I’m Jonny Ha, a Senior Full-Stack and Automation Engineer with over 10 years of experience building scalable web applications, backend systems, AI-powered workflows, and business automation platforms. I’ve worked with startups, growing businesses, and enterprise teams to develop reliable, production-ready solutions that improve operations, performance, and user experience. I enjoy turning complex ideas into clean, efficient systems that are built for long-term growth. My expertise covers both frontend and backend development, allowing me to handle projects from architecture and development to deployment and optimization. I work with modern technologies including React, Next.js, Node.js, TypeScript, Python, PHP, Laravel, MongoDB, PostgreSQL, AWS, Docker, and cloud infrastructure. I also have strong experience building APIs, integrating third-party services, and developing secure, scalable systems that support real business needs. In addition to software development, I specialize in automation engineering and AI integrations. I build intelligent workflows, webhook-based systems, internal management tools, and automation pipelines that reduce manual work and improve efficiency. I focus on creating practical solutions that help businesses operate faster, smarter, and more effectively while maintaining clean architecture and maintainable code. I value professionalism, clear communication, and reliable delivery throughout every project. Clients appreciate that I combine strong technical skills with practical problem-solving and a business-focused mindset. I’m comfortable working independently or collaboratively within teams, and my timezone is flexible to support smooth communication and collaboration with clients worldwide.
