You will get a Production-Ready AI SaaS MVP: Scalable Node.js & FastAPI
Project details
I am a Senior Software Architect with 8+ years of experience, and I build SaaS products designed to handle your first 10,000 users on day one.
Why choose this project? I specialize in the "Power Stack": FastAPI for high-performance AI processing and Node.js for scalable real-time backend logic. Whether you are building a Generative AI tool or a complex B2B platform, I ensure your architecture is secure, modular, and cloud-ready.
What you get:
Senior-Level Architecture: Clean, documented code following industry best practices.
Security-First Mindset: JWT Auth, encrypted data, and protection against OWASP threats.
AI Ready: Seamless integration with OpenAI, Anthropic, or custom LLM pipelines.
Scalable Infrastructure: Dockerized environments ready for AWS, GCP, or Vercel.
[PROMO]: I am currently offering a 50% discount on my Starter and Standard tiers to build my Upwork reputation. Get $150/hr quality at a fraction of the cost while this offer lasts.
Let’s build a product your users will love and your investors will trust. Select a tier to get started.

About Kevin
Senior Full Stack Engineer | AI, Cloud and Scalable Systems
Eldoret, Kenya - 2:34 pm local time
I'm a senior full stack engineer with deep experience in Python (FastAPI, Django), JavaScript/TypeScript (Node.js, Next.js, React Native), and cloud infrastructure (AWS, Docker, Kubernetes). I've led projects from system design through to deployment, working with startups and enterprises to ship market-ready products on tight timelines.
What I deliver:
- Custom AI integrations: RAG pipelines, LLM agents, structured output parsing with Claude/GPT.
- Scalable backends: FastAPI or Node.js + PostgreSQL/Redis, built for high concurrency.
- Interactive dashboards: Next.js/React with live data, multi-tenant architectures.
- Cloud-native deployment: Vercel, AWS ECS, CI/CD pipelines, cron-based automation.
- Mobile apps: React Native/Flutter with secure authentication and offline-first capabilities.
I also bring a rigorous engineering mindset. Every system I design values scalability, maintainability, and security—I write code that's clean, tested, and hardened against common vulnerabilities because production software shouldn't break under load or expose data.
If you need an engineer who can read your existing codebase, write thorough tests, and ship features fast without cutting corners, let's talk.
Steps for completing your project
After purchasing the project, send requirements so Kevin can start the project.
Delivery time starts when Kevin receives requirements from you.
Kevin works on your project following the steps below.
Revisions may occur after the delivery date.
System Architecture & Schema Design
I will design the database schema and system architecture to ensure long-term scalability and security. We will define the API endpoints and data flow.
Core Backend Development & Security
I will build the "engine" of your application. This includes setting up the server, implementing JWT-based authentication, and coding the primary business logic.
