Work experience

Frontend Developer

from 06.2024 to now (2 years 5 months)
WireX Systems via SixthSense Technology, Дистанційно (IT)

Built the web client that replaces a legacy Qt desktop application for Ne2ition, the company's network-protocol analysis
platform — the old client only ran on outdated Linux systems. A frontend team of two, with the release pipeline in place
and regular deploys to AWS environments.
Designed a manifest-driven event architecture: a manifest declares what each protocol event shows, builders produce
one normalized view model, and the table, the expanded view, search and sorting all read from it instead of a hand-
written renderer per event type — 70+ event types across 15 protocol categories.
Replaced a deep UI-library component chain inside the recursive renderer with native nodes and virtualized the heavy
expanded lists, which removed the interaction-latency regression on events with hundreds of fields.
Re-architected our event-migration process from one monolithic command into a five-phase suite with on-disk artifacts,
strict context guards and generation delegated to a sub-agent: roughly 8× lower token cost per migrated event, peak
context down by two thirds, and runs that no longer hit the five-hour wall.
Built PDF Creator, a separate internal reporting product: Vite + React + TypeScript with amCharts 5 charts and geo maps,
plus my own Express/TypeScript SSE server — a pool of render clients registering over SSE with available/busy state, a
job queue and file upload, so reports are generated across the pool instead of in one browser tab.

CBS Tech via SixthSense Technology, Дистанційно (IT)

Built promotional sites and landing pages on React and TypeScript, with form validation on zod schemas; state stayed in React's own context — the projects needed no external state manager.
