Senior full-stack engineer from Ukraine, based in Prague, with 9+ years of shipping production products: UX, API design, cloud infrastructure, launch. I've built real-time systems in health-tech, fintech, media, and conferencing platforms.
Now that experience works directly on your project. One person designs it, builds it, launches it — and stays reachable afterwards.
Vue SPA and Electron desktop client for a neural-network face-analysis product, with NestJS/Express APIs over a Python ML inference service.
Full frontend architecture (Vue / Vuex-ORM) for a live trading dashboard with sub-second updates, RxJS real-time streams, and Node/Express services integrating multiple exchange APIs. Led a small team.
GraphQL API layer and HapiJS microservices for audio/video streaming and social feeds, fully containerised with Docker, on high write-throughput MongoDB.
Event-driven AWS services (SQS, SNS, IoT Core, Lambda) for real-time presence and live stats at conference scale, a Redis cache layer that cut peak API latency, plus a Vue 3 frontend and Electron desktop client.
Owned features end-to-end: NestJS/TypeScript services for real-time test monitoring, AWS serverless pipelines (Lambda, S3, API Gateway) for document ingestion and reporting, a WebSocket live-monitoring layer, and secure AWS Chime video workflows.
Experience applied directly to your site and support from the engineer.
