Saimul I.

I build production-ready websites, SaaS platforms, web apps, and AI-powered products for startup founders and growing businesses, using React, Next.js, Node.js, TypeScript, Tailwind CSS, Supabase, PostgreSQL, and MongoDB. Top Rated Plus, 10+ years of full-stack development, 250+ websites and web apps shipped. I have also built and run my own SaaS product, so I look at every project through two lenses: is it technically sound, and will it actually work as a business. I ask questions, challenge assumptions, and tell you when a simpler solution beats the one you came in with. WHAT I BUILD ✓ Websites: business websites, marketing websites, landing pages, and website redesigns built with Next.js, React, and Tailwind CSS, fast, responsive, and SEO-friendly ✓ CMS websites: WordPress, Strapi headless CMS, or a custom CMS, so your team can update content without a developer ✓ SaaS MVPs and full SaaS platforms: authentication, user roles, subscription billing, dashboards, admin panels, multi-tenant architecture ✓ AI integrations and AI agents: chatbots, AI knowledge bases, voice agents, LLM features using OpenAI, Claude, Gemini, Grok, Perplexity, OpenRouter, ElevenLabs, and Vapi ✓ Workflow automation: n8n, Make, and Zapier connected to your website, apps, CRM, and APIs ✓ B2B platforms, internal tools, and custom web applications ✓ E-commerce websites and real estate portals ✓ Codebase rescue: taking over existing websites and apps, fixing technical debt, improving speed and performance, and rebuilding for scale WHO I WORK BEST WITH ✓ Non-technical founders who need a technical partner they can trust ✓ Businesses that need a new website or a redesign that brings in leads and sales ✓ Startups that need an MVP built fast, with architecture that survives the next funding round ✓ Businesses whose website or product has outgrown its codebase ✓ Teams adding AI features or automation to an existing website or product ✓ Clients who were burned by a previous developer and need the project stabilized HOW I WORK ✓ Discovery first: we clarify goals, users, and scope before writing code ✓ Full ownership: architecture, UI, frontend, backend, APIs, database, deployment, and product strategy ✓ Clear milestones, regular updates, and no surprises mid-project ✓ Clean, documented, scalable code you fully own ✓ Post-launch support and optimization RESULTS CLIENTS HAVE REPORTED ✓ "Since the new platform launch, our online sales have skyrocketed by 300%!" ✓ "Seamless app and e-commerce integration, our revenue grew by over $2M!" ✓ "Our redesigned product won the Web Excellence Award for best UI/UX!" ✓ "Highly solution-oriented with deep skills across his field, a genuine problem solver." ✓ "Great listener who translates complex requirements into a product that actually works."

Yes. I build fast, mobile-friendly, SEO-ready websites with Next.js, React, and Tailwind CSS, from landing pages to large multi-page business sites. Which CMS do you use? It depends on your needs. WordPress for easy content editing, Strapi for a headless setup with Next.js, or a custom CMS when your content or workflow needs something specific. Can you build a SaaS MVP from scratch? Yes. I handle the full build, from planning and UI to backend, database, and deployment. Can you take over an existing project? Yes. I start with a code review, flag risks and technical debt, then stabilize and continue development. Do you work with non-technical founders? Yes, most of my clients are. I explain decisions in plain language and help shape the product, not just code it. Can you add AI to my existing website or app? Yes. I integrate LLMs, AI chatbots, AI agents, voice AI, and automation into existing websites and React, Next.js, and Node.js products.
