Shahzad A.

If you’re stuck with architecture decisions, scaling issues, or modern Node/Next.js challenges, I can help you move forward quickly and confidently.

I’m a Senior Full-Stack Engineer with 17+ years of professional experience, helping startups, founders, and engineering teams design, build, and scale reliable web applications.

I’ve delivered production-grade systems including e-commerce platforms, SaaS products, content management systems, real-time dashboards, and internal tooling. My recent work focuses heavily on NestJS backends, Next.js applications, and AI-driven automation using n8n.

I’ve worked across healthcare, quick commerce, and service-based platforms, often stepping in to:

• Review and improve existing architectures
• Fix performance and scalability bottlenecks
• Guide teams on best practices and clean code
• Help founders make the right technical decisions early

I communicate clearly, ask the right questions, and focus on practical solutions—not overengineering.
