You will get an AI Feature to Your SaaS in 2 Weeks

Project details
You will get a working AI feature added directly to your SaaS product, not a standalone demo, but something integrated into your actual codebase and ready for real users.
I focus on AI integration for SaaS teams: designing the prompt logic, connecting to OpenAI or Claude, and making sure the feature holds up under real usage, not just the happy path. I've built AI pipelines for production products, including my own tools like PromptCritic (prompt analysis) and AgentForge (multi-agent AI simulation), both public and reviewable.
You'll get clean, documented code, a short handoff explaining how it works, and a feature you can maintain or extend later — without needing to hire a separate AI engineer.

Hasnaat is a skilled, polite, and responsive professional whom I'd definitely recommend working with. Unfortunately, we were unable to move forward with the project at this time due to technical reasons, but I will definitely consider his services for future work.

Hasnaat did a great job! He was able to quickly understand the requirements and turned around with changes in two days. Very professional, would highly recommend.

★ THIS WORKS IF YOU'RE THINKING:
─────────────────────────────────────────────────
"I need a full-stack engineer who understands product, not just tickets"
"My frontend works but the codebase is becoming unmaintainable"
"I want AI features but don't know where to actually start"
"I need async, independent work with clear communication"
─────────────────────────────────────────────────
✗ THIS DOESN'T WORK IF YOU:
─────────────────────────────────────────────────
✗ Need someone available 24/7 and responding within minutes
✗ Want to redesign the scope three times before committing
✗ Are optimizing purely for the cheapest rate on the platform

Steps for completing your project
After purchasing the project, send requirements so Hasnaat can start the project.
Delivery time starts when Hasnaat receives requirements from you.
Hasnaat works on your project following the steps below.
Revisions may occur after the delivery date.
Scope & Requirements
We confirm exactly what the AI feature should do, what data it'll work with, and how it fits into your existing app.
Prompt & Pipeline Design
I design the prompt logic and AI pipeline structure before writing integration code, so the approach is solid from the start.
