About
Hire a Full-Stack Software Engineer
I'm Saffaullah Shuvo — a software engineer specializing in React, Next.js, TypeScript, and Node.js. I build AI-first web applications with real-world impact. Currently a core engineer at Themefisher, building CMS platforms used by developers and businesses worldwide.
What I Do
I'm a full-stack software engineer with over 3 years of hands-on experience building high-performance web applications. My specialization is React, Next.js, and TypeScript on the frontend, with Node.js and Go on the backend. I work with MongoDB and PostgreSQL for data, and I integrate AI-driven workflows throughout my development process.
As a core engineer at Themefisher, I own end-to-end development for the Sitepins CMS — from authentication systems and RESTful APIs to frontend architecture. I've built component libraries used in premium templates for developers and businesses globally.
My background in Applied Mathematics gives me a unique perspective on problem-solving and system design. I think in systems and draw in code — from CMS platforms to canvas rendering engines.
