Hi, I'm Konstantin Burkalev

The aquarium keeper’s journal that answers: when did I last do this — and what happened then?

A fish looks sick again — open the journal and see what you treated with last winter, at what temperature, and whether it helped. Water changes, treatments with their outcomes, arrivals, losses, moves between tanks and quarantine — logged in a tap or two, standing at the tank with wet hands, with photos of the fish themselves on the timeline.

One Flutter codebase for iPhone (capture at the tank) and Mac (the whole fishroom at a glance) — grown on five years of my own reef’s records before anyone else’s.

The garden diary that remembers what grew where.

Every spring the same question comes up at the plot: what was on this bed last year — and the year before? GardenBeds keeps the beds laid out the way they stand on the ground, shows each one’s history season by season, and at planting time gently flags crop rotation: «carrots were here last year». A hint, never a block — the gardener decides.

Recording a planting takes about two taps, harvests and photos join the same timeline. Built for one very specific gardener — my wife — which is exactly what keeps it simpler than the Notes app.

An autonomous AI coding agent loop with a terminal admin dashboard.

Ralphy drives an AI coding agent to implement one user story per iteration — planning, implementing, verifying, and committing autonomously. It supports git worktree isolation and session management, and works with OpenCode, Claude Code, and Amp as the underlying AI tool.

A Go-based terminal UI lets you monitor running sessions, watch logs and progress in real time, and manage sessions (pause, resume, kill) with vim-style navigation.

Convention-aware project intelligence for AI coding agents.

Seshat builds and maintains a per-project knowledge graph of conventions, patterns, and architectural decisions, and exposes it to AI agents via an MCP server.

Agents query Seshat before writing code, so generated changes match the project’s existing style and rules — not just whatever the model defaults to.

The Semantic Layer for Building Data Applications.

It helps data engineers and application developers access data from modern data stores, organize it into consistent definitions, and deliver it to every application.

Cube was designed to work with all SQL-enabled data sources, including cloud data warehouses like Snowflake or Google BigQuery, query engines like Presto or Amazon Athena, and application databases like Postgres. Cube has a built-in relational caching engine to provide sub-second latency and high concurrency for API requests.

WAMP is an open standard WebSocket subprotocol that provides two application messaging patterns in one unified protocol:

• Remote Procedure Calls (RPC)
• Publish & Subscribe messaging

I am one of the editors, the developers of the protocol itself, as well as the author and contributor of several implementations (see other projects).

Using WAMP you can build distributed systems out of application components which are loosely coupled and communicate in (soft) real-time.

I have a few talks and presentations about it. Check it out:

• “WAMP as a platform for composite SOA applications and its implementation on Lua” slides
• A blog post about my WAMP related presentation at Highload++ 2017 with videos, slides, and useful links (in russian)

Feature-rich lightweight WAMP (WebSocket Application Messaging Protocol) Javascript implementation.

Wampy.js is javascript library, that runs both in browser and node.js environments, and even in react native environment.

It implements WAMP v2 specification on top of WebSocket object, also provides additional features like auto reconnecting and automatic resubscription.

Wampy supports JSON, MessagePack and CBOR serializers and has plugin system for different WAMP auth options. It has no external dependencies (by default) and is easy to use.

WAMP router library, client library and router service.

Nexus implements most of the features defined in the WAMP-protocol advanced profile. The nexus project is written in Go and designed for highly concurrent asynchronous I/O. The nexus router provides extended functionality.

Nexus supports JSON, MessagePack and CBOR serializers and can be easily extended to run on top of other transports besides WebSockets.

A Home Assistant–powered smart aquarium with proactive monitoring and automation.

I love my aquarium, and being an automation addict, I wrapped it in sensors and automations: water-temperature control for the heater, water-quality alerts, oxygen and air-pump monitoring, and light control — so I always know it’s healthy and happy, even when I’m away.

It’s an ongoing series of notes on the devices, sensors, and Home Assistant automations behind it.

A podcast about software development and its surroundings.

I started recording the podcast back in 2013 and am still recording it. This is a hobby project that I do as much as I can.

In each episode I talk to a guest from the IT world, a professional in his field. It can be a developer in any field and in any language, an author of a book or even a programming language, a creator of an interesting service or application, a tester, an architect, or even a CTO.

The podcast allows me to have a broad outlook on the IT world, to follow trends and technologies and have an idea of how and where they can be used.

The podcast is recorded in Russian.
