If your back-end is becoming slow, unstable under load, or difficult to scale, I help fix exactly that. I specialize in building and optimizing Laravel and Node.js backend systems for SaaS platforms, marketplaces, and API-heavy products where performance and architecture directly impact revenue and user experience. Over the last 10+ years, I’ve worked on production systems including B2B logistics marketplaces, multi-vendor eCommerce platforms, and large-scale API infrastructures with real-world scaling challenges. My focus is not just development: I work on system design, performance tuning, database optimization, and AWS-based deployment stability. I typically step in when systems need to move from “working” → to “reliable, scalable, and production-grade under real load.

That means I think through architecture before writing a line, optimize for performance from day one, and deliver systems you won't need to rebuild in 6 months.
