About this gig
Two weeks ago, ChatGPT also charged a client 3,200 API. Frontend Java Script would be hardcoded. OpenAI was called each time the page was refreshed.
I'm Hammad. I fix disasters like this and create AI integrations that will not cause you to run bankrupt.
I created VulnGuard AI - an AI scanner of smart contracts powered by Claude API. Scans 50+ contracts a day, at $0.08 a scan, rather than $2. It is not incidental but developed over time.
I have developed an on-the-fly transcribed interview assistant on AI. It is used by recruiters to make technical calls. Handles overflow of out of context 30 minute discussions.
By employing me you get:
- Chatbots that react to YOUR information due to AI, not delusions. I am engaged in RAG systems - the foundation of knowledge is your documents. AI cites sources. Even when it does not know what it tells her so, but instead, makes things up.
- In-built cost optimization. I keep queries that are common. Less costly models should be used in performing simple tasks. Batch API requests. Mean savings: 60-70 per month bills.
- Working error handling. API down? Rate limited? Timeout? All covered. Never introduce mystical error messages to your users.

Over the past 4 years, I've specialized in constructing robust SaaS applications and deploying real AI features into live production environments. I'm not referring to half-baked side projects; I'm talking about scalable platforms designed for growth. From architecting resilient backends to handling high concurrent users and delivering functional AI integrations, that's my wheelhouse.
Let's chat if you're serious about building something exceptional and want to see your plans hit production immediately.

FAQ
How much will AI API costs add to my monthly expenses?
It depends on usage, but here are real examples: Chatbot answering 500 questions/month: $10-20 RAG system with 50 documents answering 1,000 queries: $30-60 Content generator creating 200 blog posts: $40-80 I provide a cost calculator with delivery so you can estimate based on your traffic. I also
Can the AI hallucinate or give wrong answers?
Yes, all LLMs can hallucinate. I reduce this through: RAG (AI only uses your provided documents) Prompt engineering ("Say 'I don't know' if uncertain") Confidence scores (warn users when AI is guessing) Citation requirements (AI must cite sources) But 100% accuracy is impossible. For critical use c
What if OpenAI raises prices or shuts down?
I build with provider flexibility. Easy to switch between OpenAI, Anthropic, OpenRouter, or self-hosted models. Migration typically takes 1-2 hours. Premium package includes multi-provider setup by default.
Can you use my proprietary data without it leaking to OpenAI?
OpenAI's API has zero data retention for business tier ($20/month minimum). They don't train on your data. For absolute privacy, I can use self-hosted models (Llama 3) that never send data externally. Premium package includes this option.
Do I need to provide training data or do you source it?
You provide domain-specific data (your docs, policies, FAQs). I provide the integration. If you need help organizing/preparing data, I can do that as an add-on ($100-300 depending on volume).
