FAQ
Can you build a full AI chatbot with RAG over my data?
Yes. I implement robust ChatGPT/Claude integrations with embeddings, vector databases (like Postgres with pgvector), RAG pipelines, and secure APIs for accurate, private, and reliable AI responses.
What’s the difference between Standard and Premium packages?
Standards offers a demo-ready AI web application with core flows and a basic AI integration. Premium adds enterprise-grade features like scalability, advanced payments (Stripe), comprehensive testing, CI/CD pipelines (Jenkins/Kubernetes), and detailed analytics. (p. 1)
Do I get full source code and ownership?
Yes, absolutely. Upon project completion and final payment, full repository access, version control history, and all intellectual property rights are transferred to you. You own the code and all assets.
How do you manage web development timelines and project delivery?
I finalize the scope and then work in agile weekly sprints with clear milestones, rigorous QA, and regular demos. I utilize structured methodologies to provide clear estimates and ensure on-time delivery.
Can you integrate my CRM, payment gateway, or third-party APIs?
Absolutely. My expertise includes integrating various platforms like Stripe, HubSpot, and Notion, alongside building custom secure REST/GraphQL APIs and high-performance Kafka messaging systems.
Can I see some of your work samples or case studies?
Yes, I have a portfolio of work, including details on the AI-driven IVR system for Citi Bank and automated recovery systems for Barclays. Please drop me a message, and I will share relevant samples.
Do you provide post-launch support or maintenance?
Yes, I typically include a period of free post-launch support in my premium packages to ensure a smooth transition to production. We can discuss extended support contracts as needed.
Are you open to being hired as a permanent full-stack AI web developer?
My current focus is on freelance and contract projects through this platform, but I am open to discussing high-impact, long-term opportunities that align with my expertise in large-scale systems architecture.
