About Simon

I’m a Full Stack and AI Developer with 7+ years of experience building reliable web, mobile, SaaS, and healthcare products. I work with Python, FastAPI, Django, Node.js, React, Next.js, TypeScript, AWS, PostgreSQL, Docker, and modern AI tools such as OpenAI, Claude, Gemini, LangChain, and LangGraph.

I can help with Generative AI features, AI agents, RAG systems, workflow automation, secure APIs, dashboards, multi-tenant SaaS platforms, and HIPAA or GDPR-compliant healthcare solutions. I have worked on products used by thousands of users, including healthcare platforms, fitness applications, business automation tools, and AI-powered systems.

I like to understand the real business problem before writing code. My focus is always on clean architecture, stable performance, security, and software that is easy to maintain as the product grows. I communicate clearly, take ownership of my work, and stay involved from planning and development through testing, deployment, and production support.
