I build AI Agents, AI Chatbots, RAG systems, workflow automation platforms, SaaS applications, and custom web software for startups and established businesses.
For the past nine years, I have worked with companies across FinTech, HealthTech, Aviation, Real Estate, E-Commerce, Logistics, and SaaS, helping them automate processes, launch products, improve operations, and scale their platforms.
Most clients come to me when they need more than a developer. They need someone who can understand the business requirements, design the architecture, build the system, integrate third-party services, deploy it, and support it after launch.
I have delivered aviation training platforms, healthcare scheduling systems, enterprise CRM applications, AI-powered document processing tools, RAG knowledge assistants, workflow automation systems, analytics platforms, custom business software, and multi-tenant SaaS products used by real customers every day.
Core areas I can help with:
✅ AI Agent Development
✅ AI Chatbot Development
✅ Retrieval-Augmented Generation (RAG)
✅ OpenAI, Claude, and Gemini Integrations
✅ LangChain, LangGraph, and LlamaIndex
✅ MCP Server Development
✅ n8n, Make, and Workflow Automation
✅ SaaS Application Development
✅ Full-Stack Web Development
✅ Python, FastAPI, Django
✅ React, Next.js, Node.js, Laravel
✅ CRM Development and Business Applications
✅ API Integrations and Third-Party Services
✅ PostgreSQL, MongoDB, Supabase
✅ AWS, Docker, Kubernetes
Some recent projects include AI-powered SaaS platforms, healthcare workflow automation, aviation training software, CRM systems, document processing tools, invoice automation solutions, analytics dashboards, enterprise web applications, and intelligent business automation systems.
I work across the full lifecycle of a product, from planning and architecture to development, deployment, integrations, optimisation, and long-term support. The goal is always the same: build reliable software that solves real business problems and continues to perform as the business grows.
If you already have requirements, documentation, wireframes, or even just an idea, send them over. I will review everything, identify potential challenges, and outline the most practical approach before development begins.
For larger projects, you can also book a consultation directly through my profile to discuss architecture, scope, timelines, and technical decisions before committing to development.

I help take products from an idea, prototype, or legacy system to a production-ready solution, covering technical planning, architecture, frontend, backend, cloud, integrations, QA, deployment, and ongoing development.
⚡ WHAT SETS ME APART
→ From idea to production
I look beyond individual tickets and focus on the product, users, workflows, and business goals behind the code.
Before development starts, I help clarify the technical approach, key workflows, risks, and feature priorities so engineering time goes where it creates the most value.
→ AI-enhanced development
I actively use Claude and modern AI engineering tools to accelerate code analysis, implementation, rapid prototyping, and repetitive development work.
The result is faster execution combined with senior technical judgment around architecture, code quality, security, and long-term maintainability.
→ End-to-end technical ownership
Discovery → Architecture → Frontend → Backend → APIs → Cloud → QA → Deployment → Maintenance
Whether we're launching a new SaaS product or modernizing an existing platform, I focus on building software that is ready for real users and future growth.
