Your app slows down under real traffic, the queue backs up, or a realtime feature falls apart at scale - that's the work I take. Backend engineer in PHP/Go for high-load SaaS, fintech and data-heavy platforms. What I've shipped: - Realtime engine in Go - Crypto trading platform - SEO analytics platform - Subscription streaming product - Service marketplace - Offline-first PWA - Admin panels and internal tools I genuinely enjoy what I do. The most valuable motivation for me is feedback from clients and end users. When I see that the product I’ve worked on actually helps people or makes them happy, it inspires me to keep improving and do even better.
