I will build a custom ai saas web application


About this gig
AI Systems Engineer | From Vision to Production
I turn ambitious product ideas into reliable, production-grade AI software. I design and ship systems, not templates, combining strong architecture with creative problem-solving and disciplined execution. Founders work with me when failure is expensive and reliability matters.
My focus is long-term stability, not short-term demos.
What I deliver: scalable backends, retrieval-augmented systems, autonomous agents, real-time voice and vision capabilities, and payment-ready SaaS platforms. Every system is built with security, observability, and maintainability at its core.
How I work: clear communication, structured milestones, and predictable delivery. I respect your time, protect your vision, and execute with precision. Friendly and approachable, yet deeply committed to quality, I operate as a dependable technical partner rather than just another developer.

FAQ
Do I need to pay for hosting and API costs?
Yes. You will need your own accounts for hosting (Vercel/AWS) and AI APIs (OpenAI/Anthropic). I will help you set these up. Usually, these costs are very low (<$20/mo) for a startup.
Is the Source Code included?
Yes, 100%. You own the intellectual property. I will push the clean, documented code to your GitHub repository upon completion.
Can you sign an NDA?
I work with stealth startups regularly and am happy to sign an NDA to protect your idea.
Can I convert this to a Mobile App later?
Yes! Since I use Next.js and React, the frontend logic can be easily ported to React Native for iOS/Android later. I offer a separate gig for this.
Do you offer support after delivery?
Yes. All Standard and Premium packages come with 30 Days of Free Bug-Fix Support. I also offer monthly maintenance retainers for ongoing feature updates.
Which AI models can you integrate?
I can integrate any API-based model or open-source models via Hosted APIs like Groq or open router.
