I’m a Senior Backend / Fullstack Engineer focused on financial-grade, high-load systems. I specialize in NestJS backend APIs and BFF layers, and I support the frontend with React/Next.js when it helps deliver end-to-end product outcomes.

In my most recent role (2023–2026), I led backend delivery for a multi-product crypto platform—trading bots, wallet, payment, and exchange services. I built domain-split Node.js/NestJS microservices using Kafka/RabbitMQ and gRPC/REST, hardening correctness with idempotent processing, retries with backoff, Redis distributed locks, signed inter-service calls, and audit-grade logs.

I’m comfortable operating in regulated iGaming and fintech contexts where every change must be reviewed, tested, and auditable. I optimize hot paths for sub-second latency using Redis caching, PostgreSQL query/index redesign, and message-queue workers, and I own Kubernetes delivery (Helm, autoscaling, canary) with Prometheus/Grafana monitoring and incident resolution.

Previously (2022–2023), I worked on a top Ukrainian iGaming product serving millions of player sessions, integrating third-party providers behind a unified gateway with strict wallet consistency and multi-PSP payments using idempotent flows and reconciliation. Earlier roles (2018–2021) strengthened my fullstack and API foundation—from production REST services to trader dashboards—while I treat AI-assisted development (Claude Code, Cursor) as a normal part of my everyday workflow.
