With eight years of experience as a software engineer, I specialize in mobile app development, web development, and AI integration, delivering complete digital solutions.
On mobile, I build cross platform apps using React Native and Flutter for iOS and Android from one codebase. On the web, I develop full stack websites and web apps using React, Next.js, and WordPress. I also integrate AI powered features and chatbots to make apps and websites smarter, not just functional.
My focus stays the same on every project: clean code, real problem solving, and results that work for the end user.

FAQ
What is a voice AI chatbot / AI voice agent?
A voice AI chatbot (or AI voice agent) is an intelligent assistant powered by natural language processing that handles real-time voice or text conversations — answering calls, booking appointments, and supporting customers 24/7 inside your AI mobile app, website, or CRM.
Do you build with Vapi?
Yes. I specialize in Vapi AI voice agents and voice AI chatbots, and also work with Retell AI, OpenAI Realtime, and ElevenLabs depending on your use case.
Can you add an AI agent or voice AI chatbot to my AI mobile app?
Absolutely. I can integrate AI voice agents, chatbots, and automation into your existing AI mobile app or web app, or build a new one from scratch in React Native.
Will the AI agent connect to my CRM and other tools?
Yes I handle AI chatbot + CRM integration (HubSpot, Salesforce, Zoho) and automation via Zapier, Make, n8n, Google Sheets, and custom APIs.
Can I customize the voice, tone, and personality of the AI voice agent?
Fully. Voice, gender, accent, tone, and personality are tailored to match your brand.
Do you also build AI web apps?
Yes. Alongside AI mobile apps, I build AI web apps such as dashboards, SaaS tools, and internal tools.
Do I get the source code?
Yes you receive full source code, documentation, and code comments.
