Hi, I’m Aparna Sunil
AI & Machine LearningEngineer
I build production AI systems with APIs, MCP, LangGraph, RAG and prompt workflows on AWS.
What I do
Production AI, from the model to the service around it.
RAG & knowledge systems
Ingestion pipelines, vector search and grounded answers with hallucination checks built in.
- Bedrock
- pgvector
- ChromaDB
Backend on AWS
Serverless services that hold up with many customers at once. APIs, Lambda, DynamoDB and SQS.
- Python
- Lambda
- Docker
AI workflows
Connected AI services and automations built with n8n, Python and model APIs.
- PyTorch
- scikit-learn
- Pandas
About me
I’m an AI engineer based in Kochi. My work sits where models meet infrastructure: the contracts between services, the guards in front of generation, and the prompts that have to behave when nobody is watching.
I came to this through physics, then a master’s in data analytics, then a run of end-to-end projects built to be used, not demoed. The part I like most is when “works on my machine” becomes “works for every customer at once”.
How I work
01Understand the system and how it fails
02Define the contract first, then build
03Verify in production, not just locally

Selected work
Production systems from my work as an AI engineer.
Project
SocialTrend AI
Built backend and AI systems for a multi-tenant content automation platform on AWS. My work covered MCP integrations, compliance workflows, knowledge-base ingestion, scheduling safeguards, and production prompt systems.
What I built
- Built secure MCP tools connecting AI assistants with product workflows
- Developed components for a LangGraph compliance pipeline with privacy-aware content checks
- Improved the reliability of knowledge ingestion and multi-tenant scheduling
- Designed production prompts for social content, video, and image generation
Projects
Built end to end, on my own time.
