Kazi Shariful Islam
Full Stack Developer &
Systems Architect
I engineer performant web architectures using Next.js and React paired with robust, modular backend systems in NestJS, Node.js, and Python (FastAPI). Focused on pristine UX, clean API designs, and scalable relational databases.
Edge Gateway (SSR)
Designing modular frontend structures and high-performance server microservices.
Powering multi-tenant administrative portals, custom dashboards, and real-time backends.
Maximized via server-side caching, localized state hydration, and asset budget optimizations.
Minimized network latency by fine-tuning stale state queries and persistent cache rules.
