Web applications
Marketing sites, marketplaces, and full SaaS platforms with accounts, billing and an admin side. Next.js and React on the front, whatever the job actually needs behind it.
Software engineering · Vilnius, Lithuania · Since 2022
From landing page to Layer-1.
We build web and mobile products end to end — frontend, backend, infrastructure — and the parts most teams pass on: AI integrations, blockchain, cryptography.
What we do
Six fields we work in.
Mobile applications
Native iOS and Android, with Flutter or React Native where that fits better. We take an app through store review and out the other side, not just to a build.
Backends, APIs and automation
Rust, Go, Node and Python services. Databases, queues, payments, scraping engines, bots, and the deployment and monitoring that keep them running.
AI integrations
Language models doing real work inside a product — generation pipelines, conversational agents, voice. Computer vision where a camera is part of the system.
Blockchain and Web3
Token contracts, wallet integrations and dApps on EVM chains and Solana — through to a Layer-1 written from scratch, with its own explorer and verification portal.
Cryptography
End-to-end encryption, key management, threshold signing, and migration to the NIST post-quantum standards. We write the core ourselves, usually in Rust.
Work
Some of what we have built.
Qwing Messenger
Encrypted messenger for iOS and Android with its own cryptographic core. No account, no phone number. Published on Google Play across 176 countries.
QuantumWing
A Layer-1 blockchain with post-quantum block signatures and EVM-compatible RPC. Ten-validator network with a public explorer.
PracticalRadar
Worldwide search and registration reminders for practical shooting competitions. Next.js platform with its own match database.
Trust Fabric
Permissioned ledger for consortia: BFT consensus, M-of-N key custody where the key is never reassembled, and a public portal anyone can verify a record against.
