Looks like you have JavaScript disabled. For the full Twine experience, you will need to re-enable it.

I’m Javad Hashemi, a full-stack developer focused on building scalable, production-grade web systems. Over the past 5+ years, I’ve worked extensively with Node.js and NestJS, and I enjoy designing backend architecture that’s reliable under real-world load—using modern authentication/authorization patterns, background jobs, and event-driven workflows. I also bring strong full-stack product experience with Next.js (SSR), PostgreSQL/Prisma, Redis, and Docker, along with thoughtful observability using Prometheus, Grafana, OpenTelemetry, and Jaeger. Beyond web engineering, I delivered 500+ commercial algorithmic-trading projects and published 26 products on the MQL5 Marketplace, so I’m comfortable combining rigorous engineering with performance-focused problem solving.…I’m Javad Hashemi, a full-stack developer focused on building scalable, production-grade web systems.
