Looking for a React Native developer
Pratik & his team did a wonderful job, we had a strict deadline and they gave their best & tried to meet the timeline. They managed to complete the project & deployed our apps on the play store + AppStore. I enjoyed working with Pratik & his team and will likely have additional jobs for him in the future.

I help startups and businesses turn LLM ideas into production-ready AI agents, RAG systems, and automation workflows that connect to their data, APIs, and existing software.
--------------------------------------------------
How we build a production-ready AI system:
--------------------------------------------------
1. Workflow Mapping: Pinpoint the exact business processes, data sources, and user actions that need automation.
2. Agent Architecture: Design custom agent memory, tool permissions, and fallback behaviours so the agent never gets stuck.
3. Secure RAG Pipelines: Connect your databases and proprietary files through a retrieval pipeline with verified citations and granular access controls.
4. Seamless Integration: Connect OpenAI, Claude, or local LLMs to your current software (APIs, WhatsApp, Slack, Zapier, Make, n8n).
5. Evals & Monitoring: Deploy with rigorous testing, logging, error handling, and human-in-the-loop approval steps.
