What we build, and what we are good at

Three competency domains, one team. Most engagements start in the first two — the software layer of a business and the control layer of a plant.

01 · Core competency

Software Engineering & Architecture

We design systems before we write them. That means picking an architecture that matches the actual load, the actual team and the actual lifetime of the product — not the one that is fashionable this year.

Where throughput and latency matter, we build according to the principles of mechanical sympathy: lock-free data structures, predictable allocation, and code written with the hardware in mind.

Architecture

  • Client-server (3-tier, n-tier)
  • Event-driven and message-based
  • Microservices, monolith, plugins
  • Component-based and SaaS

Delivery

  • Java, Scala, Angular
  • Agile — Scrum, Kanban, UseCase 2.0
  • CI/CD, Jira and Confluence
  • Cloud or on-premise deployment
02 · Core competency

Automation & Control

Control systems for buildings and process plants — from the field sensor to the dispatcher's screen. PLC application logic, operator interfaces, instrumentation and the regulation that keeps a plant inside its envelope.

We program the controllers, we build the SCADA on top, and we are on site for commissioning. Vendor ecosystems stay where they are — we make them work together.

03 · Established competency

Fintech & Blockchain

Where ProtonChains started, and still delivers. Payment and trading infrastructure on one side, distributed ledgers and smart contracts on the other — in practice the two are usually the same project.

Fintech platforms

  • Trading engine — ready to integrate or built to spec
  • Portfolio management across systems and data sources
  • KYC/AML including sanctions list screening
  • SEPA gateway integration for EUR payments
  • Payment gateway integration

Smart Contracts & Audits

Solidity development for EVM chains, and independent security audits of contracts written by someone else. You get a written audit document, not a verbal opinion.

  • EVM smart contract development
  • Solidity security audits
  • Testnet implementation and joint review

Blockchain integration

Development and integration across 15+ networks — EVM chains (Ethereum, BNB Chain, Avalanche, Polygon, Fantom), the Bitcoin family, plus Tron, Cosmos, Tezos, XRP and Algorand.

  • Digital Asset Custody — build or integrate
  • Digital asset ↔ SEPA (EUR) settlement gateway
  • Tokenization and on-chain records
