Building the backbone of digital products.
I'm a Full Stack Engineer and Tech Lead specialized in designing and scaling complex web applications. Over the past 6+ years, I've built everything from multi-tenant SaaS platforms supporting 150+ modules to high-traffic API services with 500+ endpoints.
My core stack revolves around Laravel, Vue.js, MySQL, Redis, and AWS — but I'm equally comfortable with domain-driven design, clean architecture patterns, and leading engineering teams through agile workflows.
More recently, I've been diving deep into Generative AI, LLM integrations, and prompt engineering — blending traditional software craft with the cutting edge of AI technology.
