Project details
š¤ You will get a production ready AI agent and workflow automation system built with LangGraph, designed to automate your real business tasks with human-in-the-loop controls so you stay in charge.
I have 15+ years building full-stack and AI systems for enterprise platforms in media, travel, and real estate. I ship reliable, secure AI automation that your team can maintain and extend. No fragile demos, just solid work.
Here is what you get:
ā A scoping call to agree on goals and timeline
ā Custom multi-agent AI design with LangGraph
ā API integration for web search, databases, and your apps
ā ChatGPT, OpenAI, Claude, or Gemini model setup
ā Human approval steps for sensitive actions
ā Deployment on AWS Lambda or a FastAPI service
ā Clean, documented source code that you own
ā 1 week of support after delivery
Great for: SaaS automation, AI assistants, internal operations, research workflows, and customer support.
You see a working demo early and test it on your own scenarios, so nothing surprises you before the final build. Got a custom AI agent idea? Message me first and I will tell you how I would build it. š¬

AI Email Dashboard ā Gmail/Outlook Integration
Iām genuinely impressed with the work delivered on the AI Email Dashboard project. The integration with both Gmail and Outlook using OAuth was implemented seamlessly, making the sign-in experience smooth and secure without any need for installations. Your strong grasp of Google and Microsoft APIs was clearly reflected in how reliably the email data was fetched and processed.
The backend, built with FastAPI, is clean, efficient, and well-structured ā ensuring fast responses and secure handling of user data. On the frontend, the React/Next.js implementation provides a modern, intuitive dashboard thatās easy to navigate, with a professional look and feel.
I particularly appreciate how you managed to deliver the MVP within the tight 7-day timeline without compromising on quality. The smart email digests and summary features are functioning exactly as envisioned, setting a solid foundation for future enhancements.
Your attention to detail, clear communication, and ability to translate requirements into a polished product made the entire development process smooth. Excellent job ā this was a challenging build, and you delivered beyond expectations.

Job Success
Bengaluru, IndiaĀ - 7:41 pm local time
Most teams need both an AI specialist and a full-stack developer to ship a real product. I bring both skill sets together, so you can move from AI idea to production without juggling multiple freelancers.
ā Top Rated Upwork freelancer with production experience across AI, SaaS, cloud infrastructure, automation, and high-traffic web platforms.
You get one person responsible for the full build: backend, frontend, database architecture, API integrations, AI layer, and production deployment on AWS or GCP. The result is a product that is planned, built, and delivered as one connected system.
I also support legacy and high-traffic platform work, including PHP, Laravel, WordPress, WooCommerce, and Shopify modernization, performance tuning, custom plugins, API integrations, payment workflows, CMS and e-commerce systems, and AWS scaling for platforms serving 1M+ daily visitors.

š« Not a fit: vague experiments, unclear ownership, or tasks with no real business goal. I work best when I can understand the problem, suggest the right technical approach, and help deliver something useful.
š”ļø Low-risk way to start
We can begin with a small fixed-scope task, such as a proof of concept, technical review, or discovery sprint. You get a clear result first and can see how I work before committing to a larger build.
š© Send me 2ā3 sentences about what you are building. Within 24 hours, I will share a practical technical plan, an honest view of scope and fit, and the best way to start without wasting your time or budget.

Bikram Keshari works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery & Scope Call
We start with a scoping call to align on goals, sample tasks, success criteria, and timeline. You share API/DB access and allowed sources, and I confirm scope and deliverables, so you have full clarity before work begins.
Build, Demo & Refine
build the multi-agent workflow and share a live demo early. You test it on your real scenarios, we set human-in-the-loop approval checkpoints, and I refine outputs until it's reliable and production-ready.
