You will get A full-stack Next.js web application or AI SaaS MVP
Project details
Building an MVP or web app shouldn't mean dealing with messy code, broken state management, or unhandled edge cases.
I build production-ready Next.js and Node.js applications that are fast, easy to maintain, and ready for real users. Whether you need an AI tool, a SaaS dashboard with Stripe billing, or a clean custom web app, I write clean TypeScript code with proper database structures and secure API endpoints.
You get a fully deployed app on Vercel or your cloud host, a clean GitHub repository, and post-launch support to make sure everything runs smoothly after launch.

About Oleksandra
Full-Stack Engineer | SaaS & AI Integration | Node.js React n8n Stripe
Kyiv, Ukraine - 6:57 pm local time
- SaaS MVPs & Web Apps: Built with Next.js, React, and Node.js.
- Workflow Automations: Connected using n8n, Make, and Zapier to handle complex backend logic.
I don't just write features - I deliver full systems, from the UI to the database to the automated workflows behind it. Stripe billing, AI assistants that actually understand your data, or a custom internal tool - I ship it ready for real users.
Here is how we can work together:
🚀 SaaS & Full-Stack Web Development
I build scalable web applications from scratch with a focus on clean architecture, security, and high performance.
Frontend Tech Stack: Next.js, React, TypeScript, TailwindCSS, HTML5, CSS3, Redux / Zustand.
Backend & Core: NestJS, Node.js (Express), REST APIs, GraphQL, Webhooks.
Authentication & Payments: Secure user management via Clerk / NextAuth and robust payment flows via Stripe Integration (subscriptions, webhooks, recurring billing, invoices).
🤖 AI Integration & Smart Agents
I connect your applications to powerful Large Language Models (LLMs) to automate data processing, content generation, and customer interactions.
AI API Integration: OpenAI API (GPT-4), Claude (Anthropic), Replicate API for advanced photo processing (image enhancement, background removal, object generation, photo variations).
AI Assistants & Chatbots: Custom AI shopping assistants, context-aware customer support bots tailored to your product catalog or business logic.
RAG Pipelines: Retrieval-Augmented Generation for searching, parsing, and analyzing heavy PDFs, CSVs, and corporate internal documentation without hallucinations.
⚙️ Workflow Automation (n8n & Make)
Stop wasting hours on manual tasks. I design automated workflows that sync your tech stack, apps, and CRMs seamlessly.
Building complex, multi-step scenarios in n8n, Make (Integromat), and Zapier.
CRMs & Tools Automation: Connecting HubSpot, Salesforce, Airtable, Notion, Google Sheets, Slack, and Telegram.
Hybrid Solutions: Writing custom JavaScript/TypeScript code inside automation nodes when standard platform tools are not enough.
📊 Databases & Vector Storage
Data integrity and fast retrieval are key for modern SaaS and AI systems. I design optimal database schemas and vector pipelines.
Relational Databases: PostgreSQL, MySQL managed via Prisma ORM or TypeORM.
NoSQL Databases: MongoDB, Redis (for caching and session management).
Vector Databases (for RAG & AI): Pinecone, Supabase Vector, ChromaDB for storing and querying text embeddings.
☁️ Cloud, Deployment & DevOps
Your application needs to be live, monitored, and scalable. I handle the deployment process to ensure smooth production launches.
Cloud Platforms: Amazon Web Services (AWS - EC2, S3), Google Cloud Platform (GCP).
Hosting & CI/CD: Vercel, Render, Railway, DigitalOcean.
Containerization: Docker for consistent development and deployment environments.
🤝 Why choose me?
I leverage advanced AI-assisted development tools (like Cursor and Claude), which allows me to deliver high-quality, bug-free MVPs up to 3x faster than traditional developers, saving your budget and significantly accelerating your time-to-market.
