Voice Agent
Rohan is an amazing AI agent developer. He checked our non-functional agent, fully rebuilt it, fixed tons of issues (even those not directly related to his area of responsibility), and delivered the task on time. The communication was clear and easy - just want to recommend Rohan to work with highly. Thank you.

Full Stack Developer (PHP Laravel & React) Needed
Really glad we found Rohan. We needed a Full Stack Developer who actually understands PHP Laravel & React inside out. He dug deep into our codebase, spotted things we missed, and explained everything in a way that actually made sense. Quick replies, clear updates, never had to chase him down or wonder what was going on. 100% coming back for future work.

VOICE AGENT DEVELOPMENT
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Voice AI is my sharpest edge. I build inbound and outbound voice agents on the Twilio API and OpenAI Realtime API that answer calls, qualify leads, book appointments and log everything back into your CRM software. I engineer for latency first, because a voice bot that pauses for two seconds gets hung up on. My production agents respond in under 300ms and hand off to a human the moment the conversation needs one.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
AI AGENT DEVELOPMENT AND AUTOMATION
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
AI agent development is my primary engineering focus. I design full agentic pipelines with Python, LangChain and LangGraph, from RAG powered retrieval with vector databases like Pinecone, Qdrant and Supabase through to autonomous multi agent orchestration. Every build applies LLM Prompt Engineering discipline and AI model integration through the OpenAI API and Claude API. I also handle chatbot development, AI bot builds for support and sales, and n8n automation that connects your CRM software, email, calendars and internal tools. I treat AI as a business transformation, not a feature addition.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
FULL STACK DEVELOPMENT
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Full stack development is the base under all my AI work. I build back ends on Python, FastAPI, Django, Flask, Node.js, NestJS, Express.js, PHP, Laravel and Ruby on Rails. Front ends run on React, Vue.js, Next.js, Angular, TypeScript, JavaScript, HTML, HTML5, CSS3 and Tailwind CSS. Databases are PostgreSQL, MySQL, MongoDB and Supabase. Deployments run on Docker and Amazon Web Services with Git and CI CD. Every system I deliver is production grade, documented and built to scale.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
My working style is simple. Clear scope, honest estimates, weekly demos and code you can read after I am gone.
Tell me what is eating your team's hours. I will map out where an AI agent fits, what it costs and what it saves, before you spend money on the wrong build.
