Experienced and proven Fullstack Developer (Next.js + Supabase) needed
Working with Rumman was an excellent experience from start to finish. He is a highly skilled and experienced full-stack developer who consistently delivered high-quality work throughout the project. His technical expertise, problem-solving ability, and attention to detail were evident in every aspect of the web application development process.
Communication was clear, timely, and professional, and he was proactive in providing updates and suggesting improvements that enhanced the final product. He completed tasks efficiently, met deadlines, and demonstrated a strong understanding of both frontend and backend development.
I am very satisfied with the outcome and would not hesitate to work with him again on future projects. I highly recommend him to anyone looking for a reliable, knowledgeable, and proven full-stack developer.

Senior Cloud/DevOps Engineer for Zero-Trust Infrastructure Build (Next.js/Supabase/Vercel)
Rumman delivered good quality work on our AWS infrastructure setup. He is technically proficient, organized, and provided exceptional documentation, including detailed SOPs and verification videos that made the handover process smooth. While the project took slightly longer than originally anticipated to reach the final milestone, the quality of the end result was worth the extra time. I appreciated his professional communication throughout and would recommend him for complex DevOps and infrastructure tasks.

They need someone who can help them make good technical decisions, move quickly, and avoid expensive mistakes that slow a product down later.
That's the role I usually play.
Over the last 8+ years, I've helped startups and SaaS companies build products from scratch, launch MVPs, scale existing platforms, and bring AI features into products that already have real users.
I've worked on more than 125+ web applications, SaaS platforms, internal tools, customer portals, and AI-powered products across different industries.
My focus is not just writing code.
It's helping teams figure out what should be built now, what can wait, and how to keep the product moving without creating problems six months down the road.

• 8+ years of hands-on development experience
• 125+ products delivered across SaaS, AI, web applications, and internal platforms
• Consistent 5-star feedback and long-term client relationships
• Many clients come back for additional projects after the first engagement
• Strong product and engineering mindset
• Experience building both traditional SaaS products and AI-powered applications
• Clean, scalable, production-ready code
• Clear communication and dependable delivery
I use tools like Cursor AI, Claude Code, and GitHub Copilot to move faster, but I still believe good software comes from good engineering decisions, clean architecture, and understanding the business problem behind the product.
Some clients come to me with a complete specification.
Others come with nothing more than an idea and a rough direction.
I'm comfortable with both.
If you're building a SaaS product, AI application, internal platform, automation system, or MVP and need someone who can contribute beyond individual development tasks, feel free to send me a message 💬.
I'd be happy to hear what you're working on.
