What I'm looking for

I seek a senior role building scalable SaaS or eCommerce platforms where I can lead engineering teams, optimize performance, integrate APIs/payments, and drive CI/CD and test-driven delivery in a collaborative, growth-oriented company.

I am a Full Stack Web Developer with over six years of experience building scalable CRM systems, social networks, and eCommerce platforms, having delivered more than 20 projects across startups and enterprise environments. I have a track record of improving performance—reducing load times by up to 65%—and implementing secure authentication (OAuth, JWT) and payment integrations.

Technically, I work across React, Next.js, Node.js, PHP, SQL databases and cloud hosting (AWS, GCP), and I lead engineering teams to ship reliable, test-driven software using CI/CD and containerization. I enjoy optimizing architectures, mentoring engineers, and building user-focused SaaS products that scale.
