Project details
Turn your AI-generated, vibe-coded app into a production-ready product. I harden apps built with Lovable, Bolt.new, V0, Cursor, and Claude Code, cleaning up shortcuts, ensuring reliable payment processes, fortifying app security, and closing gaps so you can ship with confidence.
What I'll fortify:
• Auth: secure sessions, OAuth, roles/permissions, brute-force protection
• Backend APIs: input validation, rate-limiting, RBAC, error handling, logging
• Payments: safe transaction flows, webhooks, retries, idempotency
• Twilio & OTP: verified senders, delivery checks, replay prevention
• Email Delivery: SPF/DKIM/DMARC, bounce handling, templates, tracking
• Analytics: privacy-aware events, source attribution, dashboards
Deliverables include a risk report, fixes, and a clear checklist for ongoing maintenance. Milestone-based delivery available for larger scopes.

Back Migration help on GCP/Firebase
MA was an exceptional communicator and always provided plenty of detail for what he was working on and where he ran into issues. We gave him some complex problems and he was able to move them forward. I would be happy to work with him again in the future.

MVP Development - AI SaaS
MA delivered outstanding work for a complex project he built from scratch! He is extremely talented, efficient, and has a sharp eye for both technical execution and product logic. Throughout the project, he communicated clearly, met every deadline, and went above and beyond to ensure the final result exceeded expectations. Highly recommended, I’d work with him again in a heartbeat.

✅ I employ Agentic Development via Claude, Cursor, & Antigravity and deliver a week's work in a day.
✅ I'm fluent in english speaking & writing, I will come on Zoom/Meet without any problems or hesitations for demos & progress updates.
I have extensively worked with European clients (Netherlands, Spain, Latvia, and France) and built GDPR and HIPPA-complied apps including stunning.so (seed-funded) and bridge2people.com (bootstrapped). I have also refactored countless vibe-coded apps including maxout.ai and xeko.ai. I have also done migrations for platforms with huge active user bases in production, for example dadohr.com which is an HR automation platform based in US. So I have about 7 years of practical experience working with legacy code and huge technical debts in production apps.
Being the founder of grandeur.dev and have raised a quarter million dollars from Alchemist Accelerator and Hustle Fund, I have the knowledge and expertise to take an idea to a product that thousands of people love. Grandeur is an extremely ambitious project, AND MY BRAINCHILD and you can access it at console.grandeur.dev.
My bias is toward production reliability: clear error handling, logging, rate‑limits, and clean APIs that are easy to test and extend by later developers.
