I'm a dynamic software engineer with over 5 years of hands-on experience crafting robust, scalable, and high-performance web and mobile applications. I find genuine satisfaction in elegant solutions that span the full technology stack — from refined frontend interfaces to efficient backend systems and thoughtful DevOps practices. Proficient in Laravel, CodeIgniter, Express.js, NestJS, Go Fiber, React.js, and Kotlin, I also bring infrastructure and cloud expertise, along with a growing command of AI agents and LLM tooling. I thrive in fast-paced environments as a fast learner and adaptable problem-solver, consistently delivering clean, maintainable code that drives real business impact.
