With my distinguished background in mobile app development, Node.js, Python, and React Native, I'm well-equipped to handle Role 2: Frontend / React Native Engineer. Combining my tech prowess with an exceptional ability to integrate APIs and my background in building conversational UIs, I'll help create an engaging and intuitive mobile product. While thriving in remote settings. In your quest for a professional programmer with valuable production experience, look no further. Notably, I developed a user-centric application that made use of the FastAPI Python framework coupled with Neo4j graphs to manage complex relationships efficiently. This project combines with my proficiency in PostgreSQL and Docker to give me a clear edge over other candidates for the backend-focused Role 1. Through regular updates and weekly demos, I will keep you in the loop and effectively include your feedback in the project's trajectory. Lastly, as an ardent believer of clarity, ownership, and execution speed when it comes to project management, you'll find in me a freelancer who is devoted to delivering not just an MVP but an impressive product. My time-keeping skills allow scheduled workflows, thereby meeting weekly or milestone-based payments without failure. My competitive hourly rate aligns with the value I bring—the perfect metier for your MVP-focused freelance engagement. Hire me, and let’s make this MVP project something we can both be proud of!

Hi there, I have reviewed your Conversational AI Product Development MVP and I am a strong fit for the Backend / AI Engineer role based on my experience shipping conversational systems that go beyond chat wrappers. I have 7+ years of experience handling Python and Node.js backends, including FastAPI services, PostgreSQL data models, graph-based relationships, and clean LLM API integrations with OpenAI and Claude. I have built AI-driven logic layers that combine structured data, graph traversal, and LLM reasoning in production systems. I regularly work with Dockerized services, REST APIs, and stateful conversational flows, and I am comfortable designing systems that are demo-ready on a weekly cadence. I reduce delivery risk by keeping the architecture simple, validating AI behavior early, and shipping small, testable increments. I am available for 25–30 hours per week, can work time-and-material, and am open to occasional syncs in Gurgaon or NCR. Regards Chirag

With a solid 6+ years of experience in Full Stack Web and Mobile App Development, combined with my strong foundation in AI and Chatbots, I believe I'm an ideal fit for your Conversational AI Product project. In addition to my backend proficiency, I've got hands-on experience in frontend development using React Native and TypeScript that would match your requirements as well. I have indeed built mobile-first UI/UX flows with text/voice interaction features, Mobile UX understanding that would add value to this project. I understand the importance of ownership, clarity, and execution speed you've emphasized on for this MVP-focused project. My accustomed work ethics involving consistent weekly progress demonstrations paired with my global client handling has taught me flexibility and focus on a tight schedule.

Hi, Drawing on over 5 years of experience as a Full Stack Developer and Automation Expert, I am an ideal choice for your Conversational AI Product Development project. My proficiency in Python and Node.js dovetails perfectly with the backend and AI-driven requirements of the role. Additionally, my expertise in PostgreSQL and Neo4j will contribute to a comprehensive understanding of graph-based relationships. Importantly, I have implemented LLM APIs from OpenAI and Azure in previous projects, which aligns directly with your needs. In terms of project approach, I pride myself on clean, maintainable code that is performance-optimized. I closely adhere to API design principles when developing backend services and leverage my strong data flow understanding to integrate frontend UIs seamlessly. For example, in one noteworthy project involving automated workflows using n8n, Make, and Zapier, I had to ensure trouble-free API integrations across multiple platforms - a skill that will translate directly to your project requirements. Let's have a quick chat to discuss your project in details Warm regards Usama

@remoruslime

Using a clean REST API built on FastAPI, Node.js, and PostgreSQL, along with a graph-based model, I can integrate OpenAI and Claude's LLM APIs with structured prompts, response control, and abstractions suitable for a production environment. I will build the AI ​​backend from scratch, based on sound principles, and take full responsibility for building the MVP from start to finish. I also have a frontend developer who is a good fit for your requirements and whom I've worked with for many years. If you'd like, we can all discuss this together. Best regards, James.

I’ve reviewed your requirements and clearly understand that this is not a ChatGPT wrapper, but a production-grade conversational AI MVP that needs clean architecture, fast iteration, and real ownership. Main focus areas: • Backend APIs with FastAPI / Node and clean LLM integration • AI-driven logic with context, memory & graph relationships • PostgreSQL + Neo4j (or graph-first modeling) • Mobile-first conversational UI (text/voice) in React Native • Dockerized services with demo-ready builds Process flow: Quick chat / call → MVP scope & architecture → Backend + AI logic build → Mobile UI implementation → API integration → Weekly demos → Iteration & delivery I’ve worked on conversational AI products and MVPs involving LLM orchestration, graph-based data models, real-time APIs, and React Native chat interfaces, shipping production systems—not prototypes. I can contribute 25–30 hrs/week (backend/AI) or 15–20 hrs/week (React Native), with time & material or milestone-based engagement, and flexible rates aligned to responsibility and ownership. I value clarity, execution speed, and shipping real products, happy to share relevant work, availability, and jump on a quick call to align.
