What I'm looking for

I seek backend roles focused on scalable, secure systems (fintech/blockchain preferred), collaborative remote teams, technical ownership, and opportunities to mentor and design high-load architectures.

I am a backend engineer with over 18 years of experience designing and building scalable, high-performance backend systems across payments, telecommunications, and high-load consumer platforms. I specialize in Go, with additional production experience in Java, Python, C/C++, and distributed architectures.

I have delivered systems that handle millions of users, worked on payment and banking switch services with PCI-DSS and ISO8583 compliance, and built microservices using Postgres, Kafka, Docker and Kubernetes. Recently I focused on blockchain and decentralized technologies, completed formal blockchain and cryptocurrency training, and applied that knowledge toward secure staking platforms and smart contract fundamentals.

I collaborate effectively with distributed international teams, contribute to API design, authentication, scheduling and payment integrations in microservices environments, and mentor through interviewing and candidate evaluation. I am eager to apply backend expertise to secure, efficient systems in fintech, blockchain, and high-load service platforms.
