What I'm looking for

I’m looking to build scalable microservices and data pipelines for high-load products, using distributed systems and performance optimization. I want a fast-paced team where I can design for reliability/high availability and help deliver privacy-focused, user-centric platforms.

I’m a Backend Engineer with 5+ years of experience building scalable, high-performance backend systems and data-driven applications. I focus on microservices architecture, data modeling, and data processing pipelines designed for high-load environments.

I’ve designed and implemented scalable microservices and REST API backends for fintech and data-centric workloads, including event-driven architecture with asynchronous processing to improve reliability and scalability. I’ve also engineered data models and database architectures to improve query performance and overall system efficiency.

My work centers on distributed systems, system design, and performance optimization—improving backend latency and throughput by 40%, and strengthening high availability through robust backend architecture and monitoring. I’m passionate about building privacy-focused, user-centric data platforms aligned with modern decentralized technologies.
