You will get Your fixed Lovable, Cursor or Bolt MVP and ship it to production
Top Rated
Project details
š Built your MVP in Lovable, Cursor, Bolt, or v0?
And hit the wall where it works for demo but breaks for real users?
That's exactly what I do ā take AI-generated codebases and bring them to production-grade. Proper architecture, real authentication, secure payments, deployment that doesn't break, and the edge cases AI tools always miss.
Common problems I fix:
ā Auth that "works" but has security holes
ā Architecture that won't scale past 50 users
ā Hidden bugs in state management
ā Deployment failing in real Firebase/Supabase environment
ā Missing error handling and edge cases
ā Payment integration that's "almost done"
ā Database schema needing restructure before launch
What sets me apart:
ā 10+ years full-stack engineering (Angular, Node.js, Firebase, AWS)
ā Shipped 20+ production apps with real users
ā 100% Job Success on Upwork, $500K+ delivered through WhyNet
ā Backed by senior team ā code review on every project
I understand AI-generated code patterns (their strengths and blind spots). I don't rewrite for the sake of rewriting ā I fix what's broken and add what's missing.
Send your repo + a sentence about what's blocking launch ā tactical plan in 24h.

Wrap an existing PHP/MySQLi web app and publish it on the Apple App Store
Dmitry was clear and helpful all the way through the process and the work was completed to budget and well within the deadline. I'd certainly recommend him, and I'm looking to continue to use him for further updates to this app.

Job Success
Kiev, UkraineĀ - 4:12 am local time
I'm Dmitry, an AI Engineer with 10+ years of full-stack background.
I help SaaS, crypto, and digital product companies ship AI features that work with real users - at scale, within token budgets, with proper fallbacks.
The difference matters. Anyone can call the OpenAI API in a tutorial.
The hard part is making AI features that don't break in production: conversation memory that persists, prompts that survive edge cases, streaming that handles network drops, and costs that don't spiral.
That's what I do.
āāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāā
šÆ What clients hire me for
ā Custom ChatGPT / GPT-4o / Claude integrations into existing apps
ā RAG systems with vector search over business documents
ā AI chatbots & assistants with persistent context (web + mobile)
ā AI workflow automation (n8n + LLM for ops)
ā Token cost optimization & prompt engineering
ā Taking AI-built MVPs (Lovable, Cursor, Bolt) to production-grade
āāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāā

Delivery time starts when Dmitry receives requirements from you.
Dmitry works on your project following the steps below.
Revisions may occur after the delivery date.
Initial Code Audit (within 48h)
I review your codebase, identify what's broken, what's risky, and what's missing. You receive a written audit report with prioritized issues and a tactical plan within 48 hours of getting repo access.
Architecture Refactor
Restructure code to follow production patterns: proper folder structure, separation of concerns, type safety, environment configs. Database schema reviewed and restructured if needed. State management cleaned up.
