React Native / Expo engineer, 7 years. I build and ship production mobile apps end-to-end — architecture through store release.
Mobile engineer at Lincoln Labs, Inc. · Tashkent, UTC+5 — a full working day of overlap with Europe, mornings with US East.
Production apps I built as part of the engineering team at Lincoln Labs and previous employers. Store listings are published under each client's developer account.

Take-home projects — built as evaluation assignments, labeled as such
tele-health — Doctor/patient tele-health app on an atomic-design architecture. Exact-slot collision detection with auto-reschedule, local state persistence via AsyncStorage, simulated offline and error handling.
Expo · Jotai · TypeScript
Mecenate — Post feed with likes, comments and WebSocket updates. Built in roughly two hours; its backing API is no longer hosted.
Expo Router · TanStack Query · MobX
Also comfortable with React / Next.js on the web and Node / Express + Postgres on the API side when a project needs it.
Sending a message when the network is up is not the hard part. The subway tunnel is: the radio dies mid-send, the user keeps typing, and everything still has to arrive exactly once, in order.
So I wrote the queue — SQLite persistence, exponential backoff, head-of-line sending, dedupe by client-minted id — and a simulator that attacks it with dropped frames, lost acks, duplicate delivery and connections that die between send and arrival. Nothing reads the wall clock or Math.random, so a failing seed replays exactly.
Every figure in that graphic is output from the run that drew it. CI proves the invariants, re-runs the scenario, and redraws the image; if a fault run goes red, nothing renders.
The queue and its tests · the mutation that proved the suite was testing the wrong thing · no dependencies, Node built-ins only
Open to remote roles and contract engagements — best fit is a team shipping consumer or enterprise mobile apps that needs someone to own the mobile side end-to-end.
