Great session going through n8n I learned a lot will certainly call upon Rajesh again

Rajesh is a pleasure to work with -- very accommodating, open to mentoring on calls and/or making contributions offline, and receptive to changes that inevitably come up "on the fly". Highly recommend!

Rajesh complete a job for me that involved creating a form in ASP.Net core that captured user information and a photo for upload to a SQL Server table for review. I especially appreciated his willingness to tweak the deliverable to ensure it met the requirements of the job.

My initial review for Rajesh was limited because he requested time to review the problem after my providing some details. That reflects his honesty - he is not charging while doing some research. Following this I hired Rajesh to implement PayPal for our organization. He returned the updated project with clear, functioning code on time. His communication during the development was excellent, allowing me to efficiently and effectively collaborate with him. In this session today he guided me in cutting over from Sandbox to Live account processing. I could not be happier and certainly will be working with Rajesh to solve future code challenges!

I operate at the intersection of proactive automation and reactive problem-solving, helping businesses build resilient AI systems and founders launch production-ready applications.

My work focuses on two primary areas:

As an Automation Architect: I partner with companies to act as a "catalyst for practical innovation". I design and deploy robust, AI-powered workflows that eliminate bottlenecks, letting teams focus on creativity and strategy by letting AI do the busywork.
As an AI Code Rescue Expert: I specialize in "MVP Hardening." I take promising but fragile AI-generated prototypes and refactor them for security, scalability, and performance. I turn 'vibe code' into viable, professional applications ready for real-world users.

My work aims to close the gap between AI's potential and its practical, impactful application in business.
