Project details
You will get a working AI-powered SaaS MVP — not a demo, not a slide deck, but a real multi-tenant web app with authentication, a working database, and one core AI feature wired into OpenAI or LangChain. I've built this exact category of software before: an AI-powered preschool management platform and an AI-driven news intelligence platform, both shipped with real users and real data behind them. I focus on getting you something you can actually put in front of investors or early users, not just code that runs locally. You'll get clean, documented APIs so you (or another developer) can keep building after delivery, and a short handoff call so you understand exactly how it works.

Job Success
Gojra, Pakistan - 12:53 am local time
I build production-ready applications with React, Next.js, Node.js, NestJS, Python, FastAPI, OpenAI, LangChain, and RAG from scalable backend architecture and third-party integrations to AI workflows that solve real business problems.
I use modern AI development tools and coding agents to accelerate development, debugging, testing, documentation, and research while keeping architecture, code quality, security, and production reliability under control.
I don’t just connect an LLM to an existing app and call it “AI.” I focus on building AI features that work reliably with real users, real data, and real production constraints.
What I’ve built
AI Voice Automation Platform — PropTech
* Built an AI-powered voice automation system for apartment leasing
* Real-time speech processing with Twilio, Node.js, NestJS, and OpenAI
* LLM-based call scoring and semantic search across call history
* Improved call answer rate from roughly 50% to 95%
* Platform has contributed approximately $1M in business revenue
Production Admin Platform — Medical Technology
* Built and maintained a high-traffic platform for an FDA-cleared medical device ecosystem
* React + Node.js + PostgreSQL architecture
* Automated workflows across super admin, sub-admin, and patient roles
* Built for production-scale reliability and maintainability
* Product capabilities were cited by investors during the company's $5M funding round
AI Legal Intake & Document Processing
* Built an AI-assisted legal intake workflow to reduce manual data entry
* Automated OCR, document processing, data extraction, and workflow automation
* Turned document-heavy manual processes into structured, usable application data
Legal Operations Integrations
* Built a two-way integration between HubSpot, Litify, and Filevine
* Implemented field mapping, webhooks, synchronization logic, duplicate handling, and error recovery
* Synced 1,000+ records
* Saved the team 10+ hours per week
* Reduced manual data entry by 90%+
* Reduced duplicate/data-entry errors by 95%+
* Replaced hours-to-days-long manual updates with near real-time synchronization

How I approach projects
Before writing code, I look at where the system is likely to break data model limitations, API dependencies, scalability, failure handling, background processing, AI reliability, and integration edge cases.
I use AI tools to move faster, but I don't outsource engineering judgment to them. I review architecture, validate generated code, write tests, handle edge cases, and make sure the final system is maintainable by a real engineering team.
Whether you're:
* Building a new AI-powered SaaS product
* Adding OpenAI, Claude, Gemini, RAG, or AI agents to an existing application
* Developing a scalable React/Next.js + Node.js application
* Building complex API or CRM integrations
* Automating document-heavy workflows
* Implementing AI-powered search or knowledge bases
* Debugging or scaling an existing production system
Tell me what you're building, what isn't working, or where you're stuck. I'll give you a straightforward technical assessment and a practical path forward.
Steps for completing your project
After purchasing the project, send requirements so Jahanzaib can start the project.
Delivery time starts when Jahanzaib receives requirements from you.
Jahanzaib works on your project following the steps below.
Revisions may occur after the delivery date.
Requirements review
I review your requirements and confirm the core AI use case and tech scope with you before writing any code, so we're aligned on exactly what's being built
Core app build
I build the core application: authentication, database structure, and the main product screens your users will interact with.
