Kharkiv, Ukraine · remote

Fullstack developer, 3 years commercial. I ship the backend and the frontend of the same product, then own it in production. Recent: cut a university timetable app's initial load from 4-5s to under a second, a geospatial event platform on PostGIS, and single sign-on across four products against four different OIDC providers. Stack: NestJS, Vue 3, Nuxt, React, Postgres.

Schedule API

NestJS rewrite of a Fastify API. Replaced a separate C# microservice with my own crawler library, moved schedule data from Redis into Postgres with diff-based daily refresh, Redis-backed shareable links.
