Portrait of Mikhail Fediunin

The core is a Python backend: APIs with FastAPI, Django and Flask, asynchronous programming, integrations between systems, queues and messaging. On the frontend — React and Next.js: multi-page websites, interfaces for the backend and admin panels.

A separate direction is AI systems and data: RAG search over knowledge bases, work with LLMs and vector stores, numerical processing, interpolation and data visualisation.

I use AI tools — OpenAI Codex and Claude — in my work, but architectural decisions, checking the result and responsibility for the code stay with me.

Approach

How I work

  1. 01

    Architecture first

    I start from the problem, the data and the load, and only then choose the tools.

  2. 02

    Failure is part of the design

    Error handling, timeouts and logging go in from the start, not after the first incident.

  3. 03

    Simplicity pays off

    Every abstraction has to earn its place. Separate services only when they solve a real problem.

  4. 04

    Code for the team

    Types, tests and a clear structure keep a project easy to change.

Have a system to build?

Tell me about the problem — I'll come back with questions and a proposed approach.
