Osogbo, Nigeria - 8:48 pm local time
I'm a Senior Full-stack Developer who enjoys bridging design, product strategy, and engineering. My work combines visual clarity with dependable technical execution.
From startup MVPs to robust internal tools, I focus on creating interfaces that are simple to use and easy to scale.
- I design thoughtful digital products that feel fast, clear, and human.
- I build modern web and mobile applications with polished interfaces, reliable architecture, and a strong focus on user experience.
- I also build products using modern AI development tools that allow faster prototyping and iteration. Tools like;
• Bolt.new
• Lovable.dev
• Replit AI
• Cursor AI
• v0.dev
• Bubble
• AI-powered code generation workflows
This approach enables founders to launch MVPs more quickly, test ideas efficiently, and reduce development costs.
My Qualification:
- 7 years building digital products and scalable web applications
- AI SaaS and startup MVP development
- AI Agents, RAG systems, and LLM integration
- Rapid prototyping with AI and low-code platforms
- 20+ launches across SaaS and e-commerce
- 100% focus on measurable results
CORE SKILLS:
Frontend
- React, Next.js, JavaScript, TypeScript
- Tailwind, CSS Architecture
- Design systems and animations
Backend
- Node.js, Express, REST APIs
- Databases and authentication
- Performance and security basics
🤖 AI Integration & Automation
I have built real AI products, not just API wrappers. I integrate Claude (Anthropic), GPT-4, GPT-4o, and other LLMs into production applications, including chatbots, intelligent search, content generation, RAG (Retrieval Augmented Generation) pipelines, vector search with Pinecone, pgvector, and Weaviate, autonomous AI agents, and multi-step AI workflows. I also design and implement automation systems using n8n, Make, Zapier, and Airtable to eliminate manual work and scale operations. Prompt engineering, LangChain, LlamaIndex, embeddings, and AI-assisted development with Cursor are part of my daily workflow.
TOOLS:
- AI Integration: OpenAI, Claude, Gemini, LangChain, RAG, Llama, Grok, Google Dialogflow
- AI Development Tools: Bolt.new, Lovable.dev, Cursor AI, Replit AI, v0.dev, Bubble
- Automation: n8n, Make, Zapier
- Databases: PostgreSQL, MongoDB, Firebase, PostgreSQL, Supabase, MySQL
- Testing Technologies: Cypress, Mocha & Chai, Postman (API testing), Jest
- Cloud: AWS, GCP, Docker, CI/CD, Vercel, Heroku, Google Cloud, Microsoft Azure, Netlify
If you need a developer who can turn ideas into polished products, I would love to hear from you.
Let's create something meaningful together.
Steps for completing your project
After purchasing the project, send requirements so Yunus can start the project.
Delivery time starts when Yunus receives requirements from you.
Yunus works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery & Architecture Planning
We begin with a kickoff call to define user roles, core features, and the technical architecture (MERN/Next.js) required for your specific goals.
Database & Backend Development
I will set up the server-side logic using Node.js and design a structured, scalable database schema in PostgreSQL or MongoDB.
