Software EngineerMIPT

Full-stack engineer with a physics-and-maths background. I ship products end to end — a tree-structured knowledge tool running on five platforms, an Obsidian plugin used by thousands, plugins that put Claude Code to work on real repositories, and the Python libraries and services underneath them.

    Product engineering

    One data model, every surface. Web, desktop, mobile and chat clients that stay in sync and keep working offline.

  • 02

    AI agent infrastructure

    Harnesses that let coding agents work on real repositories without breaking them: isolation, review gates, and a paper trail.

  • 03

    Backends & tooling

    The unglamorous half: typed APIs, schema migrations, packaging, and libraries other people install.

Treeno

Tree-structured notes on five surfaces, with an agent inside

Web appDesktop appMobile appTelegram Mini AppTelegram bot

A note-taking product where everything is a node in one tree — outlines, task breakdowns, kanban boards, structured fields. The same tree runs on the web, a Tauri desktop build, a Flutter mobile app, a Telegram Mini App and a Telegram bot, staying editable offline and reconciling when the network returns.

Lectorea

What to learn, and in what order — university lectures as a map

Web appPWAData pipelineOpen source

A free catalogue of university lecture courses on YouTube, arranged by what has to come first. Every course knows what it depends on and what it opens up, so a subject becomes a route instead of a pile of links: pick where you want to end up and the site lays out the path, prerequisite by prerequisite, with the recordings for each step. 236 courses across 39 fields, 12,500 lectures from 309 universities and channels, re-crawled every night.

Claude Code Plugins

A plugin marketplace that puts a coding agent to work on a real repository

Claude Code pluginCLIOpen source

Two published Claude Code plugins behind one marketplace command. make-better audits an existing codebase across nine topics and applies the fixes; feature builds every change in an isolated git worktree with its own port and lands it through a pull request. Both are configurable per project.

claude — /make-better
$ /make-better# picks the oldest subsystems, reviews each across nine topics Total: 104 findings across 5 systems.  - 13 bug fixes (applied automatically)  - 14 DRY refactors  - 11 architecture cleanups  - 13 consistency fixes  -  6 efficiency wins  - 16 tests added  - 18 doc-sync updates  - 10 completeness fixes  -  3 security each system on its own branch, merged back with --no-ff. nothing pushed.
make-better — flags
/make-better
Smart defaults — usually the three stalest systems.
/make-better 8
Review eight systems instead.
/make-better flutter 4
Four systems whose names match "flutter".
--no-discover
Skip discovery and go straight to review.
--rebuild
Force a full re-discovery of the subsystem registry first.
--yes
Unattended — no plan mode, no prompts, runs to completion.

Session Timeline

A live Gantt of every Claude Code session, read straight from local transcripts

CLI toolWeb dashboardOpen source

A browser dashboard that puts every Claude Code session on one shared time axis — when the agent was working, when the human was reading, every tool call and every subagent run. It reads the transcripts already on disk, so there are no hooks to install, no config to change and no dependencies to audit.

Network Trail

A guide to the social graph — paste a profile, get the structure behind it

Web appHTTP APIWorker fleetOpen source

A research platform that turns public social-network data into something you can navigate: it crawls a profile's connections through official APIs, works out which communities the graph splits into, and ranks the traits those communities share. Six services — a React front end, a Flask API, a domain layer, a distributed request worker, a FastAPI analysis service and a token pool — built over three years and now published as one repository.

ntrail — friend graph

bestconfig

One Config object over every place a Python project hides its settings

Python libraryOpen source

A configuration library that removes the setup step entirely. Instantiate Config() and it walks up from the current file to the project root, finds the YAML, JSON, INI, .env and Python config files along the way, folds in environment variables, and exposes the result through one typed accessor.

python
$ pip install bestconfig # app/main.py — config.yaml and .env live two levels upfrom bestconfig import Config config = Config("myconfig.json")# that was the entire configuration step mode = config.logger.mode        # 'WARNING'port = config.int('PORT')        # 5050pw   = config.get('DATABASE_PASSWORD')config.to_dict()  ->  every source, merged
sources it reads without being told
.yaml / .yml / .json
Parsed with native types — `port: 5050` arrives as an int.
.ini / .cfg
Standard section-based config files.
.py
Python config modules, skipped if they construct Config() themselves to avoid recursion.
.env / env_file
KEY=VALUE files, including values that parse as Python literals.
Environment variables
Existing and newly set, merged with the file sources.
dict
Plain dictionaries inserted at runtime via `config.insert(...)`.
accessors
config.name
Attribute access for the common case.
config['name']
Dict access — raises KeyError when absent.
config.get('a.b.c', default)
Dotted path to any depth, with a default instead of an exception.
config.int / float / str / list / dict
Typed getters that return None when the cast fails.
config.get_raw('key')
Opt out of type interpretation entirely.
config.assert_contains('key')
Fail loudly at startup if a required setting never loaded.

Netwik

A shared global note network inside Obsidian, used by thousands of vaults

Obsidian pluginWeb serviceOpen source

An Obsidian plugin that adds a public, collaboratively edited layer to a private vault. Any note can be published to a shared network, linked by URL, found through in-editor autocomplete, and edited by anyone — with changes synchronised back to every participant's vault.

Obsidian — command palette
Create note
Publish a new note into the shared network.
Update note
Pull the latest cloud changes for the note you are in.
Upload current note
Move an existing local note into the shared layer.
Sync base
Reconcile the local mirror with the cloud.
Copy obsidian url
Produce an obsidian://netwik?id=… link anyone with the plugin can open.
Delete remote note
Remove the note network-wide, not just from this vault.
