You will get A React or Next.js web application built, fixed, or improved.

Project details
Your React or Next.js app works... until one feature suddenly breaks. An API stops connecting, authentication fails, or a new feature becomes harder to add than expected.
I help fix and improve existing React/Next.js apps without rewriting your project.
I can help with:
• Bugs, errors & broken functionality
• New features & reusable components
• REST API integration & frontend/backend issues
• Authentication & protected routes
• Forms, CRUD, dashboards, search & pagination
• Responsive UI & TypeScript/JavaScript issues
• Performance and code-quality improvements
I first understand your existing code, find the real cause, then make focused, tested changes.
Need backend work too? I also work with Node.js, NestJS, Express, FastAPI, PostgreSQL, Prisma, and MongoDB.
Have a bug or feature in mind? Send me the details and let's fix it.

About Samson
Full-Stack Developer | React, Next.js, Node.js, API | AI SaaS MVPs
Addis Ababa, Ethiopia - 7:31 am local time
I help startups and businesses turn ideas into working web, mobile, and AI-powered products. I build the full product, from the user interface and backend APIs to authentication, databases, AI features, and deployment.
I work mainly with React, Next.js, TypeScript, Node.js, NestJS, FastAPI, PostgreSQL, Prisma, Supabase, and React Native, and I can integrate AI capabilities using tools such as OpenAI and Gemini APIs, RAG, embeddings, and vector search.
What I can help you build:
• Full-stack web applications: React and Next.js frontends with reliable backend systems
• AI-powered applications: AI assistants, document Q&A, RAG systems, semantic search, summarization, and intelligent workflows
• SaaS & MVPs: dashboards, management platforms, internal tools, and business applications
• Backend systems: NestJS, Node.js, and FastAPI APIs, database design, authentication, and RBAC
• Mobile applications: cross-platform apps with React Native and Expo
• Existing applications: bug fixes, new features, API integrations, performance improvements, and code cleanup.
I’ve worked on projects ranging from task management APIs and admin dashboards to AI-powered hiring tools, PDF reading assistants, mobile apps, and data-driven platforms.
What matters most to me is building software that is easy to use, easy to maintain, and actually solves the problem.
My usual approach is simple:
Understand the problem → define the solution → build in small milestones → test → deliver.
You'll always know what I'm working on and what comes next. I also write documentation and keep the code organized so the project isn't difficult to maintain after delivery. I care about clean structure, clear communication, and delivering work that another developer can understand and continue without confusion.
If you already have an idea, an existing application that needs work, or a specific problem you're trying to solve, send me a message and tell me what you're building. I'll take a look and we can figure out the best way to approach it.
