AI/ML EngineerGenerative AI & Agentic Systems

Kolchelma Sai KiranBuilding intelligent systems with LLMs, agents and retrieval.

1+ years building enterprise Generative AI, agentic and RAG systems for pharmaceutical and business intelligence use cases — agent orchestration, MCP tooling, knowledge graphs, safety guardrails and the evaluation harnesses that prove any of it works.

What I work on

From agent orchestration down to the retrieval layer

The work spans the whole stack of an AI system — routing and orchestration at the top, tool protocols and memory in the middle, graph and vector retrieval underneath, and evaluation across all of it.

Generative AI

Agent orchestration, retrieval, and evaluation.

Clinical Knowledge Graph RAG

Avira Digital Technologies — BMS client

A clinical Q&A retrieval system that moved from hybrid-search RAG to Graph RAG once relationship modeling became the real bottleneck.

Agentic Data Structuring & Query Platform

Avira Digital Technologies — BMS client

An orchestrator/sub-agent pipeline that turns raw multi-source data into tagged, queryable records — and answers questions about it in plain English.

Meta-RAG — Adaptive Model-Routing Gateway

Self-directed project

A self-directed inference gateway that classifies query complexity and routes across retrieval strategies and model tiers — then tunes its own thresholds.

Open to freelancing

Available for selected AI/ML projects

Taking on a small number of engagements alongside full-time work — which means I am selective, and honest about timelines before we start.

Custom RAG Systems

Retrieval over your own documents, data or knowledge base - including the cases where naive chunk retrieval falls apart and the domain needs to be modeled as a graph.

AI Agents & Agentic Workflows

Multi-agent systems that do real work against real tools - orchestrator/sub-agent architectures rather than one prompt asked to do everything.

MCP Tool Servers & Integrations

Standardized tool access for your agents, so adding the next integration does not mean inventing another bespoke protocol.

LLM Chatbots & Assistants

Assistants grounded in your content that answer from what you actually published, and say so when they do not know.

Natural Language to SQL / Query

Let non-engineers ask your database questions in plain English, against the live schema rather than a stale snapshot.

Guardrails & AI Safety Review

Input and output screening for systems that touch regulated or personal data - and a look at what your agent does when someone tries to talk it out of its instructions.
