What I'm looking for

I seek senior backend or blockchain roles where I can design scalable systems, lead technical decisions, work with cloud native stacks, and drive high‑performance fintech products.

I am a full‑stack engineer with 7+ years focused on fintech and blockchain, building crypto wallets, scalable APIs, and high‑load distributed systems.

I design architectures, lead technical decisions, and implement robust backend services using the .NET ecosystem (4.7–9), CQRS, Event Sourcing and DDD while integrating cloud native tools like Docker, Kubernetes, AWS and Azure.

My work spans blockchain platforms (Ethereum, Bitcoin, Solana), message systems (RabbitMQ, Kafka), databases (PostgreSQL, ClickHouse, MongoDB) and performance optimization for production‑scale systems.
