Client work is under NDA, so I describe each project in words instead of screenshots: those illustrations are abstract and use made-up data. The two public websites are real recordings.

ChainComply · 2026
ChainComply's source-of-wealth analysis for individuals: people hand over their exchange accounts and wallets, ChainComply reconstructs how their wealth was built, and they get a claim their bank can read. I own it as its product manager, and designed and built it too.

ChainComply · 2025 – 2026
A B2B2C integration with the crypto tax calculator Kryptos: its users connect their Kryptos account, their history flows into CashoutReady as it is, and they get a source-of-wealth report. I designed and built it.

ChainComply · 2024 – now
The client-facing app where people bring in their crypto for a source-of-wealth review: exchange accounts and wallets from 100+ exchanges and 150+ blockchains, by API or CSV, or from crypto tax calculators. I designed and built it.

ChainComply · 2023 – now
The B2B workspace where compliance officers and tax accountants reconstruct a client's crypto wealth, built for MiCA and EBA guidance: reconciliation, source of wealth, capital gains and P&L, counterparties, source of funds and risk. I designed and built it, and redesigned how analysts move through a case.

The public website I built for CashoutReady: how it works, what the source-of-wealth report contains, and the pricing tiers, in nine languages.
ChainComply · 2025 – 2026
The public website I built for ChainComply, explaining the platform to banks, crypto asset service providers, wealth managers and tax accountants.

Infoleven / Stanga1 · 2022 – 2024
I owned the features clients used most: every data grid, multi-level filtering with user-level persistence, and dynamic forms. Then I redesigned the whole app.

I helped developers integrate KendoReact against strict response times, turned their bug reports into issues the team could prioritise, and kept the documentation current.

In practice I gave Kristina problems rather than specifications, and she came back with finished features, and a few times with whole products.

She is not merely a follower of instructions but rather a keen learner who actively seeks to understand the product.
