Saimul I.

Full Stack Developer | Building SaaS, MVPs & Shopify Solutions

You're probably wondering, among thousands of Top Rated Plus freelancers, what makes this one any different. And honestly? Skill-wise, not much. Every Top Rated Plus developer on this platform is in the top 3% of Upwork. We've all shipped production-grade products, debugged at 2am, and argued about the right way to structure a database schema. That's just the baseline. Where I'm different is how I show up. I don't take a brief and disappear into a code editor. I ask questions. I challenge assumptions. I push back when something doesn't make business sense, and I'll tell you when a simpler solution beats the one you came in with. I've built and run my own SaaS products, and I come from a business background, so I see every project through two lenses at once: what you're building technically, and whether it's actually going to work as a business. Most developers will build exactly what you ask for. I'll build what you actually need. That means you get a co-builder, not a contractor, someone who's genuinely invested in the outcome, brings a bit of humor to the process, and won't let you spend six figures heading in the wrong direction. If that's the kind of working relationship you've been looking for, keep reading. My core stack: React / Next.js, Node.js, TypeScript, Supabase / PostgreSQL, MySql MongoDB, Mongoose, Prisma, Rest API, GraphQL AI Integrations: OpenAI, Claude, Open Router, Grok, Gemini, Perplexity, Eleven Labs, Vapi, and AI Agents Automation: n8n, make, and zapier. 🌟 Here's what founders I've built for are actually saying: ● "Since the new platform launch, our online sales have skyrocketed by 300%!" ● "Customer sign-ups and engagement magnified after the rebuild!" ● "Seamless app and e-commerce integration, our revenue grew by over $2M!" ● "Our redesigned product won the Web Excellence Award for best UI/UX!" 10+ years of full-stack development. $10M+ in client revenue powered by platforms I've shipped: SaaS products, web apps, e-commerce engines, real estate portals, and AI-powered platforms across B2B and B2C. *** ⚡ We're probably a great fit if you're thinking: ● "I have a huge market opportunity and need the best engineer to capture it" ● "My product vision has grown, but the codebase hasn't caught up" ● "I know the business side, I need a technical co-builder I can actually trust" ● "I'm not a developer and can't afford to waste months on the wrong hire" ● "My last dev burned me badly, I won't let that happen again" ● "I need a scalable, production-grade platform built to grow with me" *** What you get when we work together: ★ Full ownership: Architecture, Frontend, Backend, APIs, Deployment, and Product Strategy, handled ★ A production-ready platform your users love and your investors respect ★ Technical debt and architectural mistakes caught before they become expensive ★ A turnkey, scalable codebase built to survive your next funding round ★ Clear communication, on-budget delivery, and no surprises mid-project ★ Core architecture you can reuse across future product lines, cutting long-term dev costs significantly *** What my clients say: ✅ "Saimul does incredible work! Super passionate, consistently went above and beyond every single time." ✅ "Communication was always smooth, very proactive and easy to reach throughout the entire project." ✅ "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." ✅ "Excellent work, sharp attention to detail, and always willing to go the extra mile for the team." *** I specialize in serious product builds, SaaS MVPs, B2B platforms, AI integrations, e-commerce systems, and complex full-stack applications. No template flips. No shortcuts. I've shipped 150+ websites and web apps across a decade of development. As an engineer and technical architect, I have a 360° view of the full build lifecycle, from discovery and wireframing through production deployment and post-launch optimization. My capacity is limited. I carry 80% repeat clients and 40% referrals, and I only take on projects I'm certain I can execute at the highest level. What I look for in a new client: ● A clear product vision with room to collaborate ● Values clean architecture and long-term thinking over shortcuts ● Focused on real user outcomes, not just shipping pixels ● Knows the scale they're building toward Not the right fit if: ✗ You need a $300 template site, that's not what I build ✗ You want to micromanage architecture decisions and sprint cycles ✗ Honest communication and mutual respect aren't priorities *** Sound like a fit? 📋 Review my portfolio and live project examples on this profile 💬 Hit "Invite" or "Message" and send me a short note about your project, I respond within hours.
