I'm a senior full-stack engineer with 16+ years of commercial experience. I started at SimbirSoft straight after a non-IT degree, ramped through 30+ projects across very different stacks, and have spent most of the last decade working remotely with clients in the US, Germany, Switzerland and elsewhere.
The last 6.5 years I was at Vereign (Switzerland) building a Zero-Trust authentic-communication platform — primarily on frontend and mobile: cryptographically verifiable email, self-sovereign identity on Credo-TS, IPFS-based storage, mobile apps shipped to the App Store and Google Play, and an Outlook plugin distributed via Microsoft AppSource.
After Vereign I took a year of focused product work — shipping ~20 small experiments and going deep on the modern AI stack (Zencoder + Cursor as primary IDE plugins, plus Claude, ChatGPT, Grok, Perplexity, DeepSeek for product features and research). Now looking to bring this product mindset back into a focused team.
Shipped ~20 small products end-to-end (web apps, Telegram services, landing pages) using AI-assisted workflows (Zencoder + Cursor) and multi-LLM integrations (Claude, ChatGPT, Grok, Perplexity, DeepSeek). Production projects: JusDo (habit tracker), Millionaire Habits (AI-driven analysis of 250 billionaires).
Frontend and mobile engineer on a Zero-Trust authentic-communication platform. Owned the mobile side end-to-end (React Native + Expo, App Store / Google Play). Built the Personal Data Wallet UI on Credo-TS, the Outlook plugin (Microsoft AppSource) and a Chrome extension. Contributed to a Swiss healthcare Zero-Trust project (IPFS, self-signed cert identity) on the frontend/integration side. Contributed fixes upstream to Credo-TS.
Frontend on a complex web app against a Python micro-service backend. Maintained 80%+ test coverage.
Led the AngularJS 1.x → React migration page-by-page in production, with both stacks running side by side. Built new components and post-migration features.
Joined as a junior, promoted to senior in 3 years. 30+ projects across very different stacks (JS, AngularJS, C#, Java, PHP, Ruby on Rails, desktop). Frequently rotated onto troubled projects to stabilize delivery.
