Senior Software Architect | AI-Native Delivery | Regulated & High-Stakes Systems

A deep-tech platform for cryptographic provability of regulated data: organisations can prove that a record exists, is intact and was authored by whom it claims — without a trusted intermediary and without the platform reading the content. Where records concern people, the link between a person and the immutable ledger entry is mathematically erasable, resolving the conflict between blockchain immutability and the GDPR right to erasure. Core invention patent-pending (UIBM, application no. 102026000021355, July 2026).

Designed, built and deployed solo in six months using the human–LLM method described in my profile. Five layers that would conventionally need five teams: five Concordium smart contracts (Rust); the backend platform with zero-knowledge membership proofs, commitment-based signatures and hybrid post-quantum encryption (ML-KEM + HPKE); a cryptographic SDK with a single Rust core running unchanged on server, browser (WASM), iOS and Android; a vertical integration server mapping business domains onto the platform without touching the core; a white-label mobile app factory producing branded, multilingual Android clients from a configuration bundle. 1,057 automated tests, 55,000 lines of specification, hardened production deployment.

Now in pilot with its first vertical: an anonymous ethics channel under the EU Whistleblower Directive, where every report is gated by a zero-knowledge membership proof and attested on-chain. Available for live demonstration.

Co-designed and evolved Psi from inception (2003) to a platform deployed in 20+ banks and EMIs across the EU (Latvia, Lithuania, Bulgaria), UK-jurisdiction EMIs, Ukraine, Azerbaijan and the Philippines, as part of a suite with internet banking, a mobile app and a staff workstation. Implementations included card-processing, SWIFT, SEPA and national payment-system integrations and PSD2/open banking compliance.

Author and developer (Java) of Psi's flow-definition-and-execution engine — the tool in which payment workflows are described and run — and of its business-rules decision engine. Business analyst and project manager on bank implementations, where process descriptions were written as executable code rather than documents. Formally Senior Consultant throughout; architect & lead developer 2021–2026; minority co-owner for a period.

Three positions in Kyiv, Ukraine, 1990–2000 (the platform's date range starts at 1996; actual years are given below).

Dow Jones Telerate, 1994–2000 — Sales & Consultant. Real-time financial market data for banks; in parallel taught finance (portfolio theory, financial instruments, information systems) at the Kyiv Institute of Investment Management.

SoftRating, 1991–1994 — Senior Engineer. Methodologies and systems for software quality assessment and certification.

Technosoft, Kyiv Institute of Cybernetics, 1990–1991 — Engineer, AI & Expert Systems department. Expert systems in Prolog; knowledge visualisation on R-graphs, the graphical formalism of Prof. Igor Velbitsky's R-technology of programming; an expert system deployed in the medical sector for assessing physicians' knowledge after continuing-education courses. Machine reasoning, thirty-five years before today's language models — the same problem, a different generation of tools.
