Final Phase: Secure and Operation-Ready Website Audit

⭐⭐⭐⭐⭐ Outstanding developer – HIGHLY RECOMMENDED. I cannot recommend Sajat highly enough. This has genuinely been the best experience I've had working with a developer. Our project involved Stripe, Supabase, Resend, Vercel, GA4, secure digital fulfilment, private EPUB storage, signed downloads, webhooks and production deployment. Throughout the entire project, Sajat was professional, patient, highly skilled and incredibly thorough. What impressed me most was his approach. He didn't just complete tasks, he thought ahead, identified potential issues, documented everything properly and built clean, secure, scalable solutions. His communication was excellent from start to finish, and every question I asked was answered clearly and respectfully. The final system works beautifully. Payments, fulfilment, email delivery, analytics and secure downloads all integrate seamlessly. His attention to detail and commitment to quality gave me complete confidence in the finished product. He also produced one of the best handover documents I've ever received, making future maintenance straightforward. Beyond his technical ability, Sajat is simply a pleasure to work with, honest, reliable, patient and genuinely invested in delivering great work. I will absolutely be working with him again and he'll be the first developer I contact for future projects. Thank you, Sajat. It has been an honour working with you, and I wish you every success in both your career and personal life.
