Senior Fullstack Engineer

I’m a senior full-stack engineer with over 15 years of experience building scalable web applications, backend systems, and high-traffic platforms across Europe and North America. My background spans PHP, Python (Flask), Node.js, Laravel, React, Vue.js, and microservices architecture, with hands-on work in AWS environments, data-heavy systems, automation, and platform engineering.

Across roles at Citrix, PwC, Perk.com, Poornam Infovision, Vanilla Networks, and most recently Byborg Enterprises, I’ve worked on everything from large-scale global video streaming platforms to release automation systems, marketing platforms, reporting engines, and modern microservice ecosystems. I enjoy solving complex architecture problems, improving performance, modernizing legacy systems, and collaborating across teams to deliver polished, reliable products.

Right now, I’m exploring opportunities as a Senior or Staff Software Engineer, ideally on teams building high-impact products with strong engineering culture. I’m especially interested in roles involving full-stack development, backend architecture, platform engineering, system design, or modernization of large systems.
