What clients say

I attended one of Haojun’s courses and found it to be a very insightful and valuable learning experience. The course provided me with new perspectives on AI and how it can be applied effectively in our work and business. I truly appreciate Haojun’s willingness to share his knowledge, experience, and practical insights throughout the training. Thank you, Haojun, for your generosity in sharing and for making the learning journey meaningful. I would highly recommend his course to anyone who wants to deepen their understanding of AI.

I met Hao Jun at a course on Gen AI as part of my company training. He was extremely friendly and making conversation with everybody, myself included. As I got to know him, I found out that he does website design and creation as a full time job, and casually asked him more about the whole process of creating a website, as I was also in the midst of creating a website for my own business, albeit struggling to do so as I had no experience with anything website related. Upon hearing that, Hao Jun not only asked to look at it, he even offered to help me with my process and basically did up my entire site for me in just a couple hours for free(!!), despite it taking me weeks without even doing half as much as he did! Not only that, he designed the site to the exact vision and idea that I had. I could not have been more satisfied! I am extremely grateful for his help, else I would be still struggling to complete my website. The combination of speed, quality and professionalism is unparalleled and I'm honestly floored that he was so kind to do so. I will definitely be engaging his services in the future for further website design, as well as the maintenance of my site and any related services. Thank you Hao Jun! 😁

It’s been a great journey working with HaoJun. He’s incredibly knowledgeable in his field and always goes the extra mile, taking the time to explain in depth how the AI integrations and solutions actually work rather than just delivering a black box. What stood out most was his patience, he never rushed through explanations, even when questions came up repeatedly, and always made sure we truly understood before moving forward. His combination of technical expertise and genuine willingness to teach made the whole experience smooth and reassuring. I’d highly recommend HaoJun to anyone looking for a partner or solution vendor who’s both skilled and easy to work with. It was also a smooth and great collaboration with him.

I attended Haojun's 1 day claude coding masterclass and was able to self host and spin out my company's website and internal tooling. Highly effective methodology combined with personalized assistance that opened many possibilities of what would have taken weeks and months of time and lots of money to achieve with custom software.

We have worked with Haojun for over a year. Haojun has taken the time to understand our business and workflow and see where he can use AI to streamline operations. I can’t speak highly enough of him. He is patient, passionate about AI and quick to respond to our queries. He has not only improved our workflow, he also conducts training to ensure we are up to date with the latest developments. AI can be intimidating. You cannot have a better person to guide you in the process of learning about, adapting to, and incorporating AI into your business.

Haojun and On The Ground have been exceptional in making AI practical, accessible, and genuinely impactful. What stands out is their ability to simplify complex technology into real-world solutions that drive productivity, transformation, and growth. Professional, innovative, and deeply committed! Haojun doesn’t just talk about AI, he helps people and businesses truly build with it. Highly recommended for any organisation serious about meaningful AI adoption.

Working with Haojun was an absolute game-changer for our legal operations. He successfully developed and launched three critical systems for us: a comprehensive Finance Reporting portal, an automated Time Monitoring solution, and a fully integrated HR (+claims) Portal and Mobile App. His deep technical expertise and experience collaborating with the legal industry in AI integration made complex workflows completely seamless. Haojun deeply understood our business challenges and operations and built highly intuitive, scalable tools that have significantly helped us. Communication was fantastic - he was always very responsive even when out of town, deadlines were always met, and the final products exceeded our expectations. May i add that he is also a very patient man to work with! I highly recommend him to anyone looking to leverage cutting-edge AI and software development to scale their business.

Haojun has been tremendously helpful in helping us scale during this current AI era. If there is a hidden gem in this domain and industry, he is it. We originally came looking for an AI expert to help us set up some processes and build foundational knowledge. By the end, he single-handedly trained our team and built an entirely new business vertical for us at a tiny fraction of market costs. It's almost incredible to find someone so ethical, knowledgeable, and genuinely generous with their input and time. I seriously suggest that anyone truly looking to train their teams or leverage AI to scale their business reach out and connect with him.
