About Kunj

I build software that works in production, whether that's a backend API, an AI-powered agent, or a CI/CD pipeline that ships code reliably.

I'm a Berlin-based freelance engineer working across software engineering, AI/LLM integration, and DevOps. I don't just write code. I solve the business problem behind it.

Right now, I'm co-building an AI voice agent startup that handles customer calls 24/7, collects data, classifies urgency, and syncs into a CRM. I built the full backend, AI logic, and integration layer, live and processing real calls.

What I can do for you:
  • SOFTWARE ENGINEERING
→ Backend APIs in Python (FastAPI, Flask), full-stack with React/Node.js
→ Database design, third-party integrations, performance optimization
  • AI & LLM INTEGRATION
→ Custom AI agents, conversational pipelines, prompt engineering
→ OpenAI & Anthropic API integrations, voice AI, intelligent automation
  • DEVOPS & CLOUD
→ Docker, Kubernetes, CI/CD pipelines
→ AWS & Azure infrastructure, cloud migration, monitoring

  • How I work: Fast communication, honest timelines, no surprises. I've worked with technical teams and non-technical business owners, I adapt and focus on delivering results.
Tech: Python, FastAPI, Flask, Node.js, React, SQL, OpenAI API, Anthropic API, Docker, Kubernetes, AWS, Azure, Terraform, Solidity
