe), full source code, and documentation - Post-launch Support – 30 days free bug fixing, plus optional long-term maintenance # My Skills - C# & WPF – building reliable, modern Windows desktop applications - Architecture – Clean Architecture, Vertical Slice, and Feature-based approaches - UI/UX – creating clean, user-friendly interfaces - Databases – MySQL, SQL Server, and SQLite integration - Version Control – Git for collaboration and structured code management - Containerization – Docker for environment consistency - Problem-Solving – practical, efficient solutions for real-world challenges # Collaboration Style I work independently to deliver complete solutions, but I’m equally comfortable collaborating in a team using Git and shared coding standards to ensure smooth workflows. - # Why Clients Choose Me - 7+ years of proven Windows desktop development experience - Strong focus on clean code and maintainable architectures - Structured, milestone-driven process with transparent communication - Emphasis on performance, usability, and security - Ongoing support and maintenance availability 🚀 Whether you need a lightweight utility tool or a full-scale enterprise-grade desktop application, I’ll deliver software engineered with clean architecture and feature-based design, ensuring it grows with your business. ít hơn

I design and build scalable web applications end-to-end—clean frontends, robust backends, and AI integrations that actually work in real products (not just demos). My work often sits at the intersection of web engineering, data, and machine learning, helping businesses automate processes, personalize experiences, and make better decisions. Core strengths: - Full-stack web development (frontend, backend, APIs) - AI/ML integration (LLMs, automation, intelligent workflows) - Cloud-native architecture and scalable system design - Performance, security, and long-term maintainability I’m used to owning projects from idea to launch, improving existing platforms, or stepping in as a senior technical lead when things get complex. Clients value my clear communication, practical decision-making, and focus on delivering results—not buzzwords. If you’re building a web product that needs real AI value, or you want an experienced engineer to guide architecture and execution, I’d be glad to help. ít hơn
