About

Professional summary

I am a Senior Full-Stack Developer with an 8+ year track record and a deep specialization in backend engineering, API architecture, and DevOps. I design and scale enterprise-grade web applications utilizing JavaScript/TypeScript (Node.js, NestJS, Express, Next.js) and PHP (OOP, Laravel, Custom WordPress, WooCommerce). Beyond writing robust code, I manage the infrastructure that powers it—leveraging extensive hands-on experience in cloud environments (AWS, Azure, DigitalOcean), server optimization, and complex database migrations. A natural problem solver and team lead, I bridge the gap between complex engineering requirements and flawless user experiences.
