I had the pleasure of supervising Chirag Menariya during an intensive 8-week applied AI internship under my leadership. The project involved integrating ChatGPT and WhatsApp APIs into a secure, modular trade relay system—requiring both technical discipline and architectural foresight. Chirag approached this challenge with calm focus, delivering clean, well-structured code and adapting quickly to shifting parameters with minimal oversight.
What stood out most was his ability to work from abstract technical briefs and turn them into functioning modules, showing initiative and sound judgement. His methodical approach made him easy to trust with critical system components, and his output consistently met the standard I expect from contributors on high-impact AI projects.
Any organisation building future-focused, AI-integrated systems would benefit from having Chirag on their team. I’d be happy to work with him again.

I had the pleasure of working with Chirag at Perihelion Ventures, where I served as Project Manager and he worked on cybersecurity for the platform.
Chirag is exceptionally creative and resourceful, with deep knowledge and hands-on experience across a wide range of computer science and IT disciplines. With minimal direction, he designed and built a database architecture that was both secure and highly scalable, laying a strong foundation for future growth.
He was also invaluable in assisting with building out and debugging the platform’s code, consistently demonstrating strong problem-solving skills and an ability to untangle complex technical challenges.
In addition, Chirag went out of his way to support the broader team, offering thoughtful recommendations on tools, methods, and approaches to help others overcome obstacles in their own work.
Beyond his technical talent, he is personable, collaborative, and a pleasure to work with. I have no doubt he will be an asset to any team, and I wish him every success in his future endeavors.
