Portfolio

Products andprojects.

First the products we build and maintain ourselves, then the work we built for the companies and professionals who asked for it.

Products

Everything we products

None of these was handed over and closed: they stay with us, with releases and maintenance.

Mobile app2023

SpaceClub

A platform for nightlife that puts guests, promoters and venues in the same place: events, digital tickets, table booking and QR entry in one experience.

Estimation engine2026

Metis

A software effort estimation engine. From a requirement and a handful of structural inputs it returns a median estimate, a calibrated 90% confidence interval and the closest projects in the history it was trained on.

Library2026

Kdrant

A Kotlin client for the Qdrant vector database. Every operation is a suspend function, and collections, points and filters are declared through a type-safe DSL. Two transport engines, REST and gRPC, sit behind one interface, and the REST engine runs on the JVM and eight Kotlin/Native targets.

Library2026

Kmemo

A semantic cache for LLM calls. It recognises requests it has already answered even when they are worded differently, and rejects the ones where similarity is high but the right answer is not the same. The core compiles for the JVM, iOS, macOS, Linux, Windows, JS and WasmJS.

Library2026

Fluttorch

A typed bridge between a PyTorch export and a Flutter app. The exporter writes the artifact, its manifest and its goldens in one command, and the Dart API is generated from the manifest. The goldens replay in your tests: the parity gate compares the outputs against the recorded tolerance and fails the build when they exceed it.

GitHub App2026

TrueUp

A GitHub App that reports what a pull request makes possible and what it reimplements. It computes the effect profile of a unit of code: the reads, the writes, the calls it can reach and the depth at which the analysis gave up. Read against the merge base it yields the capabilities the change introduces; read against the rest of the repository it yields the code that already does that work.
