Hey! With experience more than 10 years as developer this feels like my kind of project. You already have an MVP, so the real challenge is making the agents reliable (clean JSON, predictable outputs, proper parsing). That’s exactly what I usually handle with FastAPI + AI workflows. I’m comfortable taking ownership end to end from stabilizing CrewAI agents, integrating real APIs, to getting everything production ready on your stack. I am available for the full 2–3 month timeline with US overlap. Kindly contact me for further discussion.

Hi, This is Elias from Miami. I checked your project description and understand you’re looking to polish and expand your Veritas AI SaaS MVP—FastAPI backend with CrewAI agents—into a production-ready platform, adding reliable JSON output, new agent features, dashboards, user accounts, and production hardening over the next 2–3 months. I’ve worked on similar FastAPI SaaS projects with agent orchestration, real-time dashboards, and structured AI output, so I’m familiar with prompt engineering, API integrations, and production-grade deployments. My approach would be to start with a setup + test milestone to ensure reliable JSON responses and smooth agent execution, then progressively add the new agents, dashboard functionality, user/project management, and robust logging/error handling, all while keeping the system scalable and maintainable. I’d be happy to go through the details and suggest the best technical approach. I have a few questions to get a better understanding: Q1 – Do you have preferred APIs for the name/keyword/domain availability checks, or should I recommend the best options? Q2 – Should the dashboard show live agent progress in real-time (WebSocket/HTMX) or is periodic refresh sufficient? Q3 – For project saving, do you want full versioned history per user, or just the latest snapshot? Looking forward to hearing from you.
