You will get Integrate ChatGPT or Claude API into your existing web app


Project details
You have a web app and want AI features in it — but you don't want
to learn the OpenAI or Claude APIs yourself, and you don't want a
hacked-together proof of concept that breaks in production.
I integrate AI into existing apps cleanly. Senior engineer, 8 years
full-stack, last 2 focused on AI integration for SaaS founders and
product teams.
Most freelancers will give you a working demo. I give you a
production-ready integration: error handling, retries, rate limiting,
token cost tracking, secure key management, tests, and documentation
your team can actually maintain after I leave.
I work with Node.js, Laravel, Django, Go, and Python backends.
React, Next.js, and Vue frontends. I send Loom updates every Friday
so you always know where things stand. I respond within 4 hours
during business hours.
If you're not sure whether your project fits a tier, send a message
first — I'll tell you honestly which tier matches your scope, or
whether you need custom work.

About Sulaman
I Build AI Features Into Your SaaS - RAG, Agents & Chatbots That Ship
Lahore City, Pakistan - 3:35 pm local time
I've been building software for 8 years. The last 2 have been mostly
AI work — adding ChatGPT and Claude features into existing SaaS
products, building chatbots that actually use a company's own data,
and writing agents that automate workflows founders are sick of doing
manually.
Most of my AI clients come to me with the same problem: they tried
adding AI themselves, or hired someone cheap, and the result was
either a generic chatbot that hallucinates or a half-finished proof
of concept nobody can deploy. I clean those up, or I build the thing
from scratch the right way.
Here's what I usually build:
- Chatbots trained on your own docs, FAQs, or database (RAG with
Pinecone, Weaviate, or pgvector)
- AI agents that handle real workflows — reading emails, updating
your CRM, posting to Slack, etc.
- OpenAI and Claude API integrations into Node.js, Laravel, Django,
or Go backends
- Custom internal tools where AI does the boring work (summaries,
classification, drafting)
- Cost optimization on existing AI features (most teams burn 3-5x
more on tokens than they need to)
My background is full-stack, so I don't just bolt AI on top — I make
sure it fits properly into your codebase, has tests, and your team
can maintain it after I leave.
Stack I work in daily:
Backend: Node.js (Nest, Express), Go, Laravel, Python
AI: OpenAI, Claude, LangChain, LlamaIndex, vector DBs
Frontend: React, Next.js, TypeScript
Infra: AWS, Docker, GitHub Actions, Vercel
A few things about how I work:
I'll tell you when an idea is bad. I've talked clients out of features
that would have wasted weeks. That's part of the job.
I send a Loom walkthrough every Friday so you always know where
things stand. No "still working on it" updates.
I respond within 4 hours during business hours. My timezone overlaps
with US East Coast mornings and full European working hours.
I take fixed-scope projects or longer retainers. Not a fit for 5-hour
"quick fix" jobs.
If you have a project in mind, send a brief or a Loom — I'll reply
within 4 hours and tell you honestly whether I'm the right person
for it.
