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

🤖 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.
