I’m a Senior Software Engineer with over 6 years of experience building full-stack, high-performance web applications. I focus on system architecture design, database management, and delivering reliable solutions that keep up with increasing user demands.

In my current role (Apr 2021–Present), I develop scalable applications and work closely with designers and product managers to align technical decisions with business goals. I optimize database queries and application performance, implement automated processes (like report generation), and reduce manual work to improve overall efficiency.

I also integrate third-party APIs and build RESTful backend services to enable seamless system communication and expand functionality. I lead code reviews and contribute to architecture decisions, ensuring strong code quality and best development practices.

Previously, as a Full-Stack Developer (Sep 2020–March 2021), I built and maintained websites and new features end-to-end using Laravel, Yii, Node.js, Vue.js, and WordPress. I diagnosed and resolved technical issues, improved stability, and worked to deliver better performance, usability, and user experience.
