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.

1. 𝗔𝗜-𝗻𝗮𝘁𝗶𝘃𝗲 𝗠𝗩𝗣𝘀 & 𝗦𝗮𝗮𝗦 (𝗜𝗱𝗲𝗮 → 𝗪𝗼𝗿𝗸𝗶𝗻𝗴 𝗣𝗿𝗼𝗱𝘂𝗰𝘁)
If you're a founder looking to turn an idea into a working product in 3–4 weeks:
I build AI-native applications using React / Node / FastAPI + OpenAI / Anthropic + Supabase.
2. 𝗠𝗶𝗱𝗱𝗹𝗲𝘄𝗮𝗿𝗲, 𝗔𝗜 𝗮𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 & 𝗶𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻𝘀
If your systems don’t talk to each other (Custom apps, Shopify, CRMs, APIs):
I design and build middleware layers, AI automation workflows (n8n or make), AI agents and integrations that actually hold up in production.
3. 𝗙𝘂𝗹𝗹-𝘀𝘁𝗮𝗰𝗸 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 (𝘁𝗲𝗮𝗺 𝗲𝘅𝘁𝗲𝗻𝘀𝗶𝗼𝗻)
If your product already exists but needs reliable execution:
I integrate into your workflow and take ownership of backend systems, APIs, dashboards, and feature delivery without constant oversight.
