Muhamad R.

Hi, I'm Risman, a Senior Full Stack Engineer with 12+ years of experience building SaaS products, web applications, and AI-powered solutions. I've worked with startups and growing companies to build products from MVP to production, improve existing systems, and solve complex technical challenges. My primary expertise is in Next.js, TypeScript, React, Golang, Python, and PostgreSQL. In recent years, I've focused heavily on AI application development, helping teams build AI-powered features using OpenAI, LangChain, LangGraph, and multi-agent architectures. My experience includes AI assistants, workflow automation, cognitive training platforms, and AI application builders. One of my most significant achievements was leading the migration of a complex diagramming platform from an SVG-based rendering engine to mxGraph. This modernization improved scalability, simplified future development, and enabled support for additional export formats and business requirements. I've contributed to multiple AI-focused products, including an AI application builder platform, a cognitive health platform powered by AI-generated exercises, and an open-source AI platform focused on prompt engineering and AI workflows. I enjoy working closely with founders and product teams to turn ideas into reliable software. My approach focuses on clean architecture, maintainable code, performance, and building systems that can scale as the business grows. Core technologies: • Next.js • React • TypeScript • Golang • Python • PostgreSQL • OpenAI APIs • LangChain • LangGraph • Supabase Whether you need help building a SaaS platform, integrating AI into your product, developing a complex dashboard, or improving an existing application, I can help deliver solutions that are reliable, scalable, and production-ready. I'm always happy to discuss new projects and technical challenges.
