Production Deployment, Ownership Transfer & System
⭐⭐⭐⭐⭐ 5 Stars
Hanzla helped me take full ownership of my SaaS platform and successfully completed a complex deployment, database migration, and integration project involving Stripe, Zoho CRM, MongoDB, and Vercel.
He was responsive, patient, and worked through issues as they were discovered during testing. Most importantly, I found Hanzla to be an honorable man who stayed committed to the project until everything was working properly.
Reliable developers with both technical skill and integrity are hard to find. I would gladly work with him again and would recommend him to anyone looking for a dependable developer. Steven Johnson - Owner of IUL Calculator Pro

Long-term Next.js Developer for Insurance Platform
Even though we are in different countries and have a basic different language, H persisted and did a fantastic job. I must admit I was hesitant to hire someone from a different country; but I made the right choice with Hanzla. I do highly recommend him. He went above and beyond to make sure everything met my needs.
