Fix Workflow Automation Bug in AI-Integrated Bot
Karishna did an excellent job debugging and stabilizing our AI-integrated workflow automation bot. He quickly identified timing and sequencing issues, refactored the control logic, and added proper error handling. Highly recommend for any Python/AI automation work.

Mini Internal Tool – React + Firebase (2-Day Build)
Karishna was outstanding to work with! He delivered the internal tool exactly as requested, clean, responsive, and fully functional. Everything from Firebase Auth to Firestore integration, inline editing, and filters was implemented flawlessly. Communication was clear throughout, and the project was completed right on schedule. I’ll definitely work with him again for future Firebase + React projects.

Job Success
Melbourne, Australia - 3:07 pm local time
From autonomous AI agents and RAG pipelines to AI chatbots, workflow automation, and LLM integrations, I build systems designed for real-world reliability not just demos.
If you're building an AI-powered product, I can help you move from idea to prototype to production.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
AI Solutions I Build
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✅ Autonomous AI Agents & Multi-Agent Systems

⦿ Prompt engineering, evaluation systems, and hallucination mitigation
⦿ Cost optimization and production-ready deployment
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Why Clients Choose Me
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Most AI projects fail in execution where reliability, orchestration, context handling, fallback systems, and production stability matter.
I focus on building AI systems that are:
✔ Reliable in production
✔ Scalable and maintainable
✔ Cost-efficient and optimized
✔ Integrated with existing tools and workflows
✔ Designed around measurable business outcomes
I think through the full architecture:
Agent orchestration • Memory systems • Tool routing • RAG pipelines • Error handling • Evaluation layers • API integrations • Production deployment
