Summary
I am a seasoned Full Stack Software Engineer with professional experience since 2016, specializing in building scalable, high-performance, and maintainable software solutions across backend, web, and mobile platforms. Throughout my career, I have developed and contributed to large-scale products that have collectively served over 500,000 users. My strength lies in end-to-end software development — from designing robust system architectures and efficient APIs to building responsive web applications and polished mobile experiences. Several of the mobile applications I have worked on have achieved a 4.9-star rating on both the Google Play Store and Apple App Store, reflecting a strong commitment to product quality, performance, and user satisfaction.
In today’s era of rapid AI-assisted development, I understand how to build software based on best practices, clean architecture, and long-term maintainability, rather than relying on shortcuts or unstructured “vibe coding.” I know how to use AI as a highly effective engineering assistant — accelerating development, improving productivity, and supporting problem-solving — while still applying strong technical judgment, code quality standards, and sound software design principles.
