Project details
Stuck with a Lovable or Replit prototype that can’t connect to Stripe, Twilio, or OpenAI? We specialize in:
✅ Rescuing AI-Built MVPs: Fix broken API integrations (payment, auth, SMS, etc.) in your existing Lovable/Replit app.
✅ Cost Optimization: Slash AI API bills by 30–70% with caching, model switching (e.g., GPT-4 → Claude Haiku), and rate limiting .
✅ Scalable Backends: Migrate fragile Replit DBs to Node.js/Supabase with proper error handling.
Recent Example:
• Fixed a Replit-built telehealth app’s Twilio integration (messages failed 40% of the time) and cut API costs by 50% using LiteLLM.
What’s Included:
1. API Audit: Diagnose failures, latency, and security gaps.
2. Integration Overhaul: Rebuild connections with retry logic and monitoring.
3. Documentation: Handoff with a clean API spec for future devs.
Ideal For:
• Founders who used Lovable/Replit but hit walls with production-ready APIs.
• Apps needing HIPAA/GDPR-compliant integrations (we manually vet third parties).
Delivery Time: 2–4 weeks

Full-Stack WordPress Developer for a Rental Startup Website
It’s been a great experience working with this team. They went far beyond WordPress theme edits, providing full-stack development support for us with innovative solutions and r&d work for our multi-site domains — including frontend, backend, and server-level enhancements. Highly reliable, communicative, and proactive throughout the engagement. I’d happily work with them again.

Job Success
Lahore, Pakistan - 3:49 pm local time
Whether you're a founder trying to turn an idea into a live product, take a rough MVP to production, an operator whose team needs AI agents and workflows to eliminate manual busywork, or an engineering lead facing a backlog of broken integrations... you don't need another developer who just takes tickets. You need a senior product developer who thinks like a PM and owns the outcome.
Over 13 years and 4,000+ hours of production code on Upwork, I've maintained a 100% Job Success Score (JSS). Because I operate with lean overhead, I am able to offer senior-tier architectural execution at a fraction of agency costs... giving you elite product development with an unbeatable ROI.
𝗛𝗼𝘄 𝗜 𝗛𝗲𝗹𝗽 𝗬𝗼𝘂 𝗪𝗶𝗻:
AI-Native SaaS & Products: Turning complex concepts into live, secure, scalable web applications in 3-4 weeks using React, Next.js, Python/FastAPI, and Supabase.
Autonomous AI Agents & Workflows: Building resilient multi-agent architectures and complex integrations using n8n, Make, LangChain/LangGraph, and custom MCP setups that connect your LLMs directly to CRMs or Shopify.
Platform Rescue & Backend Scaling: Auditing and stabilizing fragile codebases. I take full ownership of backend APIs (Node.js/Python), cloud infra (AWS/Vercel), and database optimization (PostgreSQL/Prisma).
