Hi, my name is

Madi Zhanbyrtayev

I build robust backend systems & AI solutions.

Senior Software Engineer with 6+ years of experience in backend development, cloud infrastructure, and machine learning. I design scalable architectures and lead teams to deliver impactful solutions.

01. About Me

I'm a Senior Software Engineer from Kazakhstan with over 6 years of experience building backend systems, cloud infrastructure, and AI-powered applications. My journey started with research in computer vision at the University of Alberta, where I earned my Master's in Computing Science.

I specialize in designing scalable architectures, from document processing pipelines with AWS Step Functions to multi-agent AI systems using LangChain and LangGraph. Currently diving deep into Rust, high-load systems, RAG implementations, and MCP development.

At Provectus, I'm building an AI-powered insurance document analysis platform, architecting serverless pipelines that process healthcare claims and financial filings at scale. I'm always interested in challenging projects involving distributed systems, machine learning, and cloud-native architectures.

Technologies I work with:

Languages

Python
Rust
Go

Frameworks

FastAPI
LangChain
React

Cloud & DevOps

AWS
GCP
Docker
Kubernetes

Databases

PostgreSQL
Redis
