Hello, I'm Shahriar Rofi, CEO of Nexa Core Digital Ltd. Transforming Ideas into Functional Web Applications.
Most developers build static websites. I engineer dynamic web applications that solve business problems. Whether you need a secure client portal, a custom SaaS dashboard, or a robust business management system, I provide the architectural expertise to make it happen.
As a full-stack expert specializing in the MERN stack and Next.js, I focus on building scalable, database-driven solutions that go beyond simple layouts.
What I Build Best:
Custom Portals: Secure login areas for law, health care, real estate, and recruitment.
SaaS MVPs: Rapidly developed functional products for startups.
Admin Dashboards: Complex data management systems.
Inventory/Utility Tools: Like QR-based systems and audio processing tools.
My Tech Stack:
Frontend: React.js, Next.js, Tailwind CSS.
Backend: Node.js, Express, Firebase/Supabase.
Database: MongoDB, PostgreSQL.
Why Nexa Core? We don't just "design" pages; we build logic. We ensure your application is fast, secure, and ready to scale.
Let's build a system that works for your business. Message me to discuss your project!

Enfield, United Kingdom - 12:13 am local time
Looking to turn complex ideas into AI-driven, scalable digital products or looking to launch a high-impact MVP or scale a complex digital product??
My tech journey is fuelled by technical excellence. While pursuing my law degree, I became fascinated by the intersection of high-end web design and complex web architecture.
After years as a UX researcher and project manager, I founded Nexa Core Digital Ltd.
With a background in law and technology, I bring a unique analytical rigour to digital product strategy. I lead a team of senior engineers and designers at Nexa Core Digital 𝐋𝐭𝐝—a London-based, full-service digital agency and software company helping startups and growth-stage brands craft intelligent, user-first experiences.
💡 Expertise: Intelligent Product Architecture

AI & LLM Integration: Building custom AI Agents, RAG-based systems, and integrating LLMs (OpenAI, Claude, Llama) to automate workflows and enhance product intelligence.
Analytical UX Research: Leveraging my legal training to engineer logical user journeys for high-stakes industries like Legal tech, EdTech, Healthcare, retail, e-commerce, SaaS & B2B.
Engineering Excellence: Delivering production-ready systems using a professional React/Next.js and Tailwind CSS frontend sequence.
