Narayanganj, Bangladesh - 7:06 pm local time
I'm MD Saidul Islam, a Full-Stack Software Engineer with 5+ years of experience building production-grade web products using TypeScript, Next.js, and Node.js. I turn complex business requirements into scalable, secure, and pixel-perfect digital products.
What I specialize in:
SaaS MVP Development — Rapid prototyping and deployment using Next.js, Tailwind CSS, and Supabase, with full CI/CD pipelines on Vercel.
AI-Powered Web Applications — Custom OpenAI integrations, intelligent chat interfaces, and smart automation workflows built to scale.
Figma to Next.js Conversion — Pixel-perfect, mobile-first UIs that match your design system exactly.
SEO & Core Web Vitals Optimization — Server-side rendering (SSR), structured data markup, and sub-second page loads that rank.
Admin Dashboards & CRM Platforms — Role-based access control, dynamic data visualization, and secure REST APIs.
Tech stack:
Frontend: React.js, Next.js (SSR, SSG, ISR), TypeScript, Tailwind CSS, HTML5/CSS3
Backend: Node.js, Express.js, RESTful APIs, JWT Authentication
Database: MySQL, Supabase, Prisma ORM
AI & Automation: OpenAI API, custom AI chatbots, intelligent workflow design
DevOps: Vercel, Netlify, GitHub Actions, CI/CD
Why clients hire me over other developers:
✔ SEO-first architecture — every project is built with server-side rendering from day one, maximizing organic search visibility.
✔ Performance-focused — I target Core Web Vitals scores that put you ahead of 90% of competitors.
✔ Clean, maintainable code — documented, modular, and built to hand off without friction.
✔ Clear communication — weekly updates, fast response times, and proactive problem identification before they become blockers.
If you have a product idea, a Figma file, or a performance problem — let's talk. I'm ready to review your project scope and get started.
